quiet
Swift sample app
Hello @brian-armstrong ,
I was creating a sample Swift app. https://github.com/winster/QuietShare
Getting an error while setting the ReceiveCallback. I could not find the definition of that. Can you please help?
Regards Winster
Hello Brian Armstrong, how are you? Hope everything's ok. I have been looking at winster quiet share implementation code on swift and compared with you OBJC code. There is something strange happening: 1- I can transmit quiet without any problem to any device:
@IBAction func transmit(_ sender: Any) { let frame_str = "winster@quiet"; let data = frame_str.data(using: .utf8); self.tx.send(data);
But when I try to receive it, it works on the simulator but never worked on the mobile phone itself: The permission was granted in info.plist and manually on the mobile.
AVAudioSession.sharedInstance().requestRecordPermission({(granted: Bool)-> Void in
if granted {
if self.rx == nil {
let rxConf: QMReceiverConfig = QMReceiverConfig(key:"ultrasonic-experimental");
self.rx = QMFrameReceiver(config: rxConf);
self.rx?.setReceiveCallback(self.receiveCallback);
}
} else {
print("Permission to record not granted")
}
})
Can you help me? Thank you very much.
My reiceiveCallback function is this:
func receiveCallback(frame: Data?) { let msg = String(data: frame ?? Data(), encoding: String.Encoding.utf8) ?? "data could not be decoded"; print(msg) }
Debugging the code... it seems that the problem resides on this func: receiveCallback
@carlosguedes Are you getting an error? Is the receiver just never receiving anything?
Hello Brian, no, no error messages at all. The receiver just never received anything. (On the device). I also granted the right to use the Microphone on the application. Thanks

What model of phone is it? How is its mic oriented with respect to the speaker, and how far away?
Brian, I tryed in a lot of positioning, near by, a little far, 50% volume, 100% volume. The device is an Iphone 6s Plus, but i also have tryed on a iphone 6. Ios 10 and 11 didn’t work. Its strange is that on the simulator it works, but it doesnt on both devices. Even with microphone permission granted it simply can’t receive. (For sending is perfect). Maybe im missing something in the code I sent you... I never could get the receiver working.

I will provide the source and a little sample of the error to you tomorrow as i am out of the office
Thank you for attention

It's hard to guess what's going on, Quiet's debugging tools aren't as good on iOS as elsewhere unfortunately. I haven't had a chance to test on newer iOS versions but I can't think of a reason it'd break there.
I'm not sure how feasible it is for you to check this, but if you're comfortable with the code, it would be interesting to check the QMFrameReceiver. Specifically, to get some printfs to show whether the quiet_frame_receiver_callback is being called, and if it is, whether any of the samples (d->monoBuffer and casted_buffer) are nonzero. Knowing that much would at least hint strongly at the sort of error it could be.
Hello Brian thanks for all attention. I really can't make the receiver works on the Iphone, but inside the simulator, everything goes alright. And the simulator, emulates iOS 11. The quit frame receiver callback is indeed called on the emulator but inside the mobile phone seems that the function is never called.
@IBAction func scan(_ sender: Any) { if AVAudioSession.sharedInstance().recordPermission() == .denied { self.testing.text = "Deu pau" }
AVAudioSession.sharedInstance().requestRecordPermission({(granted: Bool)-> Void in
if granted {
if self.rx == nil {
let rxConf: QMReceiverConfig = QMReceiverConfig(key:"audible");
self.rx = QMFrameReceiver(config: rxConf);
self.rx?.setReceiveCallback(self.receiveCallback);
}
} else {
print("Permission to record not granted")
}
})
} No exception is on the debug.
func receiveCallback(frame: Data?) { let msg = String(data: frame ?? Data(), encoding: String.Encoding.utf8) ?? "data could not be decoded"; self.testing.text = "TEST" print(msg) self.testing.text = msg
}
}
*Test is a label I put on the code...
The most bizarre thing is that it works on the simulator, but not on the device. That's impressive. All device volumes are ok, everything's ok. There is only one situation that I receive on debug. When I hit the scan button first, it send me this message:
2018-01-11 09:43:18.445555-0200 QuietShare[7028:386670] 317: ca_debug_string: inPropertyData == NULL
But nothing more...
That's all the log I could find in de the device... At my view... nothing abnormal:

Unfortunately that doesn't tell me much. If you get a chance to try what I mentioned (inserting some printfs into QuietModemKit's quiet_frame_receiver_callback) that would definitely help. Otherwise I will see if I can get some time to debug myself this weekend or next
I see, and I appreciate for your attention. I will try to bring more information to you. Thank you very much

Hello Brian! Thanks for all the help! I tested your new version for the issue but I'm still facing the same problem. I think I could find the exact log when trying to record (receive the message). Hope it can help you:

Maybe I can help you providing my src. Hope can't make it clear for you. Thank you for everything. QuietShare-master-2.zip
@carlosguedes I had a look at your zip, and it seems the new code I added is not present here (QuietShare-master-2/Carthage/Checkouts/QuietModemKit/QuietModemKit/QMFrameReceiver.m is still the old version). I tried running carthage update from QuietShare-master-2 and confirmed it did update to the new version, so please run that and try again.
Ohh, Im so sorry. Maybe I made some mistake. I had even copied by hand the new code inside the qmframereceiver.m and possibly made some mistake. So sorry. I will try again. Thanks

@carlosguedes No worries, maybe it was just the .zip that didn't have the new code? Let me know if you have any more questions about it.
Brian! How are you?? Thank you very much!!! IT WORKED as a charm!!! I think that the example I created with send / receive don't work very well... it seems that maybe because some lack of threading it can't send and receive at the same time... when I got to quiet-js example, it worked perfectly. So... I think the problem is now solved... wow! You are great! Is there anything I can do to support your project? Thanks

@carlosguedes Awesome, glad that got it, and sorry it was broken for you for a while. Now go make something awesome, and tell people about it :)
Also regarding send and receiving at the same time, that should be fine. I'd be interested in seeing the code that wasn't working for that.
@carlosguedes I have facing same problem, receiveCallback method not called, what I have to do for fixing this issue.
@brian-armstrong @winster @carlosguedes Hello. Thanks for your nice hints on this chat.
I just cloned winster's repository and tried to test app. I am able to hear some sounds when I click "transmit", but receivercallback never called.
I also tried Carlos 's "master-2.zip" which was discussed on above chat, but same issue.
May you explain a bit more? Please help me. Thanks.
For anyone who faced the same issue as @carlosguedes, I believe the problem was caused by the device dismissing the recording session when accessing the speakers.
Anyway, with swift 5, iphone6s, and iOS 13.1 I was able to solve it by adding
try? AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playAndRecord, mode: AVAudioSession.Mode.videoRecording, options: AVAudioSession.CategoryOptions.mixWithOthers)
to my app on startup
Cheers
@NAolERr Would you be kind to show me your source code for receiving ultrasonic frequency? I could not get it working in my Swift 5 project (Swift UI)
@brian-armstrong or if you have any idea?
Happy to help contribute once I get this working
Thanks! Brandon
Hi @brandex007
I will send you whatever I have together, It is a bit of a mess as I have put this aside for now. some pointers: send date now button sends the data through sound. the rotating wheel starts the continuous microphone access. (it cannot be turned off) use two phones to test it out. the green light is only used to detect if the phone heard itself and the delay
if you feel you have the knowhow to do, there was one thing I was trying to figure out. I'm trying to save the sound that is being played so that I can use it again without processing it through the library. maybe save it in a local variable as data and play it again.
