EM7565 development kit on windows 10, Can't connect to this network, Cellular data isn't working properly

I am trying the EM7565 development kit on windows 10. I have ATT SIMS activated through Sierra. I am getting an error when I try to connect, “Can’t connect to this network” “Cellular data isn’t working properly. Try again later.”

I am powering my device off of a powered USB switch and I have both of the provided antennas connected along with the short cables to connect the radio ports to the devkit board’s ports.

Anyone have any ideas? I have installed the firmware noted for ATT at https://source.sierrawireless.com/resources/airprime/minicard/75xx/airprime-em_mc75xx-approved-fw-packages/#sthash.YQLOVVFZ.dpbs .

Do you have modem port in device manager?

I believe so:

What is the return of followings on modem port?

At!entercnd=“A710”
At+cpin?
At!impref?
At!gstatus?
At+cfun?

It turned out I needed an APN. Now that I have that, I can connect but I can’t get a DNS server. I also can’t ping the gateway.

To send AT commands, I assume I connect to the DM Port above (happens to be COM12 on my system). Is it 9600 8n1 with no hardware flow control? I tried that with PuTTY with no luck.

Not dm port, it should be modem port for AT commad

It shows me as connected but no data has been received.

I also have no data sessions in the app.

Is your sim card working fine?

Thank you for your help so far.

The SIM question is a good question. I can send but I can’t receive anything. I can get the app to track sessions but it also shows no data received.

Do you know SIM diagnostic commands that I can run?

You need to consult network provider
