I have a seemingly simple project to start learning App Inventor but I have run into a snag I can't get around. Basically I want to connect from my Adafruit Feather Bluefruit M0 LE board to my android phone or my iPad Pro. The Feather is measuring the output of a sensor connected to Pin #A0. I am trying to at least see the output of that pin but eventually the calculated values from that Pin and then plot the data. I can get the project App Inventor + IoT: Basic Bluetooth Connection Setup to run where it scans and then connects to my feather (so it says) but I can't get further than that to read data. It seems all the examples I find on the web use BluetoothClient instructions whereas this example uses the BlutoothLE1 extension and therefore BluetoothLE1 instructions. So this is all I've got:
Can you point me in the correct direction? The BluetoothLE1 uses Service and Characteristics UUID but I don't understand them nor can I find descriptions of their use. Can you suggest an example that I can work from?
Thank you
Doug
