FRDM KW36(BLE): Getting gHciRemoteUserTerminatedConnection_c as disconnection reason for every disconnection

Hi,

Whenever KW36 (BLE module) disconnects from the connected phone, the reason for disconnection in "gConnEvtDisconnected_c"is always gHciRemoteUserTerminatedConnection_c, But what I would like to know why NXP LE stack is not sending the reason "gHciPinOrKeyMissing_c" or any other disconnect reasons appropriately.?

Regards,

If you pull the device away, you will get the reason ‘gHciConnectionTimeout_c’ after disconnecting.

Hi Xing Chang,

Is there any disconnect reason for link key miss?

Hi pvelayu1@visteon.com‌,

When the KW36 loses the link key, the encryption will fail when reconnecting, but the kw36 will not be disconnected. The disconnection is initiated by the mobile phone.

Hello,

Do you have a sniffer log with the information you are mentioning ? How are you seeing this ? Also, which example are you using ? How are you configuring ? Are you using some mobile application ?

Hello estephania_martinez‌,

I am keeping breakpoint in the application event ""gConnEvtDisconnected_c"  during various disconnection scenarios but even at different disconnect scenarios, i could see always the reason as gHciRemoteUserTerminatedConnection_c.

I am using hid_device project, i am not configuring anything related to disconnect reason.

No i am not using any mobile application.

Hello,

Could you please share with me the sniffer log of the communication ? Also, have you tried using the temperature collector example ?

Hi Estephania,

I have attached the airtrace of the issue, where for every disconnection, gHciRemoteUserTerminatedConnection_c reason is received.
