ble_app_multirole_lesc is not working in SDK15.2

youssefchei

Hello 

I'm using SDK 15.2 on nRF52 DK to test the ble_app_multirole_lesc example.

I downloaded the code to nRF52 DK to act as central.

I commented the scan_start() function (main.c line 276) then I downloaded the code to the other nRF52 DK to act as peripheral 

I also added DEBUG in the global defines.

The problem is the secure connection has never established.

The logs below are the peripheral traces 

/**********************************/
