hey guys
i made a projekt that samples audiodata and send it over ethernet using the rtp protokol. i used the teensy 3.6, the adaptor board and the wiz820io module. the incoming data from the audio adaptor board seem´s to be fine. packing the data into a simple rtp frame works. but when i initialize the ethernet library the data from the audio objekt may be corrupt. changing the position of ethernet.begin() may no effect.
bevore i initzialize the ethernet with ethernet.begin() the rtp data seems like this:
the first 12 bytes is for the rtp header. after that comes the data.
after ethernet.begin() the data seem´s like:
i look a fews days in the ethernet library and my code but i can´t find out what happends. i think that somewhere in the ethernet library overwrite the audio data from the audio library. my code you can found on https://github.com/sourceforge807/RTP-Audio
i used the audio and ethernet library which was included in the arduino software. i hope that were all informations you need.
regards
