Hi,

I have the old Thingy:91 v1.0.0, which modem firmware and application I should download?

Thank you.

Hello Suttichai,

That depends a little bit on what you would like to do, but in general I would recommend you to use the latest pre-compiled application and modem firmware.

Depending on how you would like to program your Thingy:91 (MCUboot or via an external debug probe), you can choose between different application images located in those two folders:

Folder contents:

img_app_bl/
- Full application images including bootloader.
- These files can be used with:
- nRF Connect Programmer (only with SEGGER J-Link or another debug probe)
- nrfjprog CLI

img_fota_dfu_hex/
- These images contain only application and bootloader is not included.
- Images are in HEX format.
- These files can be used with nRF Connect Programmer (only via USB bootloader).

Please note that the Connectivity bridge firmware image on the nRF52840 only can be updated using an external debug probe for your hardware revision, as mentioned here.

Regards,

Markus
