Send data WiPy to LoPy via BLE
It's the first time I'm working with BLE and it is a bit confusing for me to understand the documentation.
I just want to send data (a string variable) via BLE from a WiPy to a LoPy.
I understand how to create the connection, but I don't understand how to send data.
The LoPy (receiver) is the Client and the WiPy (transmitter) is the Server? And so, the data is the Service?
Can anybody help me a bit with this?
There's a really good explanation about GATT (Generic Attribute Profile) here - https://learn.adafruit.com/introduction-to-bluetooth-low-energy/gatt
Currently BLE is the protocol available but classic Bluetooth will be coming in the future!
