Re: [lwip-users] setting up multiple UDP connections with same prio and different data to send

If your network blocks broadcast you may use: If your NAT is 192.168.0.x You can broadcast you subnet with 192.168.0.255 or 192.168.255.255 etc... depends on Network definitions. -Original Message- From: lwip-users [mailto:lwip-users-bounces+noam=silrd@nongnu.org] On Behalf Of

Re: [lwip-users] setting up multiple UDP connections with same prio and different data to send

Why do you need IGMP ? Just set send to address to 255.255.255.255 and that all, not so ?? -Original Message- From: lwip-users [mailto:lwip-users-bounces+noam=silrd@nongnu.org] On Behalf Of mgirke Sent: Wednesday, November 09, 2016 1:48 PM To: lwip-users@nongnu.org Subject: Re:

Re: [lwip-users] elegant way to detect network connection

It is not that it wasn't clear before, it is that I did not understand... ;^) I do now. If there is a better way, I don't see it. I think your solution is preferable over toying with DHCP or ping flooding a router. ___ lwip-users mailing list

Re: [lwip-users] elegant way to detect network connection

Hi Sergio, Thanks for the reply. Let me explain it better. HDBaseT is a protocol developed by Valens LTD. This protocol is used mainly for extenders. There is an RX chip and a TX chip. The protocol is transferring video, audio, USB, RS232, IR and ETH over CAT5/6 cables !. As HDMI or other

Re: [lwip-users] elegant way to detect network connection

Hi Noam, I was about to say you could sniff how windows 7+ does it; but I don't think they would do it in an elegant, not even standard, way... ;^) I don't know if I get the whole picture, but I bet your problem is an "application ping". Do you actually need to know link is present or

Re: [lwip-users] Big time gaps in TCP communication

My suggestions: don't send pictures, post capture files explain who is the server and who is the client define "packet is lost", it is not normal to lose "packets"; what is your problem: frames getting lost or the retransmission time ? I bet the first one. explain the scenario in which you are

Re: [lwip-users] setting up multiple UDP connections with same prio and different data to send

Yes but Broadcast needs (just like multicast) the protocoll IGMP, which is the one my WLAN module doesn´t support. -- View this message in context: http://lwip.100.n7.nabble.com/setting-up-multiple-UDP-connections-with-same-prio-and-different-data-to-send-tp27709p27735.html Sent from the

Re: [lwip-users] setting up multiple UDP connections with same prio and different data to send

Hi, How about simple old broadcast ? Use one port for all, say 1. You do not need several tasks. If you want to simplify things use one task with on socket for receive. And another task with another socket for sending. As you do not need to connect (UDP), simply change remote_ip_addr
