Unable to query Zombieverter VCU parameters #4

Closed davefiddes closed 5 months ago

davefiddes commented 5 months ago

Reported by evMacGuyver

It seems that when trying to query the (Zombieverter VCU](https://github.com/damienmaguire/Stm32-vcu) OIC silently fails.

A SavvyCAN capture of the CAN traffic is attached. zombieverter-node3-query-paramdb.csv

It seems that the devices was running 2.17.A firmware.

It looks like oic fails with this error:

$ oic -d zombie.json listparams
