question

Hi @Zane Jackson

Looks like the update process gets interrupted for some reason, resulting in incomplete firmware in your bmv712. The notification "BT200" indicates this state.

Can you try making a service report? If you have never done this before please check https://www.victronenergy.com/media/pg/VictronConnect_Manual/en/troubleshooting.html?utm_source=offline&utm_medium=qr&utm_campaign=qr%20code%20products#UUID-98bc9211-902b-01a0-96b9-1f314c4d63c5

Hopefully this service report tells us something about the reason why the update process is interrupted.

One last question: do you remember what the version of the bmv712 was before the update was started? v4.0x???

hi @Zane Jackson

Thanks for the report. I can see the update failing repeatedly but unfortunately it's not completely clear why this is happening. My guess would be a hardware failure but based on this report I can't be 100% sure.

You could try to do a wired update in case you haven't tried that, for which you'll need a "VE.Direct to USB" cable. However, in case the problem is indeed a hardware failure then I don't expect a wired update to work either. I then advice you to get in contact with your supplier/distributor.

One more question: have you ever updated the firmware of this bmv in the past (I mean the bmv v4.0x firmware; not the Bluetooth interface v2.xx firmware)?

The software update process itself is indeed fail safe. But in this case it seems like the hardware is failing and unfortunately the software is not able to fix such failing hardware.

Looking at the service report you sent it seems your device is still within its 5 year warranty period. If you go to https://professional.victronenergy.com/support/?is_next=www.victronenergy.com you can create a service request to find the distributer who sold this bmv which you can then contact to get your bmv replaced.
