Thingy:52-HEX version 1.1.0 doesn't work

[kchuva]

Hi,

I have the Nordic Thingy:52 (PCA20020 1.0.0 2017.19). It worked well until I downloaded new version of firmware 1.1.0 and updated Thingy. After that I didn't see advertising packets from Thingy.

Then I flashed into chip some peripheral example and Thingy appeared in radio space. Thus chip is works. But software Thingy:52 v.1.1.0 isn't work well.

Has anybody the same problem?

P.S. Update 23.07.2018

I did debug Thingy software and found reasong of incorrect behaviour.

The problem was in SAADC module. SAADC always returns 0xFF values so battery measurement was failed. Because of that failure the M_BATT_MEAS_EVENT_LOW was raised and software shutdown Thingy at m_batt_meas_handler function (main.c).

having the same issue with a (PCA20020 1.0.0 2017.20). oddly enough it appeared that mine flashed correctly, but then a day later decided to hit the wall and is just flashing red. trying to push 1.1.0 again doesn't work.

all via the iOS app - downloaded firmware size on the app is 154,898 bytes, but when downloading to computer it is 159,265 bytes. so possibly it's not running a checksum against it after an incomplete download?

without a devkit setup i guess i need to retrieve the 1.0.0 firmware to push via the iOS app to get this operational again. does someone have a link to that? scouring google didn't yield it due to the way nordic "encodes" their download links and only makes 1.1.0 available for download.

Hi siivv,

• Are you able to find the Thingy using nRF-Connect?
• Is the Thingy charged?
• Could you try to use nRF Connect to flash the thingy? You can download the 1.1.0 firmware package from here. Put the Thingy in bootloader mode(hold the button down while powering it up), and use nRF Connect to do DFU.

ahh, naive on my part, i didn't realize there was non-mobile software package. fantastic. i will try this evening

unfortunately the windows version requires the devkit to be connected, so that's a no go. also, i tried the nrfconnect app on my phone and that results in the same outcome. i tried on another phone as well thinking it was my phone, but no luck with that either.

at this point i think i'm going to RMA the device as it is strange that it worked without issue for a couple days and then hit a full stop and now cannot be flashed with the nordic provided ios app & firmware
