 * @param[in] p_input           Pointer to the description of the payload.
 * @param[out] p_buff           Pointer to payload destination. If NULL, function will

 *
 * @param[in,out] p_len         Size of available memory to write as input. Size of generated
 *                              payload as output.
 *
 * @retval NRF_SUCCESS          If the payload was encoded successfully.
 * @retval NRF_ERROR_NO_MEM     If the predicted payload size is bigger than the provided buffer space.
