When I attempt to run my program I get the error: ANT+ USB stick not found! /home/pi/ant-plus/build/ant.js:522 this.outEp.transfer(data, function (error) { ^

any help will be greatly appreciated. MIke

There's at least two differing ANT+ stick ID codes - I have an old Garmin ANT stick (the long one, not the short stubby type) so had to change the coding in at least one of the files as it appears to reference the stubby one. Otherwise you do get the can't find stick error.

For what it's worth, though I got it all working in the end (the debug output showing the treadmill speed correctly), the ANT transmission of this failed to work - Zwift would pick up and pair to the device ID in the pairing screen okay, but 99% of the time the speed remained at zero. Very rarely Zwift would pick up the speed for about a second, then lose it again. I tried everything I could think of, moving the ANT sticks closer together to rule out interference/loss of signal, but the issue remained. I gave up in the end, which is a shame as it would have been great if I could have got it to work.

Hey Rob, I was able to get my USB Stick found by editing the GarminStick3 to GarminStick2.

It looks like I am in the same boat as you.....Zwift pairs and connects AOK, but speed at 0.....once in a while Zwift will pick it up, but primarily stuck at 0.

I will continue to test and troubleshoot. If I get it going, I will post back.
