I have a modbus device connected through tb-gateway, where I can read from device.
I'm strugling to use a RPC to write to device. I read this doc thingsboard.io/docs/user-guide/rpc/#server-side-rpc-api and I can read from device.
Now I want to send a command to write in a tag and I read this doc thingsboard.io/docs/user-guide/rpc/#server-side-rpc-api but I don't know where to put modbus RPC code. The documentation is not clear for me.
Is someone using Thingsboard RPC to write in modbus devices?
