Hi,all

As said above, i've tested two laptops, and this situation happened. I have no idea why this will happen. Is there may  any problem with the connection parameters in the code?

(I use SD s132, V6.0, SDK15.0)

I can't find anything in specific wrong here. It seems simply that the laptop disconnect, without any error code:

Have you tried some of the other examples in the nRF5 SDK to see if the same occurs?
