6.7 Pass Key Response

Description

The PassKeyResponse command is responsible for issuing a GAP Authentication Response with a Pass Key value via the input parameter. 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. The device must also be in the middle of an on-going pairing operation that was started by the local device or a remote device.

Parameters

The PassKeyResponse command requires one parameter which is the Pass Key used for authenticating the connection. This is a string value which can be up to 6 digits long (with a value between 0 and 999999).

Command Call Examples

  • "PassKeyResponse 1234" Attempts to set the Pass Key to "1234."
  • "PassKeyResponse 999999" Attempts to set the Pass Key to "999999." This value represents the longest Pass Key value of 6 digits.

Possible Return Values

  • (0) Successful Pass Key Response
  • (-6) INVALID_PARAMETERS_ERROR
  • (-8) INVALID_STACK_ID_ERROR
  • (-2) BTPS_ERROR_INVALID_BLUETOOTH_STACK_ID
  • (-1) BTPS_ERROR_INVALID_PARAMETER
  • (-57) BTPS_ERROR_DEVICE_HCI_ERROR

API Call

GAP_Authentication_Response(BluetoothStackID, CurrentRemoteBD_ADDR, &GAP_Authentication_Information);

API Prototype

int BTPSAPI GAP_Authentication_Response(unsigned int BluetoothStackID, BD_ADDR_t BD_ADDR, GAP_Authentication_Information_t *GAP_Authentication_Information);

Description of API

This function is provided to allow a mechanism for the local device to respond to GAP authentication events. This function is used to specify the authentication information for the specified Bluetooth device. This function accepts as input, the Bluetooth protocol stack ID of the Bluetooth device that has requested the authentication action, and the authentication response information (specified by the caller).
