Arduino SDK-c Code: -2 Error
carbonbasedrobot opened this issue · 4 comments
I am following the steps of this github: https://github.com/Azure/azure-sdk-for-c-arduino/blob/main/examples/Azure_IoT_Hub_Arduino_Nano_RP2040_Connect/README.md
to upload the example sketch Azure_IoT_Hub_Arduino_Nano_RP2040_Connect
I've followed every step carefully, have downloaded everything I've been told to download and imported all necessary libraries. I correctly input my hotspot network ssid and password, as well as the relevant Azure IoT resource group, device id and primary key info but when upload the sketch, I get the following error (with blurred out sensitive info ofc):

I have been unable to identify what the issue is, and havent seen this error anywhere on google. What should I try?
Thanks, I'm getting desperate
Hello!
Since you mentioned Azure IoT resource group, for your IOT_CONFIG_IOTHUB_FQDN, are you using the hostname?
And the primary key from your device page?
Hi @carbonbasedrobot, I successfully ran the sample, wanted to check if you've taken a look at @vaavva's comment above. Another good thing to check would be if you've installed the latest Arduino libraries.
