These are the error codes when compiling. I can change the source code, but I rather have someone more familiar looking at it.

I'm using a MKR NB 1500 bought last month & Arduino IDE 2.2.1.

Hi @Jorin-Post what example are you trying to build?

[Jorin-Post]

@pennam The Azure IoT Hub NB. When I use the old libraries the code does upload.

• #include <ArduinoBearSSL.h> // 1.2.0
• #include <ArduinoECCX08.h> // 1.2.0
• #include <utility/ECCX08SelfSignedCert.h>
• #include <ArduinoMqttClient.h> // 0.1.0
• #include <MKRNB.h> // 1.3.1

So problem solved sort of.

There is always a next question.. Do you know if I need to fill in my ANP somewhere? Now I get the return

AT+CEREG?
+CEREG: 0,2

From other modems I know I needed to fill in my ANP to get connected.

That is strange, i'm able to build without issues using this libraries:

Using library ArduinoBearSSL at version 1.7.3
Using library ArduinoECCX08 at version 1.3.7
Using library Wire at version 1.0
Using library ArduinoMqttClient at version 0.1.7
Using library MKRNB at version 1.6.0

Do you know if I need to fill in my ANP somewhere?

I would say yes, you can configure the APN changing this line https://github.com/arduino/ArduinoCloudProviderExamples/blob/4ce13b8f37d3059aca7dd791b2ee9ba496921394/examples/Azure%20IoT%20Hub/Azure_IoT_Hub_NB/Azure_IoT_Hub_NB.ino#L117
