Question

,We are planning to use the TRB145 for SMS alarms in our systems.

Also as a replacement for existing systems. Unfortunately, the modem does not work there because the telephone number of the SMS recipient must be given in quotation marks and the software does not use quotation marks in the existing systems. It is possible to enter the telephone number without quotation marks. The software on the existing systems can no longer be changed. Therefore the TRB145 cannot be used.

at+cmgs="+43664123......" will work well

at+cmgs=+43664123...... should work well too

Answer 1

Hello,

Unfortunately, this is not possible. Quotation mark allows defining a multiple symbols value such as phone number. AT or gsmctl commands cannot read number values without it.

Regards.

Answer 2

Hello. Thanks for the quick reply. But that's a pity and also strange. We have been using our system for 20 years and with at least 3 GSM modems. So far, all of them have worked without the quotation mark. Unfortunately we can no longer use the GSM modem because the 3G network is switched off and we have to switch to 4G.

Regards.
