On board Bluetooth (Classic not BLE)

[wbadry]

Hi,
Is there any example for using the onboard BT as a classic, not BLE? It is mentioned in several places that it supports both classic and BLE but couldn't reach any example. Thanks

I think all I have ever done is BLE not classic bluetooth. Not really sure what the difference between them is. Several chips seem to be able to do both and I think the portenta can.

Looks like BC can send more data but only very close, BLE sends less data but farther. That's my limit. https://www.thedroidsonroids.com/blog/bluetooth-classic-vs-bluetooth-low-energy-ble Arduino must have some BC examples.

Thanks, @hpssjellis . Actually, the classic bluetooth is always used externally via additional hardware like HC-05. I was unable to find a generic library for classic Bluetooth and Arduino as it is impossible to know how every chip work if it is non-standard.
