Hi @redasdasd ,

It looks like your Modbus server returns wrong data or disconnects the gateway by timeout. We have added parameters retryOnInvalid and retryOnError - please try to use the version from the master branch and let us know about the results.

Hello, where are the thingsboard_gateway/connectors/modbus/modbus_connector.py and thingsboard_gateway/connectors/modbus/modbus_connector.py. My thingsboard-gateway is installed in Raspberry Pi 4. I can only find /etc/thingsboard_gateway/config/modbus.json

Hi,

Usually the gateway source code located in /usr/local/lib/python3.X/dist-packages or in /usr/lib/python3.X/dist-packages/, where X - subversion of your python. We are going to publish release on Monday, so you can just wait and update it after this weekends.

I have checked these documents last week. The file I found is as shown below: raspberrypi4:/usr/lib/python3/dist-packages/thingsboard_gateway/connectors/modbus $ ls bytes_modbus_downlink_converter.py bytes_modbus_uplink_converter.py init.py modbus_connector.py modbus_converter.py pycache

Hi @redasdasd ,

The new version of the gateway is available, please update your instance and try again.
