  • Hi.

    Do you mean the radio's transmit power?

    You can set that by calling sd_ble_gap_tx_power_set().

    For SoftDevice S132 V6.1.0, the API is:

    /**@brief Set the radio's transmit power.
     *
     * @param[in] role The role to set the transmit power for, see @ref BLE_GAP_TX_POWER_ROLES for
     *                 possible roles.
     * @param[in] handle   The handle parameter is interpreted depending on role:
     *                     - If role is @ref BLE_GAP_TX_POWER_ROLE_CONN, this value is the specific connection handle.
     *                     - If role is @ref BLE_GAP_TX_POWER_ROLE_ADV, the advertising set identified with the advertising handle,
     *                       will use the specified transmit power, and include it in the advertising packet headers if
     *                       @ref ble_gap_adv_properties_t::include_tx_power set.
     *                     - For all other roles handle is ignored.
     * @param[in] tx_power Radio transmit power in dBm (see note for accepted values).
     *
      * @note Supported tx_power values: -40dBm, -20dBm, -16dBm, -12dBm, -8dBm, -4dBm, 0dBm, +3dBm and +4dBm.
      * @note The initiator will have the same transmit power as the scanner.
     * @note When a connection is created it will inherit the transmit power from the initiator or
     *       advertiser leading to the connection.
     *
     * @retval ::NRF_SUCCESS Successfully changed the transmit power.
     * @retval ::NRF_ERROR_INVALID_PARAM Invalid parameter(s) supplied.
     * @retval ::BLE_ERROR_INVALID_ADV_HANDLE Advertising handle not found.
     * @retval ::BLE_ERROR_INVALID_CONN_HANDLE Invalid connection handle supplied.
     */
    SVCALL(SD_BLE_GAP_TX_POWER_SET, uint32_t, sd_ble_gap_tx_power_set(uint8_t role, uint16_t handle, int8_t tx_power));

    Best regards,
