0x01: 1 second, 0x02: 2 seconds, 0x03: 3 seconds...0x0A: 10 seconds…0x1E: 30 seconds…
If it is disabled, the corresponding command code is 88 02 03 [00] AA.
For example, let’s change the disconnection time to 10 seconds.
Then, the correct command code is 88 02 03 [0A] AA.
If the setting is successful, the BLE module will send back the command code 88 02 03 0A AA, and the LED2 will

-4dBm 0x03 -20dBm 0x06
For example, let’s change the transmission power to -8dBm.
Then, the correct command code is 88 02 04 [04] AA.
If the setting is successful, the BLE module will send back the command code 88 02 04 04 AA, and the LED2 will
flash one time. Otherwise, the setting was failure.
