USB on Thingy:91

Hi Markus,

I think I understand my problem now - I used the list of suggested files from the "Add file" menu (if you have a long path you cannot see important part of the path). Looking now at the list I see that I took the Connectivity Bridge from ../img_fota_dfu_hex/ and the Asset Tracker app from the ../img_app_bl/. So I missed to upload the bootloader to the nRF52 :-(

Best regards,

Hello Laurits,

[quote user="Laurits"]This is really strange - it worked?! [/quote]

Ok, nice! I’m glad to hear that it resolved your issue :-)

[quote user="Laurits"]As you suggested I build the latest version of the Connectivity Bridge firmware, but I am surprised the pre-build hex files I downloaded did not work. [/quote]

I have just flashed the latest pre-complied Connectivity bridge firmware image to my Thingy:91, and everything works as expected. However, my Thingy is of revision 1.4.0. It shouldn’t matter in this case, but anyway.

Which folder in the firmware package did you choose the Connectivity bridge from? Since I’m using the nRF9160 DK as external debug probe to flash my Thingy:91, I selected the image ../img_app_bl/ thingy91_nrf52_connectivity_bridge_2022-06-02_880c82db.hex.

Cheers,

Markus

Hello Laurits,

[quote user="Laurits"]

Right now I have the latest version of the Connectivity Bridge flashed into the device, but I also tried an older version ... just for troubleshooting.

The Thingy:91 is PCA20035, version 1.5.0 (2021.3)

Ok thanks, that should be fine :-) Could you try compiling the Connectivity bridge yourself and flashing it to the nRF52840 using the nRF9160 DK?

Cheers,

Markus

Hei Laurits,

[quote user=""]Now the USB has worked few days ago, tried with different cable (but USB port/cable works fine with nRF9160). I looked in Device Manager Win10 during connection of Thingy:91, but nothing shows up. Any idea how I can continue troubleshoot?[/quote]

Now, that is indeed a strange behaviour. I assume that you flashed the Connectivity bridge firmware image included in the latest application and modem firmware package, 2022-06-02_880c82db?

Which version of the Thingy:91 are you operating with?

Regards,

Markus
