Adapting Arduino-AppleMidi-Library to wifi for ESP8266 #11

Closed rubenbroman closed 9 years ago

rubenbroman commented 9 years ago

Hi,

I'm trying to adapt this lovely library to be used on the ESP8266 using wifi. So far I've changed all the EthernetUDP calls to WiFiUdp. It seemed to be working fine and when I connect to the ESP8266 from the OS X Audio Midi it seems like I get a connection. I won't get anything in the Midi monitor app and the ESP8266 starts spitting out gibberish over serial.

Do you have any idea where to start looking? I'm not really a programmer and I don't know much about the inner workings of AppleMidi so it would mean a lot to get some help.

This is what the serial output looks like. The example code follows.

OK, now make sure you an rtpMIDI session that is Enabled

I just read some of the closed issues and realised that the problem might be that I'm using IDE 1.6.5 and not IDE 1.0.*. Could that be it? I'm on OS X Yosemite by the way.

I'll do some poking around with Wireshark tomorrow and I'll post any findings.

lathoub commented 9 years ago

Hi, I recently tested the lib with 1.6.5 - so you should be fine. Just reading through the log, it might be input buffer size related. I have no ESP8266 (maybe i should get one :-)) to test. Please post your wireshark results, alternatively, you can compile using verbose debugging switch on (see APPLEMIDI_DEBUG_VERBOSE in setting header file)

rubenbroman commented 9 years ago

Thanks for your quick answer.

I really think you should get a ESP8266, they're dirt cheap and there's plenty of things you can do with them.

I switched on the verbose debugging and it looks like the protocolBuffer contains the bytes that are sent but that they're not correct RTP data, given that it's the "unsupported version 3". I uncommented the return 0; in the version check so that you have some more info if that helps.

I'm really grateful that you've made this library and that you're supporting it. It would be great if we could get it working on the ESP8266 (hoping that the latency will be good enough). Thanks!

Here's first the Serial output and underneath is the Wireshark data.

Hi, I am working on a similar project using this good library with ESP8266. Had the same problem.

in WiFiUdp.h we have #define UDP_TX_PACKET_MAX_SIZE 8192 in EthernetUdp.h we have #define UDP_TX_PACKET_MAX_SIZE 24

Changing the UDP_TX_PACKET_MAX_SIZE to 24 in WiFiUdp.h fixes the problem with receiving midi. No gibberish anymore.

But I still cannot send midi out. Messages get all the way to: internalSend(Session_t* session, MidiType inType, DataByte inData1, DataByte inData2, Channel inChannel)

But nothing is received on a computer. I would appreciate any help.

lathoub commented 9 years ago

I have a ESP8266 now, but now I need a 3.3V Serial-USB programmer...

Good that got the buffer size figured out (I had a hunch it was that).

On Windows, I have rtpMIDI open so I can see the latency timer changing (sign that connection is alive); I also have a MIDI-OX session running, logging both MIDI in and out, and Wireshark, logging all rtpMIDI related traffic.

Do i get it right that you don't see any outgoing bytes on Wireshark?

lenkost commented 9 years ago

For some reason WiFiUDP does not remember the last RemoteIP and Port. If I set it up manually, the sample sketch works OK. This is temporay, for testing only:

void beginWrite(WiFiUDP* udp)
{
    byte remIP[] = {0xc0, 0xa8, 0x0, 0x3};
    uint16_t remPort = 5005;
    udp->beginPacket(remIP, remPort);

// udp->beginPacket(udp->remoteIP(), udp->remotePort()); udp->write(&ddddd, sizeof(ddddd));

lathoub commented 9 years ago

Good news! Once I have a 3.3V programmer I will try to get it working, based on the above comments (albeit I have to say that WIFI is not ideal to send MIDI notes - when testing on a portable computer I do notice that notes come in 'bursts' with a little delay. I do not exactly know your use case, but keep the latency in mind

I will try to pass the UDP class as a template argument, that has least impact and max flexibility (I think)

lenkost commented 9 years ago

I finished my project and it works great. There is no latency at all when using with PC. Thank you for your great library. One issue remains. I understand that sysEx part is not finished yet. Is it possible to have it in simplified way? Just to get an array of bytes between F0 and F7 and number of bytes without any parsing of the content? For OnReceiveSystemExclusive event? And the same for sending? Thank you again.

rubenbroman commented 9 years ago

Wow! I'm really happy to see that you've got it working. I haven't had time to do any testing but did a quick search to see if anyone else has had problems with remote ip on up and found this: https://communities.intel.com/message/240509

Is that maybe applicable for us?

Cheers

lenkost commented 9 years ago

I understand that Remote IP is the IP of the last received packet. I save it in a session structure during sync and then use it to send packets back.

As I said it works perfect with Windows but I could not make it work with Mac or iPad. Any ideas?

lathoub commented 9 years ago

Good to hear it works! Very nice.

I'm considering adding templates to AppleMIDI, so that you can pass the WiFiUDP as a template argument. This way I can support multiple UDP classes (assuming they use the same methods). Would this help you? Also, what structure did you modify? I could add a void* userData attribute to the struct to support this.

lathoub commented 9 years ago

Added template support for the AppleMIDI library. This should make adding other ethernet libraries easier (?). Can you have a look? See the 3 examples on how to use. As I don't have a 3.3V programmer I can't test it with the Esp8266

I will close this issue, please open a new issue when you encounter problems
