Set Command:
AT+RFPOWER=<wifi_power>[,<ble_adv_power>,<ble_scan_power>,<ble_conn_power>]
OK
<wifi_power>: range [0, 11]
‣ 0:level 0. Refer to the 44th byte of phy_init_data.bin, the default value is 19.5 dBm
‣ 1:level 1. Refer to the 45th byte of phy_init_data.bin, the default value is 19 dBm
‣ 2:level 2. Refer to the 46th byte of phy_init_data.bin, the default value is 18.5 dBm
‣ 3:level 3. Refer to the 47th byte of phy_init_data.bin, the default value is 17 dBm
‣ 4:level 4. Refer to the 48th byte of phy_init_data.bin, the default value is 15 dBm
‣ 5:level 5. Refer to the 49th byte of phy_init_data.bin, the default value is 13 dBm
‣ 6:level 5 - 2 dBm. For example, if level 5 is 13 dBm, level 6 will be 11 dBm
‣ 7:level 5 - 4.5 dBm
‣ 8:level 5 - 6 dBm
‣ 9:level 5 - 8 dBm
‣ 10:level 5 - 11 dBm
‣ 11:level 5 - 14 dBm
<ble_adv_power>: RF TX Power of BLE advertising, range: [0, 7]
‣ 0:7dBm
‣ 1:4dBm
‣ 2:1dBm
‣ 3:-2 dBm
‣ 4:-5 dBm
‣ 5:-8 dBm
‣ 6:-11 dBm
‣ 7:-14 dBm
<ble_scan_power>: RF TX Power of BLE scanning, range: [0, 7], the same as
<ble_adv_power>
<ble_conn_power>: RF TX Power of BLE connecting, range: [0, 7], the same as
<ble_adv_power>
The RF TX power may not be very precise, it is normal that the actual RF TX power is
•
different from the setting value.
The last three parameters,[<ble_adv_power>,<ble_scan_power>,<ble_conn_power>],
•
should be set or be omitted altogether.
