Send data WiPy to LoPy via BLE

[amartinez]

Hi everyone.

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?

Thank you!

Hi @amartinez,

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!

Thanks!
