https://devzone.nordicsemi.com/f/nordic-q-a/52205/thingy91-firmwareI 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 &quot;thingy91_ltem_v0.2.2.hex&quot; the default firmware Thingy91 was shipped withen-USTelligent Community 13Wed, 18 Sep 2019 13:25:23 GMThttps://devzone.nordicsemi.com/thread/210426?ContentTypeID=1Wed, 18 Sep 2019 13:25:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1d962857-e204-4ad0-bffa-69b43d1aa578Didrik Rokhaug<p>Hi.</p> <p>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: <a href="https://www.nordicsemi.com/Software-and-Tools/Prototyping-platforms/Nordic-Thingy-91/Download#infotabs">https://www.nordicsemi.com/Software-and-Tools/Prototyping-platforms/Nordic-Thingy-91/Download#infotabs</a></p> <p>1. Yes, that is the default firmware.</p> <p>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:</p> <p><a href="https://devzone.nordicsemi.com/f/nordic-q-a/49650/asset_tracker-does-not-work-with-firmware-v1-0-0/209761#209761">https://devzone.nordicsemi.com/f/nordic-q-a/49650/asset_tracker-does-not-work-with-firmware-v1-0-0/209761#209761</a> </p> <p>The comment above deprecates this comment, but it still has some useful information:<br /><a href="https://devzone.nordicsemi.com/f/nordic-q-a/49650/asset_tracker-does-not-work-with-firmware-v1-0-0/200311#200311">https://devzone.nordicsemi.com/f/nordic-q-a/49650/asset_tracker-does-not-work-with-firmware-v1-0-0/200311#200311</a></p> <p>If you are not able to get it to work following those two comments you should open a <strong>private</strong> case where you provide the IMEI and PIN of the Thingy.</p> <p>Best regards,</p> <p>Didrik</p><div style="clear:both;"></div>
