BLE and LLD at the same time

[PCu1]

Hello,

Is it possible to work with one STM32WB central role as router in BLE and in LLD mode?

As router I mean communicate in BLE to one smartphone and communicate in LLD with several remotes.

The issue is that the CM0 coprocessor firmware is different for BLE and LLD. 

In my opinion it is not possible.

Hello,

Unfortunately, it's not possible to use the STM32WB in BLE and in BLE LLD mode at the same time.

Thank for your answer.

I found (by reading some BLE doc) that I can communicate in P2P in advertising only and send my data from the remote(one byte) in the advertising payload, without handshake.

And in the same time the smartphone can connect with the router.

I did some tests and it works.
