[GE865] Can't open socket

Wireless & IoT
1

I was hoping someone here could help me with a socket dial using the Telit GE865. When I do any of the socket dial AT commands, it just freezes…it never says NO CARRIER or CONNECTED…it just freezes. The only way for me to communicate with the GSM module after this is to turn it off and then back on. Here’s the sequence of commands I’m using (on AT&T):

AT+CGDCONT=1,"IP","WAP.CINGULAR"
OK
AT#USERID="WAP@CINGULARGPRS.COM"
OK
AT#PASSW="CINGULAR1"
OK
AT#GPRS=0
OK
AT#GPRS=1
+IP: 10.110.125.164


OK
AT#SKTD=0,80,"www.bluehost.com" <-It never returns from this

I’m kind of thinking it might be something related to flow control (I have disabled all flow control and only have Tx and Rx connected). Any thoughts?

Figured out the solution (of course, right after I asked for help), so here it is in case anyone else is having trouble:

Apparently hardware flow control has to be explicitly disabled every single time the module is turned on. Even though the command AT&K? returns 0, I still have to run AT&K=0. After this, the sockets operate as I expect them to.
