Rf Bluetooth Transmitting Power Setting; Ble Broadcast Interval Setting - Waveshare RP2040-BLE User Manual

3.3 RF BLUETOOTH TRANSMITTING POWER SETTING

AT+BR01\r\n
AT+BR09\r\n
Note:
1. Changes take effect immediately after being sent.
2. The valid range for values is [0 to 9].
3. Values are automatically saved when power is disconnected, and the next power-up will use
the saved value.
4. The chip defaults to the maximum power of 9.
5. Higher transmission power results in a broader broadcast range but relatively higher power
consumption.

will return the current broadcast interval parameters.
