10.12 LE Query Encryption

Description

The LEQueryEncryption command is responsible for quering the Encryption Mode for an LE Connection. This command returns zero on successful execution and a negative value on all errors.

Parameters

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

Possible Return Values

  • (0) Successfully Queried Encryption Mode
  • (-4) FUNCTION_ERROR
  • (-8) INVALID_STACK_ID_ERROR
  • (-2) BTPS_ERROR_INVALID_BLUETOOTH_STACK_ID
  • (-1) BTPS_ERROR_INVALID_PARAMETER
  • (-56) BTPS_ERROR_GAP_NOT_INITIALIZED
  • (-104) BTPS_ERROR_LOCAL_CONTROLLER_DOES_NOT_SUPPORT_LE

API Call

GAP_LE_Query_Encryption_Mode(BluetoothStackID, ConnectionBD_ADDR, &GAP_Encryption_Mode)

API Prototype

int BTPSAPI GAP_LE_Query_Encryption_Mode(unsigned int BluetoothStackID, BD_ADDR_t BD_ADDR, GAP_Encryption_Mode_t *GAP_Encryption_Mode)

Description of API

This function is provided to allow a means to query the current encryption mode for the LE connection that is specified.
