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 could not reproduce the issue which you reported. Everything went as expected for me. However, I can provide several suggestions to you. 
    In order to program Thingy53, you would need to be in the bootloader mode. This is achieved by pressing SW2. Please make sure that you press button SW2 on the Thingy53 and not some other button. When you program applications using updating through USB mode, the name of your device will change. Therefore, when you scan for your Thingy53 (for this you can use nRF Connect Android app), it will appear with different names, such as "EdgeImpulse" if flashed with Edge Impulse zip, "EI Thingy53" if it is flashed with Machine Learning zip file, or "Nordic_LBS" if it is flashed with Peripheral_LBS zip file. You should be able to see your Thingy53 device if you followed the procedure correctly and if you scan for the device with a proper name.

    Best regards,
    Dejan
