Hi Hung,

I adapted the multirole LESC example to run on our HW (as I do not have a PCA10040 yet and our HW does not have buttons and leds) and the behavior was the same. During further investigation I had a look on the dongle I am using for the PC. It was an older PCA10031. After I replaced it with a PCA10059 dongle, the behavior is as expected (security mode 1 level 4 on each reconnect).

Thanks for your help, this issue is solved.

Hi Florian,

It looked quite strange to me. Could you please try testing again using our example \examples\ble_central_and_peripheral\experimental\ble_app_multirole_lesc\

The example use LESC and numeric comparison.
This is what I got when testing with the example, they are all mode 1 level 4 when re-connected:

If it only happened in your application, please send a minimum version of the application that can re-produce the issue.
