BoT-CLE310 User Manual
Operation Description BoT-CLE310 BLE wireless Module transmits and receives 2.4GHz frequency The default operating voltage is 3.3 V, and the BLE transmission / reception data is processed by the main processor BoT-CLE310 wireless transmit / receive data operates with AT + Command stored in main processor.
BoT-CLE310 Protocol (AT-COMMAND) OVERVIEW This document defines a communications protocol through UART (serial port) between customers’ MCU (hereinafter referred to as “HOST”) connected with "Chipsen BoT-CLE310 BoT-CLE1X0 Module" (hereinafter referred to as “BT”) and UART interface. 1.1. Basic Protocol Rule • The transmission and receipt of data between the HOST and the BT is based on the UART(serial port) interface.

1.3.2 BYPASS mode The BT is capable of transmitting to the Remote device DATA generated in the HOST by being connected with Remote device. This state is called the BYPASS mode. In the BYPASS mode, it is not possible to change the settings of the the BT device or perform a specific operation. 1.4.
GPIO3 is high when Server or Client is connected. GPIO3 is low when Server or Client is disconnected. 1.5.2. Low-power operation (GPIO4) The BT always enters the low-power mode in a situation where it is available. In the low-power mode, there may occur an omission of data transmitted using UART in the HOST. When data to be transmitted in AT command or with the Remote devices is sent to UART, be sure that a low-power GPIO4 must be kept high.
AT+MANUF=xxxxxxxx AT+MANUF? AT+TXPWR=x AT+TXPWR? Used when the name of Manufacturer is changed In case of Manufacturer using this command, device manufacturer information will be changed in the Discoverable mode. MAX 8byte Request the Manufacturer Used to adjust the TX power level of the BT; the power level will be automatically applied after the use of this command.
AT+CONNECT=xxxxxxxxxxxx Request connection when you know the Bluetooth Address intended to be connected to. E.g.) AT+CONNECT=74F07DB00001 AT+RECONNECT Request connection to the device which was last connected to. AT+AUTOCONNECT? Request automatic connection configure AT+AUTOCONNECT=ON Set Enable automatic connection to the device which was last connected to.
4.1.1 Structure Packet types are as follows, and the Index position of the packet may be variable depending on the data length.
Description If the device receives the Request and performs the command normally, respond with “+OK” and then reset it in 2 seconds. Usage (HOST→BT) : ATZ example (BT→HOST) : +OK (BT→HOST) : +READY The reset can be identified with the reset performance and + READY response. 5.1.
Description If the device receives the Request and performs the command normally, respond with “+OK” and display the address, device name, and role. Usage (HOST→BT) : AT+INFO? example (BT→HOST) : +OK (BT→HOST) : 74:F0:7D:B0:10:00, BoT,SERVER[PERIPHERAL] You can know obtain information about the address of the BT, the name of BoT, and the Server Role from the Host device 5.1.
5.2. Server AT Command 5.2.1. Operation AT+SERVER=ROLE Used to change the role of the BT in the HOST when the BT is in the SERVER mode Response +OK or +ERROR Description If the device receives the Request and performs the command normally, respond with “+OK” and then reset it. Otherwise, respond with "+ERROR." Usage example (HOST→BT) : AT+SERVER=P (BT→HOST) : +OK The BT begins operating as the Peripheral device 5.2.2.
0( -18dBm), 1(-14dBm), 2(-10dBm), 3(-6dBm), 4(-2dBm), 5(2dBm), 6(6dBm), 7(8dBm) 5.2.1. AT+TXPWR? Operation If you want to know BT TX Power Response +OK or +ERROR Description If the device receives the Request and performs the command normally, respond with “+OK” and then display the value of the TX Power. Usage example (HOST→BT) : AT+TXPWR? (BT→HOST) : +OK (BT→HOST) : 4 You can know obtain from the Host device information that the TX Power of the BT is 4(-2dBm) 5.2.2.
example (BT→HOST) : +OK (BT→HOST) : Data12 You can know obtain from the Host device the information that the Advertising User Data of the BT is Data12. 5.2.1. AT+ADVINTERVAL=xxxx Operation If you want to change the Advertising Interval of the BT in the HOST Response +OK or +ERROR Description If the device receives the Request and performs the command normally, respond with “+OK”; otherwise, respond with “+ERROR.
current Connection Interval (current Connection Interval with the remote device), request the change of the Connection Interval after 30 seconds the connection (The Default Connection Interval immediately after the connection is about 30ms). Actually updated connection values are negotiated ones and equal to or less than the requested values, depending on the remote devices. Requested values should not exceed 4 seconds suggested in the specifications.
example (BT→HOST) : +OK The BT is rebooted in 2 seconds and operates with the Central device. 5.3.1 AT+SCAN Operation Search for the SERVER device in CLIENT Response +OK or +ERROR Description If the device enters the SCAN state normally, respond with "+SCANNING" and then do with +OK after a 15-second Scan. Otherwise, respond with "+ERROR.

Operation If you want to know the size of the SCAN Window of CLIENT in the HOST Response +OK or +ERROR Description If the value of the Scan Window is read normally, display the size of the SCAN Window and then respond with "+OK." Otherwise, respond with “+ERROR.
Usage (HOST→BT) : AT+RECONNECT example (BT→HOST) : +OK (BT→HOST) : +CONNECTED[xx:xx:xx:xx:xx:xx] Request connection with the SERVER recently connected to the BT in the Host device and get connected 5.3.1 Operation AT+AUTOCONNECT? Request the setting status of AUTOCONNECTION with the SERVER recently connected in CLIENT Response +OK Description If Request is made normally, respond with “+OK.” If AUTOCONNECTION is set, respond with “ON.” Otherwise, respond with “OFF.
6. General Data transmission . The data that receives UIART after the SERVER is connected with the CLIENT BLE device or the data that is transmitted through the BLE link from the remote device is automatically transmitted without transformation. State The state where SERVER and CLIENT are connected to each other Usage (HOST→BT) : ABCD example 7.
