Set Idle Request

Description

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

Parameters

SetIdleRequest requires one Parameter which is Idlerate.

Possible Return Values

  • (0) HID_Set_Idle_Request: Function Successful
  • (-4) FUNCTION_ERROR
  • (-8) INVALID_STACK_ID_ERROR
  • (-1000)BTHID_ERROR_INVALID_PARAMETER
  • (-1001)BTHID_ERROR_NOT_INITIALIZED
  • (-1002)BTHID_ERROR_INVALID_BLUETOOTH_STACK_ID
  • (-1004)BTHID_ERROR_INSUFFICIENT_RESOURCES
  • (-1005)BTHID_ERROR_INVALID_OPERATION
  • (-1006)BTHID_ERROR_REQUEST_OUTSTANDING

API Call

HID_Set_Idle_Request(BluetoothStackID, HIDID, (Byte_t)TempParam->Params[0].intParam)

API Prototype

int BTPSAPI HID_Set_Idle_Request(unsigned int BluetoothStackID, unsigned int HIDID, Byte_t IdleRate)

Description of API

The following function is responsible for sending a SET_IDLE transaction to the remote HID Device. This function accepts the Bluetooth Stack ID of the Bluetooth Stack which is to sendthe request and the HID ID for which the Connection has been established. The last parameter is the Idle Rate to be set. The Idle Rate LSB is weighted to 4 ms (i.e. the Idle Rate resolution is 4 ms with a range from 4 ms to 1.020 s). This function returns a 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 Idle Confirmation event indicates that a response has been received and the Control Channel is now free for further transactions.
