Default Tx power level set in s130.

[Raghu GS]

HI, I wanted to know what is the default tx power set level in S130, I took a example from sdk 11.0.0, (ble Peripheral/ble_app_uart) but i dont see anywhere this example used this function(sd_ble_gap_tx_power_set) to set the tx power, it means that defaultly the softdevice s130 V2.0.1 has set the tx value within the acceptable range (accepted values are -40, -30, -20, -16, -12, -8, -4, 0, and 4 dBm), Can i know what is that default value set and where can i find it?

Hi Raghu,

The default TX power with the softdevice is the same with the default TX power in the radio TXPOWER register which is 0x00 (0dbm)

We could have had mentioned it clearer in our softdevice spec.

Thanks for the reply Hung Bui. It helped a lot.

Hi Hung,

There is any updates about including this info in the SofDevice specs ?

Hi Arthur,

The softdevice doesn't change the default TX power in the radio hardware. So the information 5 years ago still the same.
