PSK ID and PSK are lost after the reboot of my hardware

[Salem L]

Hello,

I am currently developing a product that is based on a nrf9160 and more precisely with a Thingy:91, this project integrates the tools of Golioth to communication data. And I am encountering a little issue with my PSK and PSK-ID registration. I wanted to communicate my PSK and PSK-ID by UART and I managed to do it, now the problem is that even tho it's telling me that the keys are correctly saved when i reboot my device it doesn't load them automatically and it doesn't reconnect to my Golioth space anymore. I've followed the advices that are listed in Golioth's github but didn't find anything that seemed like my issue there and in the other forums.

Thank you for you help.

Best regards,

Hello, 

Are you able to provide more details on the issue you are seeing? I'm not familiar with the Golioth solution. Could you provide me the link to the Github that you are referring to?

What version of the nRF Connect SDK are you developing with, and what modem FW are you running on your nRF9160?

A modem trace could provide some answers, along with the modem logs. 

Thank you. 

Kind regards,
Øyvind

Hello,

I am using the Golioth solution, a firmware that bridges my device and their platform, allowing me to manage my IoT devices. For the connection, I am using Golioth's firmware with Zephyr. Here is the link to the firmware:https://github.com/golioth/golioth-firmware-sdk/tree/main

Regarding the PSK parameters, here is a link with detailed instructions that I followed: LINK TO THE GOLIOTH README EXPLAINING THE PROCESS TO FOLLOW

I am using version v2.5.2 of the nRF Connect SDK. The connectivity is not an issue as my LTE-M modem connects well. The problem is saving the PSK keys upon reboot.

Thank you for your help in resolving this issue.

Kind regards,

Salem.

Hi Salem, 

I have no knowledge about the Golioth SDK. Please contact the Golioth community for more support regarding their applications.

Hello,

Thank you for your help. The issue I was facing was due to an erase operation in the flash memory, which was being done in another part of my code.

Thanks again and have a nice day.
