5.Serial At Command Description The module will automatically identify and distinguish serial port data. Packets with "AT+" at the beginning will be defaulted to AT commands and parsed, and the processing result will be returned. Therefore, data in transparent transmission mode cannot start with "AT+" characters; non-AT commands The data will be forwarded by the module to the connected Bluetooth terminal 5.1 TEST COMMAN Command format: AT+TEST\r\n Return value: OK\r\n Content: Send AT test command, and re
ERR:CODE\r\n Content: Re-modify the serial port baud rate of the module communication is 115200bps, return OK to indicate that the modification has been successful, and return ERR It means that the new serial port baud rate has failed to be modified, and the serial port baud rate defaults to 115200bps 5.5 Device name operation commands Command format: AT+NAME=WT5105-M1\r\n Return value: OK\r\n ERR:CODE\r\n Content: Rename the module name to WT5105-M1, the length of the name does not exceed 20 bytes Command
means the setting fails 5.7 Bluetooth connection interval setting Command format: AT+CIT=30,45\r\n Return value: OK\r\n ERR:CODE\r\n Content: Set the minimum Bluetooth connection interval to 30ms, the maximum connection interval to 45ms, and the effective Bluetooth connection interval to 10ms-4000ms 5.8 Bluetooth broadcast operation commands Command format: AT+ADV_STOP\r\n Return value: OK\r\n ERR:CODE\r\n Content: Stop Bluetooth broadcast Command format: AT+ADV_START\r\n Return value: OK\r\n ERR:CODE\r\n
means that the module starts to restore the factory mode; Bluetooth connection status, this command is not allowed 5.10 Custom product serial number Command format: AT+SN=1234\r\n Return value: OK\r\n ERR:CODE\r\n Content: The serial number of the custom product is in the broadcast data. If it returns OK, it means that the custom addition was successful, and if it returns ERR, it means that the addition failed. The possible reason is that the custom data exceeds the serial number requirement.
