STEVAL-STWINK1 Bluetooth connection problems

[TResell]

Hi. I just bought the new STEVAL-STWINK1 eval board and tried it out on the ST BLE android app. But i keep getting connection errors on the bluetooth and get disconnected.. I can barely finish one FFT analysis before the bluetooth bugs out and disconnects me. Do i need to reflash the firmware on it? And if so, where and how do i do so?

I checked the firmware version in the app and it is version 2.1.0

Hi @TResell​ , I don't think it is a FW-related issue, but maybe a BLE communication from smartphone app side. Btw, it make of course sense to try to fix the issue by reflashing the FW: you can find it in the STEVAL-STWINKT1 function pack, folder \Projects\BLE_SampleApp\Binary (or here attached). I suggest you to use the STM32CubeProgrammer software together with the STLink-V3Mini Debugger/Programmer for STM32 for the reflash procedure. Regards
