Failure in creating device certificate & provisioning it

[PKK]

I am creating device certificate as per steps mentioned at 

https://nordicsemiconductor.github.io/asset-tracker-cloud-docs/saga/docs/azure/GettingStarted/DeviceCredentials.html

Create root & intermediate certificates works fine, 

But when we issue 

node cli create-and-provision-device-cert

to create device certificate & provision it, it results in failure as follows:

node cli create-and-provision-device-cert --dk --debug --delete-private-key
Flasing certificate /dev/ttyACM0
Connecting to /dev/ttyACM0
Inactivity timeout 10 seconds
ERROR create-and-provision-device-cert failed!
ERROR Readline is not a constructor

Using Ubunto 20.x lts, using asset tracker 1.9x , firmware is created fine, it also works if I generate certificate using microsoft method for testing. 

@oys Let me know if you need more information

Hi Charlie,

I am not sure, what are you askign for, AT commonds work through NRF LTE LINK Monitor fine with current hex file and also with AT_host hex file, but command to generate device certificate fails with same error in both cases. 

Do you think if I give you remote to the system, will it help you ?

using Zypher tool Monitor, we can access the port file, so its only create certificate command which can't read

@charlie-shao Any update ?

[Charlie]

Hi Pramod,

Unfortunately, I did not have any chance to repeat this issue by far, are you able to try this process with a completely new ubuntu installation? Maybe this will help to find some clues.

Best regards,

Charlie

Already did, and also deleted, and did fresh git pull. Are you part of development team ? if so, I am willing to give you remote access to figure out what is happening.
