For a brief moment I had this working, but after a hiccup with my hologram service, it has stopped. I’m not sure if it’s the modem, or my hologram service, but any help is appreciated.
I was running a TCP server directly from the modem with the following
AT+CGSOCKCONT=1,"IP","hologram"
AT+CSOCKSETPN=1
AT+CIPMODE=1
AT+NETOPEN
AT+SERVERSTART=3000,0
Now when I run those commands and try to send a “Cloud Data” message from my dashboard to the device, it returns “Failed to connect to device to send message” and the device console doesn’t output anything
I am however able to open a connection to the hologram server using
AT+CIPOPEN=0,"TCP","cloudsocket.hologram.io",9999
I close and reopen a network PDP session between each of these commands. I am also able to surf the net from the connected raspberry pi, so i know the modem connectivity is good. (the SIM7600 is the only network connection)
I have tried starting over with AT&F.
The results of AT+CGDCONT? are
+CGDCONT: 1,"IP","hologram","0.0.0.0",0,0,0,0
+CGDCONT: 2,"IPV4V6","ims","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0
+CGDCONT: 3,"IPV4V6","","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,1
+CGDCONT: 4,"IPV4V6","","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0
+CGDCONT: 5,"IPV4V6","","0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0",0,0,0,0
+CGDCONT: 6,"IP","hologram","0.0.0.0",0,0,0,0
Thanks again!
