Portenta H7 UDP Multicast not working - mbed v2.4.1 #321
Comments
Hi @Zuroy, |
I'm trying to use the MDNS_generic Library which uses UDP Multicast. The code il correctly compiled but it does not work. |
AFAIU |
Nope. since I'm using the ethernet connection. Do you have any suggestion? |
### Releases v1.3.0-beta1 1. Add support to Portenta_H7, using WiFi or Ethernet. **Still not working**, just for preliminary tests. Check 1.1 [**Portenta H7 UDP Multicast not working - mbed v2.4.1** #321](arduino/ArduinoCore-mbed#321) 1.2 [**Portenta H7 MDNS Library compatibility** #4](#4) for latest situation.

You can test by using the latest MDNS_Generic releases v1.3.0-beta1 for Portenta_H7, either Ethernet or WiFi. Thanks for looking at this issue, Best Regards, |
Already try with The Patches are copied / modified from this core's PR WiFi UDP & Multicast Functionality #14 |
Do you have any news? I'm trying to rewrite the C code but I'm stuck on the phy configuration. |
We allocated some time to look for a fix in our backlog, hope it will be fixed by the next core release 🙂 |
Thank you very much! |
@Zuroy @khoih-prog I pushed #337 , tested it with Portenta, ArduinoMDNS and WiFi and it works fine 🎉

Hi @facchinm , @Zuroy , @pennam , @manchoz I've just tested and confirmed the PR SocketWrapper: UDP: send packet on endPacket(), not on write() #337 fixes the UDP Multicast issue. Many thanks for the beautiful fix BR, Test Results
1.1 Terminal output
1.2 Ping using mDNS hostname => OK
2.1 Terminal output
2.2 Ping using mDNS hostname => OK

Check [SocketWrapper: UDP: send packet on endPacket(), not on write() #337](arduino/ArduinoCore-mbed#337) and [Portenta H7 UDP Multicast not working - mbed v2.4.1 #321](arduino/ArduinoCore-mbed#321). To be used temporarily until the PR included into new core
UDP Multicast is still not working in this version.
