Concatenated AT-commands

3 thoughts on “Concatenated AT-commands

  1. In Telit AT Controller I found concatenated commands: AT#MONI;#MONI.


    After checks, I found that it is possible to concatenate even 3 same or differen commands, by adding ";" char and removing leading AT. The command answers come in same order as commands.


    How many commands is possible to be sent in such manner? Up to filling MDM/MDM2 buffer or SER buffer?


    1. Hi Nikolay,


      From AT Commands reference Guide:


      The command line buffer accepts a maximum of 80 characters. If this number is exceeded none of the commands will be executed and TA returns ERROR.
