From the log you posted it looks like your sniffer.cfg file is corrupted.

You can see that the file is located in the folder

C:\Users\dell\AppData\Roaming\Nordic Semiconductor\Sniffer\logs

Try to open the file and change the content to

comport = COM15

I also see that you are using Wireshark version 1.12.5, I recommend using version v1.10.x which is listed as the supported version in the nRF Sniffer User Guide v1.4

i change log.txt to [sniffer] comport = COM15 ,it can not work;the note is same as before.

You need to change the file called sniffer.cfg, not the log.txt file

Regarding the sniffer missing packets, see this post and comments.

my sniffer is still not recevice data,pls see "still loss data.pcapng"or"Loss data 2.pcapng",it can receive data when the phone disconnect device and wait 10 secs.

I see that you are missing alot of packets in the "Loss data 2.pcapng", but the "still Loss data.pcapng" looks fine(sniffer captures all the packets) until the master disconnects after 7 seconds. Are you doing something different between these two sniffer traces was captured?

Sigurd ( 2017-04-24 11:38:11 +0100 )editconvert to answer

no,is is same operate.Same device and sniffer tools,it ofter stop by CONNECTT_REQ or "Loss data 2.pcapng"situation.

Looks like the master is sending some L2CAP connection oriented channel packets. This is not supported by the regular SoftDevices. It also looks like there are 2 different master that tried to connect to the slave.
