Kw36 : Phone shows KW36 as connected after restarting the KW36

[skalyan2]

Hello,

Tried the following sequence in FRDM-KW36 ,

  -> Connect and pair a phone to KW36.

  -> Reset the KW36.

Expected Behaviour : 

    -> The previously connected phone should get disconnected from KW36 immediately.

Actual Behaviour : 

   -> The previously connected phone shows still shows KW36 as connected for 10-15seconds.

Regarding this issue, when i try to debug the issue by keeping break point in the event "gConnEvtDisconnected_c" during reset,the break point was not hit, my question is , is disconnect request is sent to phone when the reset happens? if sent why we are not receiving the "gConnEvtDisconnected_c"  or is there any other generic call back event that will come when we reset KW36 to show that the peerdevice is disconnected?

Hi Sai,

No, chip will not send disconnection request when it is reseted.

the disconnection time is depended on supervisionTimeout time which is negotited in connection event when master or salve device is losted.

Hello,

Have you tried using the temperature collector example? Also, could you please share the sniffer log of the communication? During those 10-15 seconds , does the device received the message ? Which phone and example are you using ? Did you modify something else?
