Gaps in VRM graph drawn by Globallink 520 data

I've got the Globallink520 installed now for a few days and am experiencing some strange gaps in the graphs in the VRM portal. Some data (here consumed Ah) is even barely recorded.

Anyone else having this too? What could be the reason for this? These appear not only in this custom widget, but others and preset ones too.

My guess is that the gaps comes from where the GL has not been sending any data/lost contact to LTE-M network. This is based on how I see my GL behaviour.

Hm, I highly doubt that, as other graphs in the same timeframe are being drawn.

Where is the battery data coming from? A shunt or a BMS?

Could just be that the sensor has fault or connectivity issue.

BMV-712 hence the shunt. With temp it’s even more worse, just some dots and short lines.
