CC2540EMK-USB: How to filter Link Layer and L2CAP packets

Part Number: CC2540EMK-USB

Hello,

I am using TI BLE sniffer. How to filter Link Layer and L2CAP packets

When I keep PTY=Empty PDU, I am able to filter out Empty packets.

But not able to filter out PTY=Control for Link Layer packets.

Even with OPC=0x0C, not able to filter.

In below snapshot how to filter only LL packets.

  

Similarly how to filter out L2CAP packets.

Thanks & Regads
