nRF51 interval and scan window

Question

Hi, 
 How can I know the value of the interval and scan window for an nRF51 dongle? Is there any way to change these values? W hat is the valid range for both parameters ? 
 I'm using BLE beacons iBKS105 (based on the nrf51822 chipset from Nordic Semiconductor) and Wireshark 2.4.6 
 Thanks in advance!

Hello, 
 The sniffer firmware does not use the SoftDevice, so it works a little different than when you program it. It does not use a scan interval and window like in the link that you posted. When you have selected a specific device, it will follow that device between the channel hops. 
 
 But are you sure that you see more packets when you use the v2 of the sniffer than you see on v1? I have not managed to replicate this, but the only thing I can think of is that this is due to the fact that you have several beacons in the same application. Are both of the beacons on the same nRF? Would it be possible to share the application, so that I can reproduce the sniffer issue here? 
 
 Best regards,
