How do I find a Bluetooth pairing code?

[Don-308]

So I have a Bluetooth enabled two way radio. A Yaesu FTM-10r to be exact. There were 2 versions of a Bluetooth board for it. First was a BU-1 then a BU-2. The difference was the 2 was a newer board that supported more device connectivity. I currently have the BU-1 installed due to the BU-2 is not available. I’m attempting to pair a Bose Bluetooth headset to it. Nowadays you usually don’t need a pairing code to pair to a device. This radio Bluetooth requires a pairing code in order to pair to the Bose headset. There is no way to set a code from the headset. I’ve contacted Bose asking if there is a default 4 digit pairing code. They never responded. On the radio I have tried all of the default codes that I know and several others. I’ve tried 0000, 1111, 2222, 1234, 0001, etc with no success.
I would imagine there has to be a pairing code in order for the headset to connect to a phone or other device.
Is there a way to find the code that the headset is sending out during the pairing procedure?

Any ideas?

Don.

Make sure they use the same kind of Bluetooth.

BlueTooth (classic or BT) and the low energy BlueTooth LE (BTLE or BLE) are not compatible.  They are both stamped with the same Bluetooth rune symbol, and both have the 'Bluetooth' word in their naming, but they use different data rates, different hopping frequency and different modulation type IIRC.  This is not obvious in most laptops and mobile phones, because they can do both standards, but dedicated devices might not be able to work with any Bluetooth.

Just a hunch, I don't know which kind of Bluetooth is used by the Yaesu modules, or by the Bosse headset.


Assuming your devices are using the more recent 'low energy' Bluetooth, the key exchange (for pairing) can be either:

• OOBK (out of band key exchanging) which means the key is exchanges not by radio, but by other means.  Either a fixed key, or a key sent by plugging the device into a PC, etc.
• password number 0...999999
• 'JustWorks' mode (in which the password number is always '0')

The fact that they were able to test pairing codes means they use a compatible BT type. Devices that only support one type, of the wrong type to pair, can’t even see each other to attempt pairing.
