Concatenating AT Commands
Concatenating AT commands on the same line is possible, though not recommended because of restrictions
listed below (for more details see ITU-T V.250
).
When concatenating AT commands you need to enter the "AT" or "at" prefix only once at the beginning of a com-
mand line. Basic commands (i.e., ITU-T V.250 commands) are concatenated without delimiter. Extended com-
mands (i.e., commands starting with AT+ or AT^) use a semicolon as delimiter.
Disadvantages and restrictions:
•
There is no way to control the minimum time to wait between finishing an AT command and sending the next
one. Please refer to Section
Communication between Customer Application and BGS2T
for details about
timing.
•
The sequence of processing the AT commands may be different from the sequential order of command input.
•
Many AT commands cannot be concatenated (see list below). Concatenating these commands might end up
with an error result code, or leads to an unexpected order of responses.
