Hello Øyvind,

Thank you for your help! I was able to get the connectivity bridge updated on the device, and subsequently the modern flashed.

Cheers,

John

Hi John,

Please see this guide. As stated in the CONTENTS.txt in the precompiled folder.

img_fota_dfu_hex/     Application only. Use with nRFConnect for Desktop Programmer application.

Now use SW4 to start the nRF52 device in serial recovery mode and connect to it using the programmer app in nRF connect for Desktop. Here you can choose the img_fota_dfu_hex/thingy91_nrf52_connectivity_bridge_2021-03-04_8e8c6089.hex and program the device.

Please do not use the update modem.

Kind regards,
Øyvind

Hello,

Thank you for your response.

Looking through the precomplie files these were the files I found relating to connectivity bridge:

img_fota_dfu_hex/thingy91_nrf52_connectivity_bridge_2021-03-04_8e8c6089.hex

img_fota_dfu_bin/thingy91_nrf52_connectivity_bridge_2021-03-04_8e8c6089.bin

img_app_bl/thingy91_nrf52_connectivity_bridge_2021-03-04_8e8c6089.hex

I don't think I can use the .hex files - and the .bin file wasn't a viable option when I tried to load it after selecting "update modem". I then zip'ed the .bin file and tried to use it to update the modem. It began to write, and then the nrf connect programmer went to a white screen. I waited a while and reloaded and nothing has changed.

I'm missing something here? the connectivity_bridge is updated via the "update modem" option in the nrF connect programmer right?

Thank you for your time.

Cheers,

John

Hello,

[quote user=""]Following this, I am no longer able to boot my thingy91 into serial recovery mode using SW3 however I still can with SW4 which I am reading is only for flashing nrf52... things rights?[/quote]

It sounds like you need to update the connectivity bridge on your nRF52. In the precompiled firmware package, found in the Thingy:91 download section, you'll find a precompiled version (based on NCS v1.5.1) of the connectivity bridge to program on the nRF52 (SW4).

Please update and let me know if that helps with the communication to the nRF91.

Kind regards,
Øyvind
