In earlier versions of the TRB142 the serial Bidirect mode worked but in the latest version of the OS 2.05.1 it no longer works.
The application we have has a device on the serial port (115200, 8, none ,1) that communicated back to a central server (10.0.0.1).
In server mode with TCP port 15000 we can connect to the device from our server and the communications works.
In client mode with the setting 10.0.0.1:15000 our device can connect to the server and the communications work but the connection is closed (I suspect from the server end). Once the connection is closed the server can not reconnect to the field device.
The issues arise as the Instrumentation is run from solar panels/batteries and so we only turn the modem on at specific times or when the field device needs to upload data.
In the previous OS the bidirect mode worked and allowed the connection to be initiated from either end. Is there something in the new OS version that has changed this? Is there anyway to downgrade from OS Version 2.05.1 to an earlier version?
Thanks in advance for any help you can provide.
