After connection between my laptop and NRF52832 module for a while , "disconnected" happened. Why would this happen?

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)

An on-air sniffer log would be very useful:

Hi,

does it mean i need a hardware like dongle? but i just seem to see  NRF52840 dongle, if nrf5840  dongle can apply to my nrf52832 chip?

[Kenneth]

You will need one of these development kits or dongles to use the nRF Sniffer for Bluetooth LE:

• nRF52840 Dongle
• nRF52840 DK
• nRF52 DK
• nRF51 DK
• nRF51 Dongle

Run the sniffer when it fails, upload the log here, then we can analyze.
