Hello,
Thank you for more information.
Take note that "RUT955's RS232 Modem mode" only allows "Partial modem control" and only support the following commands:
Therefore with "RUT955's RS232 Modem mode" you will not be able to acquire desired information from the router. In this case:
- You can either use any other RS232 mode (e.g. "RS232 console mode") and communicate with router using SSH commands instead of AT command
- Or you can use different Teltonika device - TRB142 - which has full modem mode support and allows you to fully control device (and acquire all information) through AT commands via RS232.
Regarding "ATI" command itself: Yes, you can at "ATI" command to the router, just not through "RS232-modem mode". This command returns "LTE module manufacturer, LTE module type and LTE module revision" information. Router's response to this command cannot be customized.
Nonetheless, there should be no need for that, since all this information from router can be retrieved via separate AT commands, e.g.:
- AT+GMI returns LTE module manufacturer
- AT+GMM returns LTE module type
- AT+GMR returns LTE module revision
Of course, with other AT commands other information could also be read from the router.
