Bluetooth/WiFi doesn't require embedded Linux. The venerable ESP8266 can be easily programmed through the Arduino IDE.



"Venerable" implies some worthiness.

ESP8266 is a hacker friendly wifi gadget, for $2, but otherwise garbage.

You get what you pay for.

Also it's wifi only, not bluetooth.


In what ways is the ESP garbage?


ESP32, the successor to the ESP8266, has both WiFi and Bluetooth, but it's fairly expensive.
