C030-R412M Eval Board Cell Connection

Mbed OS Hello world!

Hi, I’m trying to evaluate Mbed and Pelion using the C030-R412M eval board. I have started with the “mbed-os-example-pelion” program and simply modified the json with my APN:

        "nsapi.default-cellular-apn"                : "\"iot0119.com.attz\"",
        "nsapi.default-cellular-sim-pin"            : null,
        "nsapi.default-cellular-username"           : null,
        "nsapi.default-cellular-password"           : null

It compiles and runs, but it hangs on the cell connection. Here is the serial sniffer log:
AT+CFUN=4
OK
+CREG: 0
+CGREG: 0
ATE0
OK
OK
OK
OK
OK
+CPIN: READY
OK
+COPS: 0
OK
OK
OK
+CGACT: 1,0
OK
+CGATT: 0
OK
OK
+CSQ: 99,99
OK
+CSQ: 99,99
OK
+CGREG: 2,4
OK
+COPS: 0
OK
+CREG: 2
+CGREG: 2
+CSQ: 99,99
OK
+CGREG: 2,4
OK

If I manually send the following cmds to the ublox modem, it seems to find available connections:
AT+CGDCONT=1,“IP”,“iot0119.com.attz”
AT+COPS=?
+COPS: (1,“AT&T”,“AT&T”,“310410”,7),(3,“313 100”,“313 100”,“313100”,7),(3,“311 480”,“311 480”,“311480”,7),(1,“310 260”,“310 260”,“310260”,0),(3,“311 480”,“311 480”,“311480”,9),(1,“AT&T”,“AT&T”,“310410”,9),(1,“310 260”,“310 260”,“310260”,9),(0,1,2,3,4),(0,1,2)

What am I missing in the “mbed-os-example-pelion” configuration?

Thanks for your help.

This board and example should work. Are you able to confirm that your sim card is active and compatible with the network type supported by this module, and available networks?
