FRstack 3 UDP Broadcast format ?

Options

Hi,

I'm trying to feed my Arduino based MagDeltaLoop system for 80/160 with the 6400 Slice's actual frequency and in this way want to autotune my loop.

I have setup/enabled UDP broadcasting in FRstack. I see packets sent using a sniffer and being received/decoded by the Arduino shield.

Q: what is format of the content format of these UDP packets?

Thanks in advance,
73, Kor - PA0KDV.

    XML:

    Here is an actual packet from my FRStack.

    <?xml version="1.0" encoding="utf-8"?><RadioInfo><app>FRStack</app><StationName>Maestro</StationName><RadioNr>2</RadioNr><Freq>43127471</Freq><TXFreq>43187471</TXFreq><Mode>FM</Mode><RadioMox>OFF</RadioMox><FocusRadioNr>3</FocusRadioNr><ActiveRadioNr>3</ActiveRadioNr><ActiveRadioMox>OFF</ActiveRadioMox></RadioInfo>

    Hi Kor, there is an Arduino library for Flex written by Enzo, IW7DMH. This makes it easy to get information from the radio. I have modified it to work with V2.x and V3.x. It does require a TCP/IP connection, so the Arduino Due and ethernet shield work great for this. For less cost and higher performance, the Teensy 4.1 from PJRC is the best choice.

    With this library, you can go directly to the radio, and not have FRStack as a middleman.

    I plan on making my version of the library available on GitHub today or tomorrow. If you decide to go this route, I would be happy to help you to get it working.

    73,

    Hi Len,
    I have been trying to Enzo's stuff but so far not able to connect to the 6400. His Tes01 example returns UDP data, but the IP adress returned is different from what the UDP packet says. See below capture.

    Can you share your updated library that you are using in your project?

    Thanks for your help.

    Hi Kor, well, it looks like you are making good progress! I just sent you the libs that I modified to your QRZ.com e-mail. Note that they are for a Teensy 4.1 board, not an Arduino so I don't know if they will work or not. The NativeEthernet.h library is strictly for the Teensy 4.1, Arduino uses Ethernet.h. The only change is to the NativeEthernet.cpp file - I changed the time out from 60000 to 6000 (from 1 minute to 6 seconds).

    When you start your Arduino, do you already have SmartSDR running? If not, that might explain the IP addresses.

    Here is what I get when I connect (I have probably got some additional print statements in there from when I was debugging):

    === Started DHCP request
