Failed to generate JWT

Hi,

To build the Location sample with P-GPS support, use the -DOVERLAY_CONFIG=overlay-pgps.conf option. For example:

west build -p -b nrf9160dk_nrf9160_ns -- -DOVERLAY_CONFIG=overlay-pgps.conf

See Providing CMake options for more instructions on how to add this option.

If it cannot fix the issue, please create a new support case for the new issue. This is away from the original scope.

Thanks, Amanda,

I've tried to update the modem to the last version 1.31 and generate a new certification and make the provisioning again.

It was very complicated to generate new keys and assign the public key to nrfcloud. And besides that, it didn't work by GUI of the website (NRFcloud ) to assign the public key so I had to use REST API to assign the public key of thingy91.

Finally, the Jwt-error doesn't appear anymore but now it seems that the GNSS methods don't work in the Location sample and only Cellular works fine, is there anything else I need to do to get AGPS/PGPS working fine? or is there any easy way to test AGPS/PGPS of nrfcloud with thingy91 without those complications :)?

Hi,

Please update Update Certificates as this documentation https://docs.nrfcloud.com/Guides/GettingStarted/Devices/#securely-generating-credentials-on-the-nrf9160

What is the modem firmware version? The latest version is v1.3.1 here.

Regards,
Amanda

UPDATE:

I've also tried the Location sample of SDK1.8 and I got this output:
