We not have it.
MikroTik as vendor of lte modules not give us even a basic AT Commands manual.
For discovery.. we know what SoC is inside what lte module and we discover some information.
We must use a GOOGLE or check some AT Coomands manuals who have sometimes that information or ask directly
support@mikrotik.com .
Very important is to use latest version of lte module
