Robin, thank you for those links. I will start reading and watching them.
I can figure out how to take a reading on the mag or accelerometer.
Where I am having trouble is the BLE part of the equation. I just want to send a signal, do I have to do advertising and or GATT services, or can I just send a signal without all of the BLE ceremony?
