I hope this is the right place to ask the question .
I have TANGO 864-2 modem that was connected to a HMI software thorugh RS232 and sent SMS , from what i know it uses AT commands to communicate with the modem . Now , i connected instead of it the FX100 modem , and it refuses to send SMS . Could be that old device and does not have the same AT commands for this ?
(Sorry if this is a stupid question )
Tjank you in Advance.
Can you provide a link to describe what, exactly, that is
What “HMI software”, exactly
Again, a link would help.
Do you get any error messages
The commands for sending SMS should be standard - but it’s possible that the mystery “HMI software” is relying upon other specific features of the “TANGO 864-2” …
You’re going to have to do some more investigation to find where exactly the process is failing…
