Hi,
I want use 20706 to connect one master and more slavers.
And when I connected the third peripheral, directly return the connection down error. The disconn reason is 0x04.
I tried a variety of connection parameters ,but all of them didn't work.
Solved! Go to Solution.

What application are you using? Could you try the following demo: CYW20706 – BLE Secure Data Hub
Also you may refer to this thread about the maxmium link number.

So you mean the BT connection, not BLE? It can act as master for a max of 4 different slaves if the device act as slave at the same time. The number will also limited by the resource usage of the application.
Why do you need 19 simultaneous connection at the same time for audio application?

Sorry, not BT, is BLE of the headset demo.
in the src "hci_control_le.c", row 49, there is "#define LE_CONTROL_MAX_CONNECTIONS 20"
Isn't the macro definition here that there are 20 max connections?
