Hi 

 

I am use CYW20706A2. and I want to connect special central device(BLE)

special central device prefer use LE 2M. 

so it send LL_PHY_REQ after device connected. But CYW20706A2 don't send LL_PHY_RSP

(my SDK is wiced studio6.4 and modus2.2(BTSDK2.8))

According to "BT Core Doccument",  if device receive LL_PDU_REQ, device have to send LL_PDU_RSP

Hi Sheetalj

I know that cyw20706 don't support LE 2M PHY.

But 20706 have to send PHY_RSP. But My Airlog don't capture it

and cyw20706 don't send LL_data for connected(Empty).

I think two device disconnected from supervision time. 

Thank you
