Hi Ralf

Are you in application development with QT?

This board is something interesting one can do with BLE, ML, and sensors. I have used Nimble from Apache mynewt. It is a portable and fully open-source BLE stack.

I used nRF52840-dongle along with riot-os to interface ble with BME280 sensors...

This quest is going to lead to a nice collection of MCU modules.

Lucky you! It's on my list to get.

You should give mbed BLE library a try using mbed Studio, or it could also work via Arduino IDE (not confirmed but should in theory). This library, based on the Cordio BLE stack, works very well. I've been working through it. If it's of interest I was planning to create a blog about what I've done. I used my old Particle Xenon feather board (nRF52840) to develop an app.
