SMS modem - oliver.brown.knx - 16.03.2025
Hello,
What modem would you recommend to send an SMS from a logicmachine through USB. Ideally with an external antenna. Could you also please provide code to communicate with it.

Hi Oli,
Why don't you use Lm5p2-rio3 LTE.
Best regards Cristian

Hi Cristian,
because this is an existing installation where units are already installed that are without LTE.

Hi. I successfully using Cinterion BGS2T modem with RS-232 port. Connected to LM USB port used USB2RS232 cable with adapter. Working 7 years already.
But this is 2G modem. Possibly soon in my country will be switched off 2G/3G standard support, later will go to LTE/5G modem, will see..

The replacement for BGS2T could be Cinterion EGX81 IoT gateway.
I found this on a discussion here: https://forum.logicmachine.net/attachment.php?aid=32
, but it's a very old document.

Nearly all modems support AT commands which are used for sending SMS. Integration script should work with modems: https://kb.logicmachine.net/notifications/sms/
We can't guarantee that USB modem will work because it usually requires a specific command for switching into a working state. The command is specific for each manufacturer/model.
RS-232 is preferred over USB for stability reasons.

Hi Admin,
thank you for your answer.
So I should look for a modem with RS232 and connect to LM to RS232.
Please recommend specific modem models, or what specific parameters should I look for when choosing.
RE: SMS modem - admin - 17.03.2025
Any modem with RS232 should work. To be sure check that AT commands are supported.

Okay, thanks for the answer.
How to set the modem with RS232 to send sms? Is there any specific instruction?
