Setting Tx Power nRF52832

[Declan]

I have a custom beacon with: nRF5_SDK_12.3.0_d7731ad I am using: \examples\ble_peripheral\ble_app_beacon With: \pca10040\s132

When I change the value: int8_t tx_power = 4; OR int8_t tx_power = -40;

I get no change in the range or the RSSI value?

My advertising_init Code:

static void advertising_init(void)

{ uint32_t err_code; ble_advdata_t advdata; ble_advdata_t srdata; uint8_t flags = BLE_GAP_ADV_FLAG_BR_EDR_NOT_SUPPORTED;

ble_advdata_manuf_data_t manuf_specific_data;

manuf_specific_data.company_identifier = APP_COMPANY_IDENTIFIER;

    int8_t tx_power                 = 4;
advdata.p_tx_power_level        = &tx_power;

for changing the tx power level you have to call the function "sd_ble_gap_tx_power_set(4)" for 4dbm,tx_power Radio transmit power in dBm (accepted values are -40, -20, -16, -12, -8, -4, 0, 3, and 4 dBm).

the code which you are referring will include the power level as a part of advertisement packet or scan response packet
