Unable to flash Thingy91 modem

I'm trying to get Thingy91 works under either Mac OS or Linux. Neither of Programmer nor LTE Link Monitor doesn't work. Programmer complains about that device is not in MCU mode, LTE Link Monitor do not get any response from the port. I've tried to hold SW3 before switching Thingy on. I saw MCUBOOT USB device in the list, but dfu-util doesn't report any compatible devices. Same for Linux. I've tried to power cycle and hold SW3 many times.

The only way when the Programmer and Monitor works is under Windows. With the first attempt I was able to update firmware & use LTE Monitor.

How to get BLE work? I've updated Config.txt file on the flash to enable BLE, but after power cycling it still not available under BLE tool: it reports operation timeout when attempting to communicate to BLE device even under Windows.

PS. I use the most recent nRF Connect v3.5.0. Tried with Mac OS 10.15.7 and Ubuntu 20.04.

Hello Amine,

Glad to hear that you were able to program the modem using the latest version of the Programmer app (v1.4.4).

There is no available command-line interface, however, you could try with a python script as my colleague Sigurd suggests.

Kind regards,
Øyvind

Hello Øyvind, sorry for the late response.

My Thingy91 version is 1.0.2 2020.13.

I tried flashing using nRF Connect Programmer v1.4.4 and it works perfectly fine (after 2 tries).

Is there another way to flash the modem or the firmware using Command Line?

Best regards,

Amine

Hello again, I'm currently working with the developer of nRF Connect Programmer. Can you please provide the version number of the Thingy:91?

Also, there is an update to nRF Connect Programmer that should fix the issue. Can you please try that?

Hello,

Sorry, I have not been able to get in touch with our developers. Can you please try with nRF Connect for Desktop vs 3.3.0 to see if this can solve anything?

Kind regards,
Øyvind
