Description

The following function is responsible for sending a SET_REPORT Transaction to the remote HID Device. This function returns zero on successful execution and a negative value on all errors.

Parameters

SetReportRequest uses one parameter, ReportType 0 = rtOther, 1 = rtInput, 2 = rtOutput, 3 = rtFeature.

Possible Return Values

  • (0)HID_Set_Report_Request: Function Successful.
  • (-4) FUNCTION_ERROR
  • (-6)INVALID_PARAMETERS_ERROR
  • (-103)BTPS_ERROR_FEATURE_NOT_AVAILABLE
  • (-1000)BTHID_ERROR_INVALID_PARAMETER
  • (-1001)BTHID_ERROR_NOT_INITIALIZED
  • (-1002)BTHID_ERROR_INVALID_BLUETOOTH_STACK_ID
  • (-1005)BTHID_ERROR_INVALID_OPERATION
  • (-1006)BTHID_ERROR_REQUEST_OUTSTANDING

API Call

HID_Set_Report_Request(BluetoothStackID, HIDID, (HID_Report_Type_Type_t)TempParam->Params[1].intParam, size of(GenericMouseReport), GenericMouseReport)

API Prototype

int BTPSAPI HID_Set_Report_Request(unsigned int BluetoothStackID, unsigned int HIDID, HID_Report_Type_Type_t ReportType, Word_t ReportPayloadSize, Byte_t*ReportDataPayload)

Description of API

The following function is responsible for sending a SET_REPORT request to the remote device. This function accepts as input the Bluetooth Stack ID of the Bluetooth Stack which is to send the transaction and the HID ID for which the connection has been established. The third parameter is the type of report being sent. Note that rtOther is an Invalid Report Type for use with this function. The final two parameters to this function are the length of the Report Payload to send and a pointer to the Report Payload that is sent. This function returns zero if successful or a negative return error code if there was an error.

Note: Control Channel transfers have two phases, a Request by the host and a Response by the device. Only ONE host control channel Request can be outstanding at a time. Reception of an HID Set Report Confirmation event indicates that a Response has been received and the Control Channel is now free for further transactions.
