How to decode protobuf in Node Red?

[martinwozenilek]

When I try to decode the protobuf messages from a nRF52 device in Node Red I get this error message:

Wire format is invalid: Error: no such Type or Enum 'MeshPacket' in Type .meshtastic.ServiceEnvelope

For decoding I'm using node-red-contrib-protobuf in version 1.1.2. Some other users had the same problem but never get a working answer in the old discourse group.

And by the way: will json format come to the nRF52 devices or is this completely impossible? This is very important for me as I use the Mesh mainly for telemetry data.

Closed. I've recognized that my Meshtastic MQTT gateway, which is Raspberry Pi based, does the conversion from protobuf to json already. This way I can use my nRF52 devices for telemetry data.
