PLS8-X : AT&T 3G dialing issue | Thales IoT Developer Community

April 20, 2016 - 10:30am, 5256 views


We're having troubles when trying to connect to AT&T network during a series of tests last week in the U.S., especially when we sent dialing command for 3G connection : ATD*99***1#<CR><LF>

Can someone confirms our AT dialing command is correct ?

When connects to AT&T or Verizon :
- Do the dialing command requires a specific syntax ? (I heard, without being able to validate the information, that a semicolon might be added at the end of ATD*99***1# ... is it a possibility ?)
- Are we miss some specific steps, for connecting, the other providers do not requires ?

ATI4 of or our PLS8-X :

A-REVISION 01.000.00<CR><LF>

We're using, before dialing the AT+CGDCONT=1,"IP","***"<CR><LF> command.

Thanks in advance...
