Custom ANT Broadcast using GenericChannel

And seriously, This is phenomenal. Thank you so much

Ok, good luck!

I'm kind of curious how you will test this and use it in practice tho. Is there an existing "ANT broadcast receiver" app that will receive your messages?

I kinda feel like that's something you'd have to write yourself, as well.

You have no idea how much clearer you have made my entire understanding of ANT and ANT+, thank you so much

This is for a school engineering project. (I'm in the PLTW EDD senior design project class). I have some documentation for it on the deployed IQ store and on my website (though the website discusses using BLE, it is outdated and I am using ANT):

Side note: I'm using the openant Python library to communicate to the watch. I have an ANT usb stick.

In a nutshell of what I'm doing:

Essentially my project is a workout assisting timing system for coaches to be able to
 have their athletes enter their names on their watch and connect to the system so that the runners can run on a track
but never have to manually lap or stop their watch. (This will come later).

What the watches are doing is exactly the same function as a race bib in a 5K or marathon event, but it elmininates the waste of using bibs in those races, instead making the watch act as the mechanism to both identify and act as a signal for the system to read and mark lap times and finish times.

So I'm using the Garmin watches as transponders for the system to record times. 

Another feature to come soon is the Pi will broadcast the recorded times back to the watches, so you can guarantee that the time recorded on the system is the same as the time on your watch. 
The idea is it will allow workout coaching to be much smoother and faster, just set up your data field (only once, can be used always after), then the predefined ANT signals will match with the Pi system, and you just start your watch, do the workout and the Pi system will track all 8 athletes lap and finish times (8 because those are my general constraints.)

Right now I have an entire Raspberry Pi Tkinter project built already, which has a timer and all the built stuff on it. The whole project is on my GitHub, mostly in python, if you're curious to check it out.

Again, thank you so much for helping! I've been struggling to get the ANT to work.

Such a helpful response deserves a detailed explanation of what i'm doing :)

No worries! Thanks for the detailed overview - that's a really interesting project.

Tbh I'm not sure if my sample code does exactly what you want yet, but hopefully it's a start.

One thing that maybe should be changed in the example is the default radio frequency of 2 (2402 MHz).

I see that CIQ uses a default of 10 (2410 MHz). I have no idea if this corresponds to any kind of "default ANT frequency" or if it's arbitrary. but I guess it wouldn't hurt to use the default. Obviously whatever you choose has to match whatever you're using on the receiver side in any case.

See the DEFAULT_* constants here:

I did change it. Right now I've programmed my Pi to listen for signals at channel 66, and I changed the RF in the data field to as well. Still didn't work, however. Something I should probably find out, however (I just realized this and I may be screwed), is whether or not the Dynastream ANT+ adapter also supports ANT... Do you know if they do?
