Hi Naveen,
Thanks for your response. I currently do have access to FOTA, which allows me to perform actions on device management such as firmware.
My usecase is slightly more specific, I would like to pass a msg to the RS232 (RX) in order to prompt a command on the RS232 connected sensor. My anticipation would be that sending custom command is not possible via FOTA (However I stand to be corrected), with that assumption I would be believe a feasible solution would be to establish an SSH tunnel with the device and action accordingly.
If you know of any documentation that could assist me in achieving that - I would really appreciate it.
