Hi,
In firmware TRB2_R_00.02.03.1 on TRB255 most of the gsmctl CLI commands (including all AT commands eg. gsmctl -A AT+XXX) do not work.
Unfortunately it does not seem to be possible to send AT commands via the CLI (eg. gsmctl -A AT+CIMI should retrieve the IMSI from a BG96 but the CLI says that it cannot understand the command
In the CLI, most of the gsmctl commands (even single parameter commands) are either "not understood" by the interpreter "timeout", or take a very long time to respond (eg. try to get the imsi with gsmctl -x). This still occurs when we put it into debug mode.At this stage it may take >30 seconds for some of these commands to respond, if they respond at all. For the IMSI command, I have only had 1 successful response from this command as 99% of the time it fails. The device has definitely read the IMSI by this time as it is connected to the internet and successfully transmits data over our IPSec tunnel. I have pasted findings from this in blue below:
eg.
root@Teltonika-TRB255:~# gsmctl -v
GSMCTL version: 0.2b
root@Teltonika-TRB255:~# gsmctl -k
root@Teltonika-TRB255:~# gsmctl --at AT+CIMI <-- Dead
root@Teltonika-TRB255:~# gsmctl -x <-- Dead
root@Teltonika-TRB255:~# gsmctl -i <-- Dead
Failed to invoke a gsmd object method
