Thingy91 Firmware

[Pritesh]

I updated Thingy91 with modem firmware (mfwnrf9160100.zip) and application firmware (thingy91_ltem_v0.2.2.hex) from latest firmware package (thingy91fwv022.zip).

Question 1: Is "thingy91_ltem_v0.2.2.hex" the default firmware Thingy91 was shipped with?

Question 2: I am seeing Thingy91 rebooting in a loop every few seconds. How can I recover Thingy91 to its default firmware application it was shipped with? I am looking for firmware that send real GPS every two minutes and stays in low power mode most of the time.

Hi.

A new version of the modem firmware has been released (v1.0.1), and you should update. You can find it at the bottom of the downloads here: https://www.nordicsemi.com/Software-and-Tools/Prototyping-platforms/Nordic-Thingy-91/Download#infotabs

1. Yes, that is the default firmware.

2. The cloud_connect error typically means that there is something wrong with the certificates needed to connect to the cloud. Take a look at this comment on how you can get new ones:

The comment above deprecates this comment, but it still has some useful information:

If you are not able to get it to work following those two comments you should open a private case where you provide the IMEI and PIN of the Thingy.

Best regards,
