Question

How can I increase the TX power on nRF5_SDK_15.3.0?

I tryed declared the m_advertising struct without success... 
 I compared the advertising_start() function of ble_app_beacon and ble_app_proximity examples... 
 
 ble_app_proximity example: 
 /**@brief Function for starting advertising.
 */
static void advertising_start(bool erase_bonds)
{
 if (erase_bonds == true){
 delete_bonds();
 // Advertising is started by PM_EVT_PEERS_DELETE_SUCEEDED event.
 }
 else
 {
 uint32_t err_code = ble_advertising_start(&m_advertising, BLE_ADV_MODE_FAST);

 APP_ERROR_CHECK(err_code);
 }
} 
 The parameter used in ble_advertising_start is m_advertising . 
 
 ble_app_beacon example: 
 /**@brief Function for starting advertising.
 */
static void advertising_start(void)
{
 ret_code_t err_code;

 err_code = sd_ble_gap_adv_start(m_adv_handle, APP_BLE_CONN_CFG_TAG);
 APP_ERROR_CHECK(err_code);

 err_code = bsp_indication_set(BSP_INDICATE_ADVERTISING);
 APP_ERROR_CHECK(err_code);
}
 
 The parameter used in sd_ble_gap_adv_start is m_adv_handle . 
 
 So i changed the handle parameter of sd_ble_gap_tx_power_set function to m_adv_handle and works good! 
 uint32_t err_code = sd_ble_gap_tx_power_set(BLE_GAP_TX_POWER_ROLE_ADV, m_adv_handle, 4); 
 
 I don't know if what i did is correct but i can measure the difference on power TX... 
 Can i keep this modification? 
 What is the difference of ble_advertising_start and sd_ble_gap_adv_start ? 
 
 PTS.: I also find in main() of ble_app_beacon example: 
 static uint8_t m_adv_handle = BLE_GAP_ADV_SET_HANDLE_NOT_SET; 
 
 Thanks

Hi, 
 It should be alright. It's effectively the same, ble_advertising_start() calls sd_ble_gap_adv_start(), see the definition of the function.
