Solexious 0 Posted February 14, 2015 Share Posted February 14, 2015 hello all, Using energia with the tiva c launchpad and the included ethernetudp library, polling read doesn't seem to react to any broadcast packets (sent to 192.168.1.255 in my setup). Likewise sending packets to that address with udp.write doesn't get detected with my pc. Trying to dig though the energia source code to confirm if it's setup to allow send and receive of broadcasts. Anyone know? Best Sol Quote Link to post Share on other sites
Solexious 0 Posted February 15, 2015 Author Share Posted February 15, 2015 Digging deeper into this, if I start the Ethernet with a fixed ip I get the previous result, but if I start it with it obtaining an ip via dhcp I can now send out packets from my launchpad to 192.168.1.255. I've yet to test receiving broadcasts. Having to use hdcpd is an ok workaround, but for a correct operation I would need it to work when using a fixed ip...

Solexious 0 Posted February 15, 2015 Author Share Posted February 15, 2015 Confirmed, I can send and receive broadcast packets only if Ethernet is started with dhcp rather than fixed ip addresses. Any ideas as to what's causing this and a fix? Sol Quote Link to post Share on other sites
