I would like to write the same command to several devices and receive notification from each of them. With my current code, I am able to do this but I can't tell the MAC address corresponding to the each notification since they are all sharing the same Characteristics UUID.
Here is my code:
for (Map.Entry<String, RxBleDevice> entry : rxBleDeviceHashMap.entrySet()) {
bleDevice = MyApplication.getRxBleClient(context).getBleDevice(entry.getKey()); // key is MAC
connectionObservable = prepareConnectionObservable();
connectionObservable
.flatMap(new Func1<RxBleConnection, Observable<Observable<byte[]>>>() {
@Override
public Observable<Observable<byte[]>> call(RxBleConnection connection) {
return connection.setupNotification(UUID.fromString(Constants.CHARACTERISTIC_UUID));
}
}, new Func2<RxBleConnection, Observable<byte[]>, Observable<byte[]>>() {
@Override
public Observable<byte[]> call(RxBleConnection connection, Observable<byte[]> apScanDataNotificationObservable) {
return Observable.combineLatest(
connection.writeCharacteristic(UUID.fromString(Constants.CHARACTERISTIC_UUID), command),
apScanDataNotificationObservable.first(),
new Func2<byte[], byte[], byte[]>() {
@Override
public byte[] call(byte[] writtenBytes, byte[] responseBytes) {
runOnUiThread(new Runnable() {
@Override
public void run() {
onWriteSuccess(writtenBytes);
}
});
Log.d(TAG, "responseBytes: " + ByteUtil.bytesToHex(responseBytes));
return responseBytes;
}
}
);
}
}
).flatMap(new Func1<Observable<byte[]>, Observable<byte[]>>() {
@Override
public Observable<byte[]> call(Observable<byte[]> observable) {
return observable;
}
})
.first()
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Action1<byte[]>() {
@Override
public void call(byte[] bytes) {
onNotificationReceived(bytes);
}
}, new Action1<Throwable>() {
@Override
public void call(Throwable throwable) {
onNotificationSetupFailure(throwable);
}
});
}
Getting the MAC address using bleDevice.getMacAddress() is not accurate because the response notification is much slower compared to the loop. I always get the last bleDevice in the loop.
Hope there is some way to pass the MAC address over.
Thank you.
