Can someone help in deciphering the above errors? I also get the same issue using Mikrotik CHR

It looks like your EM160R-GL firmware is intolerant of composite AT commands.

This is where AT commands are chained together with semi-colons, which replace all but the first “AT”.

The basic mechanism is shown in 3GPP 27.007, section 4.1.

Hi I’ve been able to solve the problem. The issue was the pcie adapter that didn’t provide a stable connection for the firmware update to work. I’ve since changed adapter and it worked perfectly
