Hi.
My T3.6 with WIZ820io using the adaptor plate works perfectly on DHCP and static ip. I want to add Bonjour support and installed this library (https://github.com/TrippyLighting/EthernetBonjour) which installs and compiles successfully.
it reads the MAC address correctly and also I can ping the DHCP-assigned IP. As soon as the code uses Bonjour things get mixed up.
EthernetBonjour.begin("arduino");
is ok - however I can't resolve arduino.local on my mac.
2nd line:
int res = EthernetBonjour.addServiceRecord("test._http",
80,
MDNSServiceTCP, NULL);
works sometimes. after unplugging the Teensy it always continues and res = 1 which means success. Sometimes it hangs/crashes inside this method. When I use:
int res = EthernetBonjour.addServiceRecord("test._http",
80,
MDNSServiceTCP);
without the TXT record, it crashes way more often.
The NULL thing is something I came up with by looking at the library code:
No matter what I do, when having a good spin (no crashes) the loop() get's executed I can see the webserver page using the ip address but the Teensy will never register it's hostname nor any Bonjour service records (using OSX Bonjour Browser application I can see a lot of Bonjour services of other devices in my LAN but never my arduino).
In addition none of the example sketches bundled with the library works correctly. My network seems to be OK, I tried different routers - no luck.
I tried for hours but couldn't narrow it down so far. I would like to ask:
- my WIZ820 works basically. But multicast doesn't seem to work. Is this a known limitation?
- is this library (which I think it's the newest I've found and is built on EthernetUDP rather than direct HW calls to w5100) compatible with the T3.6? Which library is a good one to test?
- are there any differences between a Teensy 3.0 to Teensy 3.6 in regards to this? Could it be that this library simply won't work on a 3.6 but would work fine on 3.0/3.1/3.2?
- Are there any plans to include Bonjour in the Teensy library of Ethernet?
- any pointer on how to troubleshoot this?
any help would be very much appreciated! thanks!!!!

// service type, like _mycoolservice - As long as your clients know what to
// look for, you're good to go.
// The second argument is the port on which the service is running. This is
// port 80 here, the standard HTTP port.
// The last argument is the protocol type of the service, either TCP or UDP.
// Of course, our service is a TCP service.
