DFU not working on Thingy

[HarryO]

Using the Thingy app on Android, when I connect to the Thingy, it says 'Firmware Update ...'. I click on confirm, come in the Firmware Update screen, click on the blue button at the bottom right, nothing happens.

Similar with the Thingy app on an iPad, on the Firmware Update page, when I click on Start at the top right, a spinner is shown to the right of DFU STATUS, Enabling bootloader is unmuted, and then nothing happens anymore.

How to update the firmware?

[Simon]

Take a look at this case, and Joakim's answer. It seems like Firmware Update doesn't work using the Thingy app, and you need a programmer to do it.

Please let me know if you have more questions.

Best regards,

Hi Simon,

Thanks for the response. I saw the other case, but I am not aware that I had a custom ANT firmware. Besides, the link to the nRFgo Studio is not working.

Is it not possible to update the firmware without buying an additional piece of hardware?

Kind regards,

Harry

I was too quick to answer, in the case I referred to, the customer had a Thingy without the correct firmware. If you have bought a brand new Thingy, this shouldn't be an issue. It should have the correct firmware, and Firmware Update should be possible. Where did you get your Thingy? Has anybody used it before you? Then there is a possibility that some other Firmware is flashed onto the chip.

Initially I encountered the same issue as you, I used the firmware from github, and wasn't able to perform the Firmware Update for some reason. However, if I flashed the hex file provided in this link, it worked all fine.

OK, so how do I flash that file?

[Simon]

In order to flash a file onto the Thingy, you would need a programmer. The Thingy does not come with with one, but you can use the programmer of an nRF52 DK. Take a look at this case for an explanations on how to do it.

Best regards,

Simon
