Disconnection request from peripheral device.

[viswa]

Hi Everyone,

sdk : nrf Connect v1.7.0

ide : VS code

I was trying out central_hr sample on nrf52840 dk. I have simulated hrs server in nrf Connect mobile application. So basically our dk is Central and nrf Connect app is peripheral here.

Suppose I have disconnected in nrf Connect app,after central made a connection, I couldn't see any callback related to disconnection on central side.

This isn't the case with peripheral_hr sample in nrf52dk. 

My question is ...

1.How the Central device knows if the peripheral is still in connection?

2.Can we disconnect from peripheral side in a ble connection?

3.Suppose I have both functionalities central and peripheral running parallely in a nrf52 chip, how to handle connection and disconnection from two independent roles?

Hi

I'm sorry, can you upload a screenshot of the log from your nRFConnect app? "Connection terminated by peer" still points to a disconnect occurring, which is expected. It's just different how the logging is done in the nRFConnect app and your other peripheral.

Best regards,

Simon

Hi Simon, though I have disconnected from nrf Connect mobile App, it's still sending some notification in background. That's the reason I couldn't get a disconnect callback.

How to disconnect properly from the app?
