I'd use a Arduino micro + bluetooth board like HM10 board. Or use the device you have pointed before. It's up to you. They have the same use. Remember that pairing BT is not a simple task depending on micro's role(master or slave).
May I ask the question - Why don't you use an ESP32 with BT ? - That way you have both Bluetooth and WiFi - so your device will receive (at close proximity) from Bluetooth (if you so desire) and at long distance with Wifi (internet connection etc as a given then)
and possibly, if you want to look at IoT in the future, this board could also work for you: https://www.elecrow.com/esp8266-iot-board-p-1591.html - it does not have bluetooth - but this can be added as a supplemental board with a bit of effort.
Hello, thank you, that helps a lot. And IoT is also very interesting for me. I will order a board and try to install the addons for ESP32 in the Arduion IDE as first step. I am sure I am comming back with some questions ;-)
best regards

Esp32 is an amazing piece of hardware. At the price of a cinema ticket has an impressing mix of functions. If you don't have the need for a lot of GPIO it's something to think about.
