CMS ERROR: 512 User abort

Added by admin over 8 years ago

At first it seemed to be working great on a MultiTech modem, I started the connection to the modem and I was able to send some SMSs. I never got to receive any SMS. It seemed kind of weird to me because I was using your standard code so what I did is I tested it with another modem, an Enfora GMS0308 kit and it works great, I'm able to send and receive messages without a problem.

I'm writing you because we need to make it work with the MultiTech modem but I'm not sure of the problem, I've read the log and did a little investigation but never got to the solution.

On this email I'm attaching the code I'm using and also the log file. Please let me know if there's something to do to make it work on the MultiTech demo, at first the SMS send was working but it suddenly stopped working on this modem.

CMS error 512 is returned by the message center so there must be something incorrect in the message settings which causes this.

We tried to decode one of the message, see below

Few things that you can try

2. Try to set the destination number in international format (start with "+")
