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)

May I share some resources with you ?

B4R Library and Example here: https://www.b4x.com/android/forum/threads/resp32bluetooth-esp32-classic-bluetooth.93257/#content
and here: https://www.b4x.com/android/forum/threads/resp32simpleble-esp32-ble.93287/

ESP32 Board: https://www.banggood.com/ESP32-Deve...-p-1109512.html?rmmds=search&cur_warehouse=CN
and here: https://www.banggood.com/Wemos-ESP3...s=detail-left-hotproducts__1&cur_warehouse=CN

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.

and if you really want to go over the top with NB-IoT etc then look here: https://www.dfrobot.com/product-1732.html
and tutorial here: https://www.dfrobot.com/wiki/index....NB-IoT/LTE/GPRS_Expansion_Shield_SKU:_DFR0505

AND the good thing is that the code shown there can be ADAPTED to B4R !!


Enjoy !!

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
