RxAndroidBle Scan Timeout

Question

I need help. How to set scan timeout for example 10 seconds when i am using rxandroidble.

            scanDisposable = rxBleClient.scanBleDevices(
                new ScanSettings.Builder()
                        .setScanMode(ScanSettings.SCAN_MODE_LOW_LATENCY)
                        .setCallbackType(ScanSettings.CALLBACK_TYPE_ALL_MATCHES)
                        .build(),
                new ScanFilter.Builder()
                        .setDeviceAddress("B4:99:4C:34:DC:8B")
                        // add custom filters if needed
                        .build()
            )
                .observeOn(AndroidSchedulers.mainThread())
                .doFinally(this::dispose)
                .subscribe(
                    resultsAdapter::addScanResult, 
                    this::onScanFailure
                );

If you want to emit an error (TimeoutException) when there is no emission for a specific time then you put a .timeout(int, TimeUnit) after the RxBleClient.scanBleDevices().

If you want to simply complete the scan without any error then you put .take(int, TimeUnit) in the same place as above.

this will work when device is not found. But if we want to set timeout even if the device is found then how do we set that? i.e. `SCANNING PERIOD` – Hunt Jan 22 '21 at 10:13
`.take(int, TimeUnit)` – Dariusz Seweryn Jan 22 '21 at 11:21
