Send data "+++\r\n" to the Bluetooth serial port or pull down the SET pin to enter the configuration mode("\r\n" is a carriage return and line feed, that is, 0x0d 0x0a). Then send the command "AT+CONS=x,y\r\n", where x must be greater than 0 and x+y<=20. The module returns OK to indicate that the setting is successful, restart the module to make the configuration take effect.

3.2 Open FR801xH_OTA, find the BLE module BLE5101, click to connect to Bluetooth.

After the connection is successful, click 1 to select upgrade firmware (it is recommended to put the firmware in an easy-to-find phone directory), and then click 2 to start writing.

The writing of the firmware takes a while. After writing, the BLE module BLE5101 will automatically restart and install the firmware. So far, the BLE5101 has been upgraded.
