Where is initial value of transmit power in nrf51822 ?

[shinho]

Hi I am trying to change the radio's transmit power in program, but I can't solve it.

I downloaded nRF51822 Beacon v1.1.0. and am testing PCA20006. (Source Code\nrf51_beacon\ble_app_beacon\pca20006)

I am making an admin program for iOS7 device to configure advertising interval and power level.

First of all, I could not find where is initial setting of transmit power level. Even though I changed most of setting related power level, it does not work.

Secondly how to set Power Level of nRF51822 from iOS? I searched most of answers here devzone, can't find proper answers.

I spent several days to make this program and still working on without success.

I'm sorry I can't tell you where you find the initial value but for me changing it with just these 1 line works fine:

sd_ble_gap_tx_power_set(4);

(accepted values are -30, -20, -16, -12, -8, -4, 0, and 4 dBm) But just reference it. And if I remember correctly default value is 0.

Initial value for the S110 is 0dB. I found that using a forum search, it's been confirmed as 0dB a number of times.
