That is good to hear. Did you try issuing AT%XEPCO=0 to see if DNS worked then?

Kind regards,

Hi,

If you connect using the IP directly, you are able to do so successfully?

If that is successful, the issue is most likely that the network does not provide DNS. You can try to enable legacy PCO using this AT command:

https://infocenter.nordicsemi.com/topic/ref_at_commands/REF/at_commands/packet_domain/xepco_set.html?cp=2_1_6_12_0

ie:

AT%XEPCO=0

Note that this shall be issued before AT+CFUN=1.

Kind regards,

Håkon

Ok, thats fine. Next time, just write "example.com" or similar.

Does the CEREG notifications come after you have issued XCONNECT? If the order is correct here, then the "CEREG: 1, .." comes after you tried to connect, meaning that you haven't properly connected to the network at the time of trying to access the URL.

Kind regards,

Håkon

Hi,

[quote user=""]AT#XCONNECT="runner.daigou52.cn",8282[/quote]

This domain does not exist when I tried to do a nslookup on it. Are you sure you've written the correct domain name?

Kind regards,

Håkon
