I'm trying to pair a Bluetooth printer remote to a Windows XP. When manually pairing this to Windows via the BT Add HW Wizard it requires the selection of the "Don't use a passkey" option. Trying to do this programmatically is my issue. I used a API function, BluetoothAuthenticateDevice , to pairing and connecting it. The Bluetooth authentication process has two modes: Wizard mode and Transparent mode I want to provide as "Transparent mode" to user. I've tried string : Empty, "0000", "0000\0" (null-terminated), "1234", "1234\0" (null-terminated), "\0" All to not available. BluetoothAuthenticateDevice(NULL, bdsp.hRadio, &bdi, _T(""), BLUETOOTH_MAX_PASSKEY_SIZE); The result from BluetoothAuthenticateDevice is 87 (ERROR_INVALID_PARAM) Is PairRequest even the right function for this or do devices that don't require passkeys require different methodology to pair/connect to them? Can anyone tell me what I'm doing wrong? Please help me ~~~~~ Thanks deokhee
