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).

I'm able to put it in bootloader mode and upload new firmware to it. The process ends by displaying "completed" in the app, but after a few seconds the light on the device turns off and I can't find it anymore. I've tried looking for it with both the Thingy app and nRF Connect app. In the nRF Connect app I see my MacBook, my headphones, some neighbours ChromeCast and a lot of N/A devices.
