BGS2T - EHS5T AT command difference | Thales IoT Developer Community

February 7, 2021 - 4:17pm, 8557 views


For a long time I have been using a device (Natural Gas Volume Corrector) that manages the BGS2T device with AT commands.
I am communicating with my Natural gas volume corrector device (ModBus protocol) via BGS2T.

I want to switch to 3G or 4G due to the problems experienced in GPRS.
 bought the EHS5T terminally PLS62T. But I could not communicate with both.
When I watched the communication between the Natural Gas volume correction device and EHS5T over RS485 communication, I noticed that there was an error in the AT+GMR command in the figure below.

AT+GMR function is valid for BGS2T but not for EHS5T and PLS62T. I found that AT+CMGR for EHS5T and PLS62T have the same function, but I do not have the opportunity to change the commands of the Natural gas volume corrector.
How can I resolve this situation?
