STM32 Bluetooth Classic MCU

Hi, I am wondering if you can get STM32 MCU with integrated Bluetooth Classic as the only examples I have found (Like WB55) are all bluetooth low energy?

Hello @Linkpad 

ST is integrating the last BLE Technologie in the STM32WB series and specially in the STM32WBA series which include High data rate, long range, High output power and a Low-power messaging capability. I think that you can run almost all possible BLE applications using one of our MCUs. you can give as your project specification, and we may can guide you to a product that can do the job.

Best Regards.

Sorry to wake an old thread, but this has come up a few times recently:

But not if your application needs to do Bluetooth Classic !

At the time of writing, with very few exceptions, that means pretty much anything with BT audio:

Another example would be the Classic Bluetooth Serial Port Profile (SPP):

(There is no standard "serial port" profile for BLE - but plenty of proprietary implementations)

A complex system that works is invariably found to have evolved from a simple system that worked.A complex system designed from scratch never works and cannot be patched up to make it work.

I can confirm this. Thank you so much for this feedback @Andrew Neil . I've already mentioned that it implements BLE technologie.

Best Regards.
