I have a few of questions about Bluetooth:
- When an iphone is communicating with an apple watch using Bluetooth Low Energy (BLE), which device is the host? So, which device is the central and which is the peripheral? It is my understanding that an Apple Watch now acts as its own CBCentralManager for communicating with BLE peripherals.
2.Can an iphone emit a BLE signal and register on a scanner as a BLE device? Or does it always register as the central device?
3.Does an Android phone always register as the central device (this is what I’ve read so far)?
Thanks so much in advance for any information.
