Hi all. I am trying to understand what has changed in Garmin's ANT+ communication between devices. The best I have been able to determine, older stuff doesn't communicate with newer stuff. I found the article below and a call to their support team confirmed as much but without any further details:
https://support.garmin.com/en-US/?faq=IEKqXfw9Co47DCkI5xtV2A
The support person confirmed but indicated that engineering did not tell them why. Also, I was unable to determine how Garmin determines "older" and "newer". You think a date or version number may be of use, but alas.
Any help understanding this is appreciated.
