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 used both methods. First I worked with Thingy using Android app and application suggested to update original version to 1.1.0. I try to update and DFU process finished successfully, but Application did not connect to device after updating. Then I try to flash the firmware Thingy:52-HEX 1.1.0 using programmer J-Link and nRF-Go Studio. Thingy device didn't advertise. I think the problem is in firmware.
