Question

connect BLE to several smartphones

Is it possible to get connection with several smartphones on the STM32WB?

As I understand the STM32WB can connect several servers but not clients (smartphones), or I got it all wrong?

Thanks,

Lior Malik

​There is no restriction at GATT level (Client/Server architecture).

The STM32WB can support up to 8 connections but only 2 slaves at Link layer level (GAP level).

​Please have a look the STM32Cube_FW_WB_V1.4.0\STM32Cube_FW_WB_V1.4.0\Projects\P-NUCLEO-WB55.Nucleo\Applications\BLE\BLE_p2pRouteur project.

Go to the readme.txt file

demonstrate STM32WB55xx capabilities:

-- 1 slave & 6 masters connections on same device

-- GATT Server & GATT Client on same device

-- Automatic reconnection

-- Special Advertising format is proposed

-- Proprietary Services & Characteristics are used
