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
But CYW20706A2 don't send it and LE data packet for connection.
so device is disconnected. why don't send LL_PHY_RSP on CYW20706A2??

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
