BLE - default power (dbm)

[Roei]

Hi,

I'm using nrf52840 with BLE functionality.

I don't use sd_ble_gap_tx_power_set in my application.

Does it mean that I'm using default power (dbm)?

What is the default power?

Thanks!

Hello,

I'm using nrf52840 with BLE functionality.

Yes, that is correct. If you do not use the sd_ble_gap_tx_power_set function the SoftDevice will use the TXPOWER's default value.

What is the default power?

The default value of the RADIO peripherals TXPOWER register is 0x0, which corresponds to 0 dBm.

Best regards,
