Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 2. µP Interface This design will be HCI only using the H4 protocol for serial communications. The baud rate will be set at 115.2K. 3. Persistence Storage Keys The following is a table covering the PS Key addresses and settings for each location. Please refer to the latest CSR document for updated PS Key settings.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 default frequency block by January 2001. 0 North America and Europe, except ... 1 France 2 Spain 3 Japan Key Name PSKEY_CLASSOFDEVICE Key Number Type Default Setting 0x0003 bdcod 0 The local device's default Bluetooth "class of Device" or CoD. Type bdcod is really a uint32. The class of device is a 24 bit value stored in a uint32; the highest byte must be zero. This is the device's default class of device, used when the device boots.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 to the accuracy of that external clock. PSKEY_DEEP_SLEEP_STATE = ALWAYS_ACCURATE (3): PSKEY_DEEP_SLEEP_USE_EXTERNAL_CLOCK should be TRUE, so set device drift to the accuracy of the external clock. Key Name PSKEY_DEVICE_JITTER Key Number Type Default Setting 0x0005 uint16 10 This should hold the local device's radio jitter in microseconds. (LMP v1.1, section 5.2.) This value is used in LMP_timing_accuracy_res messages sent to peers.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 This value is constrained by the value of the pskey PSKEY_MAX_REMOTE_MASTERS. The "barge-in" connection sequence (an existing master page-scans, it is paged by new a device, then the new device's link performs a master/slave switch) implies a temporary scatternet. This pskey does not affect this behaviour. See the description of PSKEY_MAX_REMOTE_MASTERS. (Type bool is fundamentally a uint16 with values 0 and 1 mapping to FALSE and TRUE.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 This supports the Host_Buffer_Size HCI command. See the description of PSKEY_H_HC_FC_MAX_SCO_PKT_LEN. Key Name Key Number Type Default Setting PSKEY_LC_FC_BUFFER_LOW_WATER_MARK 0x0015 lc_fc_lwm 0x0600, 0x0700, 0x0800 A set of values that control the assertion of flow control for data received from air.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 For BlueCore01b, the key's range is normally 0x04 to 0x3f. 0x04 gives the slowest ramp rate. Although the hardware supports values below 0x04, using them will put the software timings so far out that the module may not work. The key's value has different effects according to whether the module uses the chip's internal power amplifier or an external amplifier. (See PSKEY_TXRX_PIO_CONTROL.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 specified in PSKEY_LC_ATTEN_GOLDEN_RANGE_MAXIMUM you should get this RSSI reading for a signal at the top of the golden receive range. Taking this signal above 90 can lead to faulty behaviour. If a -60 dBm signal with an attenuation of 1 gives an RSSI above 90 then leave this setting at 90 as you have a module with good sensitivity.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 A two-element array of uint16s specifying the use of PIO lines to indicate the occurrence of priority Bluetooth activity (transmit or receive): { uint16 pio_mask, uint16 pio_invert } Bits 0 to 15 of "pio_mask" and "pio_invert" map to PIO0 to PIO15 respectively. A bit of "pio_mask" set to high enables driving of the corresponding PIO pin to indicate priority activity.

For example, power_setting { 0x0d11, 0, 0x3f11, 0x4d00, 0xf800 } specifies: To get power output -8 dBm for basic data rate (1 Mbps) use internal amp 13, external amp 17. To get power output -8 dBm, for enhanced data rate (2 or 3 Mbps) use internal amp 63, external amp 17, TX-PRE amp 0x4d. A power table is a list of these entries. The entries must be in ascending order of transmit power.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 PSKEY_LC_WIDEBAND_RSSI_CONFIG 0x0032 wideband_rssi_config 113, 98, 9, 50 Hardware from BlueCore3-Ext has a facility for wideband RSSI measurement. This key is used to configure the settings. It consists of four 16-bit words. The first word is the value of the wideband RSSI reading above which the RSSI high target should be reduced. The second word is the value of the wideband RSSI readinb below which the RSSI high target should be increased.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 remaining scan window. The intention is to save power when there are no other devices nearby. Key Name Key Number Type Default Setting PSKEY_CONDITIONAL_SCAN_THRESHOLD 0x0037 uint16 0x0060 RSSI threshold for energy detection. Pre-BC5 two bytes are used. The lowest byte is the narrow band RSSI threshold. This is in LSB for the ADC, not in mV. The upper byte is the number of LSB above baseline for the wide band RSSI.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 PSKEY_AGC_HYST_LEVELS 0x003d agc_hyst_config 0x8, 0x6, 0xb, 0x9 BlueCore contains an automatic gain control algorithm which attempts to maintain a reasonable signal level by adding and removing various sources of attenuation. This key controls the signal strength at which these sources are added and removed. It should not be altered except on advice from CSR.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 resynchronising. This PS key holds a time indicating how long the master has to have not heard from the slave before it will start using single slot packets to help the slave resynchronise. One way to calculate a good time is to know that in low power modes, the error between the master and slave's clock can grow at up to 500 ppm (since each device's clock is allowed to be upto 250 ppm from nominal).
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 PSKEY_EDR_MODE_SWITCH_PIO 0x0052 uint16 none This key will assert the PIO line specified, 0-15 if present, if the key is not present it will become a zero length key with an attempt to read it failing, this will fail the psget method and disable use of this key. If the pskey is defined but the value is 0xffff, out of bounds, then the key will not setup a pio line.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 paired with decrement peer power period. (Type TIME is fundamentally a uint32. Value SECOND is 1000000. Value MILLISECOND is 1000.) Key Name Key Number Type Default Setting PSKEY_LC_PEER_POWER_DECR_PERIOD 0x0058 TIME 1 * SECOND The period, measured in microseconds, between attempts to decrement the peer's transmit power, the same interval is used for measurements of channel quality to support LMP channel quality driven data rate messages.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 0 COEXISTENCE_NONE PIO is not used (high impedance) 1 COEXISTENCE_BT_OUTPUT PIO is asserted for the duration of SCO and eSCO reserved slots With current firmware builds this should be left at its default of COEXISTENCE_BT_OUTPUT, with the functionality enabled or disabled by modifying PSKEY_LC_COMBO_DOT11_PERIODIC_PIO_MASK as appropriate.

Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 This pskey can hold a maximum of 20 uint16s, limiting the default device name to 40 octets. The behaviour is undefined in this pskey holds more than 20 uint16s. (This size constraint does not apply to a name written via the HCI Change_Local_Name command.) The default name for BlueCore3 chips is "CSR - bc3"; when packed this becomes {0x5343, 0x2052, 0x202d, 0x6362, 0x0033}. This pskey is used from (HCI) 18.X builds. HCI 17.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 This key defines the minimum amount by which the device will change a channel map. If the channel map is rapidly changing by only a very small amount then the device prefers not to send too many channel map changes of classification reports. The first number is the number of channels that must have got worse to cause the device to send a message.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 bucket works. The firmware also stops conditional scanning for this period when it receives an inquiry or when the last connection has just ended, returning the firmware to the idle state. Conditional scanning is never performed in the connected state.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 Key Name Key Number Type Default Setting PSKEY_HOLD_ERROR_MESSAGE_NUMBER 0x0113 uint16 1 Maximum number of HCI Hardware Error Events which maybe present in the queue of HCI events being sent to the host. If this is set to 0 then no limit imposed.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 When performing Simple Pairing the ECC key pair should be protected. There are 3 methods for this: - Change the private key after three failed pairing attempts or after 10 successful pairing attempts or a combination of these such that 3 successful attempts count as one failed attempt. - Verify that the received public key are on the correct curve.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 PSKEY_DFU_TRANSFER_SIZE 0x0138 uint16 1023 The wTransferSize field of the run time DFU Functional Descriptor, as defined in Table 4.2 of USB DFU specification 1.0. This key applies to both the USB and "DFU over UART" (protocol name not yet allocated) protocols. The maximum permissible value for this key is 1023 for both transports. (This limit is imposed by the USB hardware). The default value (1023) is in bytes.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 This is a 32-word array containing the more significant block of the R2N multiplier for DFU signing of a VM application. See PSKEY_DFUENC_VMAPP_PK_R2N_LSB for the other part. Key Name Key Number Type Default Setting 0x0162 uint16[] none PSKEY_DFUENC_VMAPP_PK_R2N_LSB This is a 32-word array containing the less significant block of the R2N multiplier for DFU signing of a VM application. See PSKEY_DFUENC_VMAPP_PK_R2N_MSB for the other part.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 The configuration uses a structure of type HOSTIO_FC_PS_BLOCK in which the only field currently used is: bool allow_sco_fc - if TRUE then the chip will allow SCO over HCI flow control to be turned on, else it will be refused. The remaining fields are redundant: uint16 ncp_max_period - the default milliseconds between sending NCP (hci number of completed packets) events to the host.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 int:1 reliable_stream - TRUE if the protocol uses BCSP's reliable stream. int:4 priority - A value between 0 and 7. Lower values have higher priority. The priority is used by the chip's BCSP scheduler when deciding what data to send to the host. int:1 enabled - TRUE if the protocol is enabled. The current design of the firmware code requires each protocol to be enabled explicitly internally by the firmware, so this flag should always be FALSE.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 channel is available for all host transports. The protocol is configured with a PROTOCOL_INFO structure. The structure is described in the information on PSKEY_HOSTIO_PROTOCOL_INFO0. Key Name Key Number Type Default Setting PSKEY_HOSTIO_PROTOCOL_INFO5 0x0199 PROTOCOL_INFO 259, TRUE, 5, FALSE Configure the protocol that flows over channel 5. This channel carries HCI commands and events. This channel is available for all host transports.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 Number PSKEY_HOSTIO_PROTOCOL_INFO9 0x019d PROTOCOL_INFO 2048, TRUE, 7, FALSE Configure the protocol that flows over host transport channel 9. This channel carries RFCOMM traffic. This channel is available for all host transports. The protocol is configured with a PROTOCOL_INFO structure. The structure is described in the information on PSKEY_HOSTIO_PROTOCOL_INFO0.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 PSKEY_HOSTIO_PROTOCOL_INFO14 0x01a2 PROTOCOL_INFO 0, TRUE, 7, FALSE Configure the protocol that flows over host transport channel 14. This channel is unallocated. Since this is the last free channel, anything that needs an extra channel should multiplex within this channel. This channel is available for all host transports. The protocol is configured with a PROTOCOL_INFO structure.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 PSKEY_HOSTIO_USE_HCI_EXTN_CCFC 0x01a6 bool FALSE If the system is using hci_extn to carry the non-HCI channels (see the description of PSKEY_HOSTIO_USE_HCI_EXTN) and this key is TRUE then the chip emits an "hci command complete event" for each HCI manufacturer extension command.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 Use the BCCMD (private channel) command MAP_SCO_PCM to cause the next HCI Add_SCO_Connection command to route to a PCM port. Use this pskey. If this pskey is TRUE then all attempts to open SCO connections map to PCM ports. I.e., this pskey overrides the BCCMD command. In HCI 14.X builds, only a single SCO stream can flow over the BlueCore2-EXT's PCM port. In HCI 15.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 transport - BCSP and H4. (USB has separate rules for defining SCO transport.) Audio people will want this set to zero to minimise audio data latency, however this can crowd other data off the host transport. When the available host bandwidth is too low this can block all other traffic, so HCI ACL, HCI CMD/EVT, etc. stop flowing.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 described in bc01-s-010g. The new protocol only differs significantly from the old one in that: - The "choke" is turned off when moving from "curious" to "garrulous". - The "cnf_cnt_limit" logic is removed; "conf" messages are continuously emitted in the "curious" state. It may be necessary to set this pskey to TRUE if the host has an old implementation of bcsp-le See the comment for PSKEY_BCSP_LM_CNF_CNT_LIMIT.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 On devices with a codec (except BlueCore2-External) this is: Bits [2:0] set the analogue gain (5 = unity gain) Bits [7:4] set the digital gain (0 = unity gain) Bits [9:8] set the sigma-delta gain (0 = nominal) On BC5-MM Bit [10] enables an extra 3dB of gain on DAC_A Bit [11] enables an extra 3dB of gain on DAC_B On BlueCore2-External, this is Bits [2:0] set the gain (7 = maximum gain) Key Name PSKEY_CODEC_IN_GAIN Key Number Type Default Settin
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 the buffer. The thresholds are held as a uint16[2]. The first value gives the lower threshold and the second value gives the upper threshold. This PS key has no effect on some versions of firmware. Key Name Key Number Type Default Setting PSKEY_HOSTIO_SCO_HCI_THRESHOLDS 0x01bc uint16[] 10, 80 Sets the upper and lower thresholds for the buffers used to hold SCO data flowing between air and the HCI.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 devices; automatic detection of Baud rate does not work for the DFU upgrade procedure. When the system is configured to use a UART-based host transport, i.e. if PSKEY_HOST_INTERFACE selects BCSP, H4, H5 or User (VM access to the UART), then the UART's Baud rate is set to the value of this PS key when the firmware boots. The PS key's value is: Baud rate = pskey_value/0.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 PSKEY_UART_CONFIG_H4 0x01c0 uint16 0x08a8 If PSKEY_HOST_INTERFACE selects use of H4 then the UART's configuration register is set to the value of this PS key when it boots. The UART configuration register is a bitfield and shares its format with PSKEY_UART_CONFIG_BCSP: Bit Meaning 0 0 => one stop bit, 1 => two stop bits. 1 0 => no parity bits, 1 => one parity bit. 2 0 => odd parity, 1 => even parity.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 (The "H5" host transport protocol is properly known as the "Three Wire Uart Transport Layer", but is commonly known as H5 within CSR.) Key Name Key Number Type Default Setting 0x01c2 uint16 0x08a8 PSKEY_UART_CONFIG_USR If PSKEY_HOST_INTERFACE selects use of VM access to the UART then the UART's configuration register is set to the value of this PS key when it boots.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 This pskey is also used with H5. (The "H5" host transport protocol is properly known as the "Three Wire Uart Transport Layer", but is commonly known as H5 within CSR.) Key Name Key Number Type Default Setting 0x01c5 uint16 0 PSKEY_UART_TX_MAX_ATTEMPTS The description of PSKEY_UART_ACK_TIMEOUT outlines BCSP's mechanism to retransmit reliable messages to the host until acknowledged.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 Most systems do not require the BlueCore to emit a wakeup signal to wake up the peer device. Systems using the BCSP transport, for example, support the host and baseband entering a deep sleep state, in which their UARTs are disabled. The devices may enter deep sleep when they choose, without warning that they are about to enter deep sleep and without signaling when they are in deep sleep.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 the host may be in a low power state. PSKEY_UART_HOST_WAKE enables this wakeup signalling and specifies the various timers required. PSKEY_UART_HOST_WAKE_SIGNAL is used to specify the wakeup signal to use: this is a UART break signal, a pulse on a PIO line or, for the H4DS transport only, a repeated byte sequence. This PS key's value is a bitfield, allocated as: bits 0 to 3: Host Wake Mechanism.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 11 Set to 1. 12 0 => H5 operation disabled, 1 => enabled. 13 Set to 0. 14 Set to 0. 15 Set to 0. The default value, 0x08a8, selects use of hardware flow control, as required by the H4 (sic) specification. Key Name PSKEY_H4DS_WAKE_DURATION Key Number Type Default Setting 0x01cc uint16 0x0020 The H4DS protocol requires BlueCore to wake the host if it believes the host may be asleep.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 Wake-Up messages. This pskey sets the duration of the timer. The pskey's value is in milliseconds. Key Name Key Number Type Default Setting PSKEY_H4DS_UART_IDLE_TIMER_PERIOD 0x01d1 uint16 50 The H4DS specification requires a device to detect when the UART has become idle.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 Key Name Key Number Type Default Setting 0x01f6 uint16 0x1d PSKEY_ANA_FTRIM BlueCore uses a crystal as the basis of all of its accurate timing, notably radio frequency control, UART baud rate and precise event timing. Each real crystal oscillates at a slightly different frequency. This ps value trims the crystal to an optimal value. This value must be set per crystal, i.e.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 0 - No chip to host connection 1 - BCSP 2 - H2 - USB 3 - H4 - UART 4 - VM access to the UART 6 - H5 7 - H4DS 9 - SDIO (The "H5" host transport protocol is properly known as the "Three Wire Uart Transport Layer", but is commonly known as H5 within CSR.) Key Name PSKEY_HQ_HOST_TIMEOUT Key Number Type Default Setting 0x01fb TIME 5 * SECOND Each HQ message sent to the host should provoke a corresponding reply from the host.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 This pskey enables the security mechanism. When a BlueCore module is freshly manufactured this bool flag is set FALSE. The host may then read and write all ps values and can run all of the BCCMD commands. This allows the manufacturer to configure the Bluetooth module. When the configuration is complete the manufacturer sets this pskey to TRUE. This enables the ps and bccmd access controls.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 Bits 0 to 7 of this uint16 pskey map to PIO0 to PIO7 respectively. If a bit of the pskey's value is set high then application code cannot change the value of the corresponding PIO port pin. NOTE: On the current Casira motherboard, PIO2 is connected to USB+ via a 1k5 resistor. The USB+ pin doubles as the UART RTS line on BlueCore, so care must be taken if an application uses PIO2.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 it will be sent at the old rate. The preferred method is to change this PS key then to reboot the chip. Although this key can be set higher, the maximum rated speed for the UART hardware is 1.5 Mbaud. This is a presentation PS key. PSKEY_HOSTIO_UART_PS_BLOCK is the real data store, but this key should be used to access it.

Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 Internal PA gain setting at which to perform IQ trim auto-calibration. If the pskey value is higher than the maximum level in the power table (see PSKEY_LC_POWER_TABLE) the firmware will silently limit it to the power table's maximum internal PA setting. Bits [11:8] set the transmitter pre-amplifier gain while bits [7:0] set the maximum allowed power amplifier gain (but a lower value may be used).
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 Applies when the host interface is BCSP, TWUTL or VM access to the UART, and depends on the key PSKEY_DEEP_SLEEP_STATE being set to allow deep sleep. If we have had no transmission from the host for at least this number of milliseconds, and we have no data to send, then we may go into deep sleep, depending on restrictions from any other source.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 Parameter for the IQ trim auto calibration routine. Selects whether phase trimming is done as part of the IQ trim routine. If this is set to disabled then the appropriate bits from PSKEY_IQ_TRIM are used.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 link is removed. Most of the buffer resources can be freed as soon as the handle is redirected. The buffer page table address however is cached by the CSR chip hardware during the reception of a hci data packet payload. The page table thus cannot be destroyed for a period equal to the duration of the largest packet that the host can send. (Type TIME is fundamentally a uint32. Value SECOND is 1000000.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 host flow control tokens are flushed. This delay is required to workaround a race hazard in the hci specification. The host might not acknowledge packets sent around the time when it is sent a disconnect event - the buffers used for these packets should thus be assumed to be free by the host controller.
Datalogic Scanning, Inc 959 Terry Street Eugene, Oregon 97402 reference is required (for instance, when the BlueCore is in deep sleep). If set to 0, no PIO is used as a clock request.
