Open mrangics opened 7 months ago

mrangics commented 7 months ago

Describe the issue I would like to use RPC to update registers on ModBus devices connected to ThingsBoard with Thingsboard Gateway. There is a documentation available, but it's incomplete, please complete it. https://thingsboard.io/docs/iot-gateway/guides/how-to-use-rpc-modbus-connector/

Configuration (Attach your configuration file) tb_gateway.json

Connector name (If you need help with some connector/converter): modbus_.json

Error traceback (If it was raised): Request Time out.



**Versions (please complete the following information):**
 - OS: [Ubuntu 22.04]
 - Thingsboard IoT Gateway version [3.4.2]
 - Python version[3.11]

@HarvUK , yes, my ModBus connector matched this, that's why I'm asking for help using the RPC, it looks like the definition is good in my connector - if you think not good, please orient me, I have uploaded my connector file.

Thanks, Máté

Partially successful. RPC sometimes is being sent, sometimes not, more investigation is necessary.

Good afternoon, could you give a concrete modbus_.json for one device using rpc, the variant you have works
