How to set tx power using using ble_tps function?

[ande_dewal]

hi everyone ,

I have problem to set tx_power in my ble_ibaecon code.

I  referred  sdk15.0.0 ble_peripherals/ble_app_beacon example.

a ) First, I tried using below function

advertising_init();
err_code = sd_ble_gap_tx_power_set(BLE_GAP_TX_POWER_ROLE_ADV, m_adv_handle,RADIO_TXPOWER_TXPOWER_Pos4dBm);
APP_ERROR_CHECK(err_code);
advertising_start();

after that i read  NRF_RADIO->TX_POWER register , it gives always 0dbm.

b) I have problem

how to used this function  ble_tps_tx_power_level_set(ble_tps_t * p_tps, int8_t tx_power_level)  for set tx_power. 

please, someone help me to solve this problem.

Please check out this case, where the sd_ble_gap_tx_power_set() function is explained and discussed in detail. 

It seems like you're trying to call this function in the main loop itself, is that right. Please try adding it to the end of your advertising_init(); function, below the APP_ERROR_CHECK(err_code); of sd_ble_gap_adv_set_configure() in the default example.

Also, at what point do you read the TX_POWER register?

Best regards,

Simon
