Cannot create device on AVSystem portal with custom endpoint

Hey,

We are trying to create PoC which includes NordicSemi thingy 91 or nRF9160DK, AVSystem portal and AWS cloud.

By default AVSystem uses string "urn:imei:<imei number>" as device identifier. That works fine but because of issue of AVSystem it doesn't allow to create thing on AWS - because of colon usage.

To avoid that we are trying to create new device with endpoint "urnimei<imei number>" but this is where it doesn't work. Sequence is following:

1. Device was successfully added to AVSystem portal via provision.py script from lwm2m client application and at_client application. Device become visible on AVSystem portal in state bootstrap.

2. Next step - connect device using lwm2m_client application. In order to use updated endpoint following config was added to Pjt.conf file: CONFIG_APP_ENDPOINT_PREFIX="urnimei"

3. On connection terminal shows following:

Unfortunately guys from AVSystem have lack of knowledge with Thingy side.

Can you please suggest how to debug this?

Thanks,

Thanks a lot for your feedback, Mykhaylo!

What I see in it is that endpoint value is changed to my new format "urnimei" instead of "urn:imei:". But Identity value is still "urn:imei:" while I would expect it to be same "urnimei". Is there any way to change Identity value?

I asked one of my colleagues with an active AVSystem account to perform the same steps you did, and he was able to successfully connect to the Coiote server:

He did not use the provision.py script though and performed the steps manually instead. That brought my attention to the script itself. You probably have to update this line as well in the script to make the identity value match:

identity = f'urn:imei:{imei}'

Cheers,
