APN locked to specific IP
Is iotcreators.com SIM card locked just for accessing specific IP adresses? I am unable to connect or resolve DNS names with APN cdp.iot.t-mobile.nl
Quectel BC-660K reports network attached, IP assigned but I can not get dns name resolved, or NTP synchronized, etc, even though AT+QIDNSCFG=0,“220.127.116.11”,“18.104.22.168” is OK.
when using APN cdp.iot.t-mobile.nl you can indeed only access our servers via 172.27.131.100. We have different servers available: MQTT, UDP, CoAP, LWM2M and NON-IP.
By using on of our services you will be able to get your device data in your preferred platform via webhook (http/callback).
when using APN m2m.public.nl you can send data to any IP destination on the public internet.
@afzal_m Thank you very much for explanation. I am now in the process of learning AT commands and sometimes it is hard to recognize what non-functionality is intended or just my fault…
One day you will have dreams about AT-commands
