question

I tried entering 000000 but it wouldn't accept this as correct. It requests me to enter the code shown on the BMV. Unfortunately the device code has a "t" as one of the characters and the keyboard on the Victron app doesn't appear to have a way of entering a "t". When the firmware update hanged at 75% - for about 20 minutes - I stopped it as the update stated that if I was forced to interrupt the download I could restart without problem. It wouldn't restart so, as suggested by Victron, I removed the device and tried to re-pair it. This is where I'm having the problem. At some point it stated that the BMV had no firmware!!! Help please.

Hi @DBP

Unfortunately, iOS shows a generic pincode popup that assumes that the product has a display that shows the pincode. This is not the case in our products, but we cannot do anything about the iOS popup. In the end, it is asking for the pincode. When it does not accept the expected pincode (apperently you did not change the pincode so it should still be "000000"?), the pincode has to be reset using the procedure which I also linked above: https://ve3.nl/VictronConnect_ResetPIN

After resetting the pin, you should be able to pair using "000000" and finish the update.

Thanks for the explanations and I've managed to pair the BMV 712 but it now shows zero readings. Has it lost everything in the Firmware update?

The display on the device also shows bt200 on the screen.

Hi @DBP

The fact that the screen says "BT200" means that it is in firmware update mode and waiting for a new firmware. From your other answer, I suspect that you only see a product information screen that only shows 1 device, instead of 2 that you would normally see for a SmartBMV 712. To be sure, can you please post a screenshot of what you are seeing in VictronConnect after connecting to the SmartBMV?

If this is indeed what I suspect, then it means that the internal Bluetooth dongle is unable to communicate with the BMV part of the SmartBMV. What you can try is to power cycle the BMV by disconnecting the grey cable going into the back of the BMV712 for a minute and then plugging it back in. Afterwards, connect with VictronConnect. When it then still only shows a product info screen with just the dongle, then there is a hardware problem with the BMV.

Dear Theimo,

I've run through your suggestions. Having got the correct passcode to get me paired it then asked me to perform the Firmware upgrade which, this time, ran perfectly. The bt200 screen changed and I appear to back running again except I now need to run a charge cycle before resetting 100%. Thank you so much for your helpful explanations.
