1.1.2.1.2.4.3 GATTC_DiscoverAllPrimaryServices

uint16_t GATTC_DiscoverAllPrimaryServices(uint16_t connHandle);

GATT Client starts the discovery of all primary services when this API is called. All primary services in the handle range 0x0001 - 0xFFFF will be discovered with a single call to this API.

The event GATTC_EVT_DISC_PRIM_SERV_RESP may be generated multiple times until all services are discovered.

Following events may be generated on the GATT client:

• Event GATTC_EVT_DISC_PRIM_SERV_RESP with procedureStatus in GATT_EvtDiscPrimServResp_T set to continue. This indicates some services are found but the discovery of all services is not complete. (See p_attrData in GATT_EvtDiscPrimServResp_T for extracting service data received.)

• Event GATTC_EVT_DISC_PRIM_SERV_RESP with procedureStatus in GATT_EvtDiscPrimServResp_T set to Finish. This indicates termination of the procedure (End Handle for last found service is 0xFFFF. See p_attrData in GATT_EvtDiscPrimServResp_T for End Group Handle of a discovered service)

• Event GATTC_EVT_ERROR_RESP with error code ATT_ERRCODE_ATTRIBUTE_NOT_FOUND is generated. This indicates termination of the procedure. (End Group handle of last found service is less that 0xFFFF)

GATTC_EVT_ERROR_RESP Generated when service not found or discovery procedure is end.

GATTC_EVT_DISC_PRIM_SERV_RESP Generated when services discovered from remote.

ATT_EVT_TIMEOUT Generated when server does not respond the request.
