NB-IoT network and DNS
Is it possible to do a DNS query using the NB-IoT sim card (starter kit)?
All my DNS queries fail, however the module I’m using works fine when calling the UDP server using the static IP address.
@Artur-S I don’t think so. And since your device can’t access open internet anyway it doesn’t make much sense to do it. Interested to hear why you need DNS
Ok that makes sense, so the starter kit is limited only to the internal T-Mobile network? I didn’t know it’s not capable of accessing the global internet.
My point was to have the NB-IoT device sending data directly to my API endpoint, without proxying data through the platform API and then forwarding to my final endpoint.
@Artur-S As far as I am aware all NB-IoT connections are limited to the internal network only. The only reachable endpoint is the CDP so reaching your API endpoint directly is not possible. Maybe that LTE-M does offer this option. Someone from T-Mobile can comment on this :)
Hi @Artur-S ,
@Stefan-de-Lange is correct public DNS is not reachable from the IoT creators sim cards. I didn’t see and DNS option available in NB-IOT only capable modems I must say. Indeed LTE-M gives access to public DNS and internet. You could try one of the prepaid cards some of the T-Mobile operators are offering for IoT.
