7. PHYSICAL INTERFACES 7.1 UART Interface WT11 Universal Asynchronous Receiver Transmitter (UART) interface provides a simple mechanism for communicating with other serial devices using the RS232 standard1. UART_TX UART_RX WT12 UART_RTS UART_CTS Figure 6: WT11 UART interface Four signals are used to implement the UART function, as shown in Figure 11.12. When WT11 is connected to another digital device, UART_RX and UART_TX transfer data between the two devices.
UART Configuration While RESET is Active The UART interface for WT11 while the chip is being held in reset is tri-state. This will allow the user to daisy chain devices onto the physical UART bus. The constraint on this method is that any devices connected to this bus must tri-state when WT11reset is deasserted and the firmware begins to run. 7.2 USB Interface WT11 USB devices contain a full speed (12Mbits/s) USB interface that is capable of driving a USB cable directly.
and PSKEY_USB_PIO_WAKEUP to the selected PIO number. USB_DETACH is an input which, when asserted high, causes WT11 to put USB_DN and USB_DP in high impedance state and turned off the pull-up resistor on D+. This detaches the device from the bus and is logically equivalent to unplugging the device. When USB_DETACH is taken low, WT11 will connect back to USB and await enumeration by the USB host.
consists of six programmable, bi-directional I/O lines, PIO[2:7]. Programmable I/O lines can be accessed either via an embedded application running on WT11 or via private channel or manufacturer-specific HCI commands. All PIO lines are configured as inputs with weak pull downs at reset. PIO[2] / USB_PULL_UP (1) This is a multifunction terminal. The function depends on whether WT11 is a USB or UART capable version. On UART versions, this terminal is a programmable I/O.
9. SOFTWARE STACKS WT11 is supplied with Bluetooth v2.0 + EDR compliant stack firmware, which runs on the internal RISC microcontroller. The WT11 software architecture allows Bluetooth processing and the application program to be shared in different ways between the internal RISC microcontroller and an external host processor (if any). The upper layers of the Bluetooth stack (above HCI) can be run either on-chip or on the host processor. 9.

SOLDERING 10.1 Reflow Soldering The soldering profile depends on various parameters necessitating a set up for each application. The data here is given only for guidance on solder re-flow. There are four zones: 1. Preheat Zone - This zone raises the temperature at a controlled rate, typically 12.5°C/s. 2.
Certifications WT11 is compliant to the following specifications 10.2 Bluetooth The WT11-E module is Bluetooth qualified and listed as an end product. If not modified in any way, it is a complete Bluetooth entity, containing software and hardware functionality as well as the whole RF-part including the antenna. This practically translates to that if the module is used without modification of any kind, it does not need any Bluetooth approval work.
10.3 FCC Federal Communications Commission (FCC) Statement 15.21 You are cautioned that changes or modifications not expressly approved by the part responsible for compliance could void the user’s authority to operate the equipment. 15.105(b) This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
10.4 CE WT11 meets the requirements of the standards below and hence fulfills the requirements of EMC Directive 89/336/EEC as amended by Directives 92/31/EEC and 93/68/EEC within CE marking requirement. • Electromagnetic emission EN 301 489-17 V.1.2.
