Not able to Close the Gatt connection for rescan

[gapandr1479]

Hi,

I am using Blufi library in my project, i am able to connect and working the flow. But if any disconnection happend like user click on back in between the connection or any Esp device error, we are not able to re-scan the device. Because current connection is not closing. I am closing as blufiClient.close() - is not working. for that I need to close the app and remove from background. Then only new Device is coming to searchable.

can any one help me how to close GATT properly... i tried disconnect() and close() also but still not working..

@gapandr1479 I am late for this however, still if it helps.

Espressif have provided separate requestCloseConnection() and close() methods. Then destroy the current Activity.

this is my code in onDestroy()

if (blufiClient != null) {
blufiClient!!.setBlufiCallback(null)
blufiClient!!.setGattCallback(null)
blufiClient!!.requestCloseConnection()
}

but still connection not closing, i did not find the call() in the library. can you please provide more info, how to close the current connection.

where iOS just closing by blufiClient.close() is working but Android still connection a live untill app forcefully close.

Typo.

Yes it is the close().

EspBlufiForAndroid/app/src/main/java/com/espressif/espblufi/ui/BlufiActivity.java

Line 506 in b531b20

disconnectGatt();

I used requestCloseConnection(), close() and then finish() method.
On connecting again, you can check existing connection, if it exists, disconnect it and then create new instances.

Also first you can try closing the connections and then setting them to null. What do the logs say?
