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.
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.
OK

I’m trying to establish data connection with my EM7565 on window 10 but having similar issue as well. I don’t have the GSM antenna installed yet but the AT!SCACT =1,1 return error. It seemed like the data network cant be turned on in window.
