CYW20706 supervision timeout

[adam]

Hi, 

I am using CYW20706 as BLE peripheral, 

and using nRF connect App to connect 4 mobile phones as central, 

connect interval: 200ms, slave latency: 0, timeout 4800ms.

There did not do anything but only keep under connection.

Few hour later, there will happen disconnect and get the reason 0x08 supervision timeout.

After 2 devices disconnect with 0x08 and ohters 2 device still under connection.

I have read this https://community.infineon.com/t5/Studio-Bluetooth/Maximizing-number-of-connections-with-CYW20706/m-...

He seems to can stable connect 4 devices.

Is there any suggestion?

Hi @adam ,

Are you using any existing example project or any custom application?

Can you try with different connection intervals and see if it works?

Thanks and regards,

Hi @advait_kulkarni , 

I modify project base on hello_sensor, 

I have tried connection interval 200ms, 

but it still happen 0x08 supervision timeout.

Now I am testing connection interval 200ms and sleave latency 2, 

It seems connect more stable than before.
