Multicasting from TIVA (TM4C1294XL)

user4829556

Other Parts Discussed in Thread: ENERGIA

I am working on a project that uses TIVA as an interface between hardware and software. For this purpose I am using ipMIDI for sending and receiving messages from TIVA. The problem I had is that the UDP library from the IDE (energia) has no support for multicasting. Hence I can send messages to the multicast address, but I am not able of receiving them by listening to the multicast port.

Do you know if there is a way for implementing UDP Multicast in TIVA?

What is your experience regarding this issue?

Thanks.

Hello user4829556

Not sure what you mean here. You can send multicast packet but not listen to them & IDE does not support multicast. Sounds conflicting statements.

Yes. Sounds conflicting but curiously I just can send (not listen) to the multicast address using the Ethernet library:

Udp.beginPacket(multicastIP, multicastPort);
Udp.write("hello");
Udp.endPacket();

My problem is that I can't use this for listening to the multicast coming from ipMIDI:

UDP.beginMulti(multicastIP, multicastPort) ;

It seems that this function is just supported by Arduino and not TIVA (with the energia IDE). I tried to use the Ethernet library of Arduino, but it fails to compile.

Hello user4829556

I would suggest then moving away from Arduino/Energia and instead using the TivaWare. The following reference design application example shows how to listen to a broadcast message on a port.
