Function Documentation

void es_gatts_handle_read ( nrf_ble_escs_t * p_escs ,
uint16_t uuid ,
uint16_t val_handle
)

Function for handling all read requests from the Central.

Parameters
[in] p_escs Pointer to the Eddystone Configuration Service.
[in] uuid The UUID of the characteristic that is being read from.
[in] val_handle Value handle field of the characteristic handle of the characteristic that is being read from.
void es_gatts_handle_write ( nrf_ble_escs_t * p_escs ,
uint16_t uuid ,
uint16_t val_handle ,
uint8_t const * p_data ,
uint16_t length
)

Function for handling all write requests from the Central.

Parameters
[in] p_escs Pointer to the Eddystone Configuration Service.
[in] uuid The UUID of the characteristic that is being written to.
[in] val_handle Value handle field of the characteristic handle of the characteristic that is being written to.
[in] p_data Pointer to the data to be written.
[in] length Length of the data to be written.
ret_code_t es_gatts_send_op_not_permitted ( nrf_ble_escs_t * p_escs ,
bool op_is_read
)

Function for sending an RW-authorization reply with status 'Operation not permitted'.

Parameters
[in] p_escs Pointer to the Eddystone Configuration Service.
[in] op_is_read Flag that specifies if the operation being responded to is a 'read' operation. If false, a 'write' operation is assumed.
Return values
NRF_ERROR_NULL If p_escs is NULL.
Returns
Otherwise, the error code from es_gatts_send_reply() is returned.
ret_code_t es_gatts_send_reply ( nrf_ble_escs_t * p_escs ,
ble_gatts_rw_authorize_reply_params_t * p_reply
)

Function for sending an RW-authorization reply.

Parameters
[in] p_escs Pointer to the Eddystone Configuration Service.
[in] p_reply Pointer to the reply to send.
Return values
NRF_SUCCESS If the reply was successfully issued to the SoftDevice.
NRF_ERROR_NULL If either of the pointers p_escs or p_reply is NULL.
NRF_ERROR_INVALID_STATE If the connection handle of p_escs is invalid.
Returns
Otherwise, an error code from sd_ble_gatts_rw_authorize_reply() is returned.
