Hi

I have paired FMB122 with OBDII. It communicates and send data to my gpstrace only for a one Trip and then I start receiving no data: whether driving or stopped.

Whenever iam connected, I get all my OBDII data at every instance (data packet sent) when FMB120 is connected

What could be the problem?

After some time i remove the device, Attach to the configurator, Re Pair it with OBD2, but this solutions works for some time only.1 or 2 trips only.

Initially SMS obdinfo, Return with Protocol ID (Non zero) and PIDs (Non Empty) but latter on in other trips i get Protocol ID = 0.

Hello,

Thank you for your query.

Please provide firmware version of the FMB120 or FMB122. You can use the latest firmware 03.25.14.Rev.03 which has more stable bluetooth connectivity. For firmware download please contact your sales manager.
