The correct GAP role to use with the Beacon sample is 'BLE_GAP_TX_POWER_ROLE_ADV' as it only advertises. Maybe you supplied the wrong handle argument to sd_ble_gap_tx_power_set()? This will cause the function to return with an error (followed by a reset if you use the default SDK error handling - Error module).

Please try setting the TX power in the advertising_init function as the snippet below shows.

/**@brief Function for initializing the Advertising functionality.
 *
 * @details Encodes the required advertising data and passes it to the stack.
 *          Also builds a structure to be passed to the stack when starting advertising.
 */
static void advertising_init(void)
{
    ...
    
    err_code = sd_ble_gap_adv_set_configure(&m_adv_handle, &m_adv_data, &m_adv_params);
    APP_ERROR_CHECK(err_code);

    err_code = sd_ble_gap_tx_power_set(BLE_GAP_TX_POWER_ROLE_ADV, m_adv_handle, 8);
    APP_ERROR_CHECK(err_code);
}

Best regards,
