Hello, I recently bought a sensortile box and I have an issue with it.

[zamlox]

I uploaded accelerometer application from phone application and it worked well. But after a while it stopped working. It didn't connect anymore to phone application. I thought battery was depleted so I charged it for a while but still no connection.

Then I tried to upload a new firmware on it using STM32 JTAG probe but it cannot connect to that either. I'm using STM32CubeProgrammer tool for that and it gives me the error: "Error: No STM32 target found".

From what I can see the sensortile is powered on (no led blinking) abd JTAG cable connected ok.

What can be wrong ?

Thanks.

I suggest you to unplug the battery when you upload the firmware.

Thank you for answer.

After trying several times unplugging usb cable and connecting JTAG I managed to see the device in STM32CubeProgrammer and I was able to upload a new firmware.

Problem solved.
