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).

Hi,

Version 1.1.0 works fine here. How did you update the Thingy:52? Did you use DFU using the Thingy smartphone app? or did you you flash the firmware using a programmer/debugger?

[kchuva]

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.

Are you able to find the device using nRFConnect? Also make sure that it's awake(press the button on the top).

In nRFGo studio, it should look like this:

No, I'm not able to find the device using nRFConnect if I flashed Thingy-HEX. But if I flased another firmware, the device will become available for connection. Of course, I try to press the button and switch power off/on.

I don't know how to insert image, but i have the same picture in nRFGo Studio as you have.

Try to download the Thingy-hex-1.1.0 from here. Use nRFGo Studio to "Erase All", and then program the hex using the "Program Application" tab in nRFGo Studio. After it have been programmed successfully it should start advertising.
