Thingy:53 is no more detectable via BLE

[adamsanta]

Hello,

I recently ordered a Thingy:53.

The first time I turned it on, I successfully tried the Edge Impulse app, and updated the Thingy:53 network and app firmware via BLE thanks to the nRF programmer android app.

Then I tried to update the firmware through USB with nRF programmer Desktop on Windows following the instructions at https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/ug_thingy53_gs.html.

I got everything as described at this link, but now, I can't detect my Thingy:53 with any nRF BLE android app anymore.

I have activated the verbose mode on Windows nRF programmer Desktop and I have been able to catch these error messages:

I have seen that other users have experiences a similar issue but I have not been able to find a solution (I know about the SW2 manipulation).

Anyone can help me ? Thanks in advance :)

Hi,

Which application firmware image did you use? There is a precompiled application firmware that can be found in Thingy53 Downloads section.

Hello,

Thanks for your answer Dejan.

I have used the link you attached.

In the 2022-08-03 version, I have especially tried:

Edge_impulse

Peripheral_LBS

Peripheral_UART

Bluetooth_Mesh light switch.

For each one, nRF programmer on Windows 11 seems to tell me the programming went OK.

For some of them, I got the LED flashing, but I never succeed in detecting my Thingy via BLE...

Hi,

I have asked internally about the possible reasons for the error that you reported. I'll get back to you when I get new information, possibly till the end of this week.

Hi,

Which versions of the Windows operating system and Thingy53 did you use when you got errors?

Did you connect through USB hub?

Best regards,

Hi Dejan,

I am using:
- Windows 11 version 21H2 (I had a similar issue on Linux Parrot OS)
- Thingy:53 1.0.0 2022.35 (bought from Farnell 2 weeks ago)
- Precompiled firmware: 2022-08-03-precompiled-application-firmware
- nrf-device-lib-js version: 0.4.13
- nrf-device-lib version: 0.12.8
- nrfjprog DLL version: 10.16.0
- JLink version: JLink_V7.66a

I am not using any USB hub, I am connecting directly on my laptop.

Thanks,

Adam

Hi Adam,

It might be useful to see if there are any differences regarding your issue when you use Windows 10 instead of Windows 11. Could you try with Windows 10?  Are there any error messages in that case?

Hi Dejan,

I just tried with Windows 10 21H2. The error messages are the same : "delete package error 8" + "serial io_context handlers executing".

I had also the same messages on Parrot OS Linux.

I have fond a way to program my thingy53 with an external probe (so without using mcuboot).

After flashing this way (via Visual Studio), I have been able to detect again my thingy53 with Android nRF connect so it seems the problem was solved.

But then, when I did the test with Windows 10, my thingy53 was again invisible for BLE + application not doing what it is supposed to do.

Very strange.

Thanks,

Adam

Hi Adam,

Was the Thingy53 device visible in the nRF Connect Android app after you successfully flashed it?

Hi Dejan,

When I use an external probe, I see my device on nRF Connect Android.

If after this success, I try to update the firmware through MCUboot with nRF programmer Windows, I don't see it anymore. While nRF programmer still told me that the update was successful.

Best regards,

Adam

Hi Adam,

We have tested updating the firmware through MCUBoot on both Windows 10 and Windows 11. The device was in both cases visible in the nRF Connect Android application after the update.

I am experiencing the exact issue as adamsanta . Same debug print as well.

Hi Erick,

Could you describe your setup? 
What is your Thingy53 version?

Best regards,
Dejan
