In standard sdk 17.0.2 is it possible to know which devices did i accidently disconnect?(Interactive command s140)

for example

my central is the interactive command app

and the  

Peripheral 

has N  for example lots of light switch

and one of those light switches accidentally disconnected (maybe crashes or smth)

so how can I know which light switch is disconnected 

as in mac address

it only shows

<info> app: CENTRAL: Disconnected, handle: 0, reason: 0x8

without any mac address

Hi

Yes, if you have the connection handles of the connected devices, you can then find out which one was disconnected (by accident) by finding which one was missing. Our ble_app_multilink_central example project in the SDK has an example of how this can be done. See the BLE_GAP_EVT_DISCONNECTED event in that example for details. You can also check out this case where this has been discussed before.

Best regards,
