Thingy91 - start-up problem will not connect to LTE - please help :-)

sorry for the perhaps stupid question - but despite several hours of intensive searching, I am not getting any further with the start -up of my new and beautiful Thingy91.
Unpacked and proceeded exactly according to the get started video ( https://www.nordicsemi.com/Software-and-tools/Prototyping-platforms/Nordic-Thingy-91/GetStarted#infotabs) -   Updating Zip file 2021-03-04  downloaded  - Modem firmware updated and Asset Tracker - Hex (thingy91_ltem_2021-03-04_8e8c6089.hex) for LTE installed. Everything worked.
SIM card activated and now the problem - no LTE connection - even though I am trying for hours in the middle of Germany with a well-developed LTE network. The LTE Link Monitor shows Connecting to LTE network - but then LTE could not be established .. Question: was that the correct hex file for the LTE asset tracker? Or where is my mistake?
Thanks in advance and stay healthy

  • Hi!

    How did you update the FW - via MCUboot or a debug probe? And which folder did you get the .hex file from (img_app_bl or img_fota_dfu_hex)?

  • I uploaded via MCUboot (as shown in your video) and the hex file was out of img_fota-dfu_hex.

    Any ideas ????

    Update  Saturday 21:50

    I used the last days to organize a TELEKOM Germany LTE Simcard.  Before inserting I  updated the Thingy one more time  with Zip file 2021-03-04   - Modem firmware updated and Asset Tracker - Hex (thingy91_ltem_2021-03-04_8e8c6089.hex/ out of dircetory :" img_app_bl or img_fota_dfu_hex"  to be sure that there are in the mean time no changes in the firmware.   

    Result :  with the TELEKOM Simcard  there was a quick conection to the LTE :-)   but unfortunately "Failed to connect to cloud, error -3[0m"  and finally [UART FRAMING ERROR! CHECK BAUDRATE!]  :-(

    same test with the IBASIS -Simcard provided with the Thingy  resulted in " Failed to estabish LTE Connection". :-(

    I archived the log files for these two tests  - so if you need them - please short message or better e-mail and I will send them -  actually I don't know  how to attach them in this helpdesk tool.

    By the way : I wonder  how it's possible to enter the market  with such an "Out of the Box IOT- Device".  Isn't there  no pre-test phase with some not quite so qualified users. You put in a lot of effort with start-up videos, documentation, ... but if you look at the number of tickets, you can see - it's sometimes not so easy and that of course tarnishes the joy of such a high- tec device in which there is so much sweat and effort of so many Nordic employees. I am happy to offer myself as a "dumb tester" for future products :-).

    So I hope to be able to support the troubleshooting. What else can I do to get the thingy up and running?   I hope you had a nice and relaxing weekend ...

  • Hi!

    I'd love to take a look at the logs. You can click "Insert" -> "Image/video/file" and attach the logs in your next comment.

    Unfortunately, development for these devices moves so fast that when a device is bought the FW that it came shipped with is usually outdated, which is why we recommend updating the FW before getting started. 

  • Hallo Heidi,

    attached are the two logfiles and yes : I updated the FW before starting this adventure :-)
