Firmware Upgrade / Asset Tracking disabling

[Mathieu-S]

Hi Everyone,

I was wondering if it is something I do wrong, or if there is an issue with my module.

I have never managed to successfully upgrade the firmware of my nRF9160 Thingy:91.

I am using the nRF Connect v3.7.1 with the Programmer tool.

I have followed the documentation and tried the SW3 Button + Power Button + Add Hex File method. I have tried the SW4 Button + Power Button + Zip file method

But the upgrade never goes through and I often end up with a message such as "Please make sure that the device is in MCUboot and try again" (depending on the method choosen).

The current firmware version on the Thingy:91 is mfw_nrf9160_1.1.1

My end goal is to disable the AssetTracker entirely (so that it won't Power Cycle when I don't want it to), and I believe that was the only possibility.

Any idea to disable the Asset Tracker would be most welcome !

Cheers,

Mathieu

Hi,

Replying here to myself for the detailled solution : 

SW4 + Power + img_fota_dfu_hex\thingy91_nrf52_connectivity_bridge_2021-06-28_7a076c22.hex

then

SW3 + Power + mfw_nrf9160_1.3.0.zip

then 

SW3 + Power + img_fota_dfu_hex\thingy91_at_client_2021-06-28_7a076c22.hex

With this I ended up with the modem FW 1.3.0 and AT capable device, but with no Asset Tracker.

Testing was much more fluid for my needs.

Cheers all,

Thanks Oyvind for all the support.
