Does anybody got an app inventor2 "project" to communicate with the (Adafruit) Bluefruit LE UART (or SPI) ? Note: my Android version is 4.4.2 (LE "advertising" not supported) I've tried: a Bluetooth standard method (usually used for Arduino...) based on BluetoothClient (AddresseAndNames), listPicker(selection)... however not working => get stuck in the "listPicker.afterpick". with the BluetoothLE extension for app Inventor2 (here I discovered that I got a too old Android OS, + cell phone do not allow to easy upgrade to Android 5. NOTE: work fine with Nordic nRF UART 2.0 and Adafruit Bluefruit app THX
