AT&T IoT Starter Kit|Getting the SIM to active status?

I'm having the same issue.

When I run the Jasper diagnostics, suggestion is that APN could be the problem. But I don't know if that's something that we can access in the Avnet board.

The APN was set for me in the cisco jasper interface. If you login to the simcontroller.wireless.att.com site. Select "devices", then select the ICCID of the SIM you're using in the table presented, then select the spotlight tab - when this view presents the SIM info the APN address is listed there. 

As far as I can tell however that field is not editable. So the troubleshooting step would be helpful if it provided instructions for how to set it. 

Are you able to see the activity over your serial port (aka USB port) after you've run the att quickstart binary? Do you see the modem attempt to initialize but fail?

I can also see the APN in jasper - m2m.com.attz

But the device must have this also. I thought it might be configured in the Avnet board, but I have now looked through the quickstart mbed source and found that it's in the mbed program (in config_me.h). It appears to be set correctly, so that's not the problem.

I can see activity via USB-serial, also seeing output that says modem initialization has failed.

Anybody from ATT&T reading this? Would be nice to get some help. I tried a support ticket, but no contact yet, also can't even see if a ticket has been created.

The live chat on the starterkit.att.com web site usually gets a better response, though this may involve Cisco or just sending you a new SIM.

Just making sure: you did change the status from "Test Ready" to "Activated" in the starterkit.att.com/app/sim-cards interface?

You'll also want to make sure that the modem is properly powered and you may need to use the diveristy antenna in addition to the primary one.

Let me know.
