Detailed Description

Functions for handling GATTS write and read requests.

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 *	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.
