STM32WB as dual roles: master/slave at the same time

[Haizhou Li]

Hello,

Can I use STM32WB as master/slave at the same time? Our project requests the product to talk with cell phone and other accessories at the same time.

If so, is there an example I can refer to?

Thank you very much!

​You should have a look at the BLE_p2pRouter project here: STM32Cube_FW_WB_V1.8.0\Projects\P-NUCLEO-WB55.Nucleo\Applications\BLE\BLE_p2pRouteur.

In this use case, the STM32WB devive maintains seven simultaneously connections to transfer information from one device to an another remote.

A smartphone application is connected to the STM32WB55 P2P router device allowing the control of six others peripheral STM32WB devices.
