OBD dongle mac address change and failure to reconnect

Avatar
 Panagiotis Malakoudis

Whenever OBD BLE dongle mac address changes (this happens with my dongle every time I unplug/replug it) I need to reconfigure the ABRP OBD connection. The name of the device does not change - it is always the same. Name of my device is vLinker MC-IOS. Can you make it possible to always connect to same device name even if mac address changes? That way it would connect automatically every time. Now I always have to reconfigure it. I attach two screenshots with the different mac address in OBD scanning.

Hi Panagiotis,

This is normal for this device and we describe it here; www.iternio.com/abrp-obd

You should be able to determine which device is the correct one by looking at which is presented in bold text. However, we have no way of really knowing and therefore all available devices near you are presented.

Vgate vLinker MC+ does not need pairing in BLE mode. It does pairing only in bluetooth mode. At least my dongle does that. That's why I don't leave it always connected. It does indeed change mac address every time. Car Scanner Pro has kind of fixed this by having an option "Automatically search for Bluetooth LE device with the same name". So app tries to connect with a device with same name but different mac address, and works. It would be nice if you could implement this feature.
OBDLink CX does not change address every time it is plugged?
