6.17 Get Class of Device

Description

The GetClassOfDevice command is responsible for querying the Bluetooth Class of Device of the local Bluetooth Device. This function returns zero on a successful execution and a negative value on all errors. A Bluetooth Stack ID must exist before attempting to call this function.

Parameters

Including parameters when using this command is not necessary. A parameter has no effect on the outcome of the query.

Possible Return Values

  • (0) Successfully Queried Local Class of Device
  • (-57) BTPS_ERROR_DEVICE_HCI_ERROR
  • (-2) BTPS_ERROR_INVALID_BLUETOOTH_STACK_ID
  • (-8) INVALID_STACK_ID_ERROR
  • (-4) FUNCTION_ERROR
  • (-1) BTPS_ERROR_INVALID_PARAMETER

API Call

GAP_Query_Class_Of_Device(BluetoothStackID, &Class_of_Device);

API Prototype

int BTPSAPI GAP_Query_Class_Of_Device(unsigned int BluetoothStackID, Class_of_Device_t *Class_of_Device);

Description of API

This function is responsible for querying (and reporting) the class of device of the local Bluetooth device. The second parameter is a pointer to a class of device buffer that is to receive the Bluetooth class of device of the local device. If this function is successful, this function returns zero, and the buffer that Class_Of_Device points to fill with the Class of Device read from the local Bluetooth device. If there is an error, this function returns a negative value, and the class of device of the local Bluetooth device is NOT copied into the specified input buffer.
