Hi @M623​ ,

What do you mean by "a classic bluetooth device" ???

Anyways the response is YES.

Please refer to the STM32CubeWB FW package under directory : Applications/BLE

There are lots of BLE projects and you can find some that use a Smarthone.

Best Regards,

Ons.

Yes you can connect to a classic Bluetooth device. The BLE standard (starting from Bluetooth 4.0) is just an extension of the classic Bluetooth standard with a key focus on low power consumption.

Thank you for your answers.

@Ons KOOLI​ : About classic bluetooth you can see in the Official website of bluetooth : https://www.bluetooth.com/learn-about-bluetooth/radio-versions/

I read that BLE is independent of classic bluetooth and has no compatibility so i'm a little confused : https://en.wikipedia.org/wiki/Bluetooth_Low_Energy

In STM32CubeWB FW package i can find the exemple between 2 BLE devices but in can't find an exemple between a BLE device and a classic bluetooth device. Do you have some project exemples ?

Thank you.

In fact BLE devices can connect to smart bluetooth devices but not to classic bluetooth devices. See presentation in attachement.

@Remi QUINTIN​ is there any ST product supportingBluetooth Classic?

(i couldnt find any)

Or any ST preferred third party solution?

Ive been looking at TI solutions (CC2541), or even the ESP32 but i would preffer to stick with ST
