Failed DNS lookup for my-test.azure-devices.net: 202 #120

Closed kedzior-io closed 2 years ago

kedzior-io commented 3 years ago

Follow up from https://github.com/Xinyuan-LilyGO/LilyGO-T-SIM7000G/issues/114

I'm using the Azure IOT example as is.

https://github.com/Xinyuan-LilyGO/LilyGO-T-SIM7000G/blob/master/examples/Arduino_Azure_IoTHub/Arduino_Azure_IoTHub.ino

What I get is:

Failed DNS lookup for my-test.azure-devices.net: 202

Mr-HaleYa commented 3 years ago

No serial log??? No sketch example??? you just expect us to know what this means???

Failed DNS lookup for my-test.azure-devices.net: 202

@Mr-HaleYa

LilyGO commented 3 years ago

Hello, have you solved your issues?

kedzior-io commented 3 years ago

@LilyGO nope. I invested a lot of time into it and finally I gave up and used different board that can run node-red.

LilyGO commented 3 years ago

Can you run this [example] (https://github.com/Xinyuan-LilyGO/LilyGO-T-SIM7000G/tree/master/examples/Arduino_TinyGSM/AllFunctions) properly ?

kedzior-io commented 3 years ago

@LilyGO thanks ,I will give it a go this weekend.

kedzior-io commented 3 years ago

@LilyGO

It seems it connects OK. though the issue is DNS.

I have exactly the same problem. First I tried to solve the problem with SNTP and set the time with the help of #https://github.com/vshymanskyy/TinyGSM/issues/357#issuecomment-973873741. After that I had the next error:

Rebooting...

When I use Wifi.Begin(), I also get the message: Failed DNS lookup for xy.azure-devices.net: 202

Can it be that when trying out the example, a WLAN and password were set in the code and it only worked via the WLAN?

kedzior-io commented 2 years ago

@raphac , @LilyGO , @lewisxhe I'm closing this issue. I complete gave up on Azure IOT Hub. I also have found issues using other boards. Switched to my own hosted MQTT broker (https://mosquitto.org/) and the device works very smoothly.
