Pairing Tacx T2022 remote with GC #5

Hello Totalreverse,
I have read your document about the Tacx protocols and I have the following issue.
I train with a Tacx T2080FC package, including Genius Smart trainer, T2028 antenna, T2022 remote and TTS4 software. I now wish to switch to Golden Cheetah. I was able to pair the trainer and the HR monitor (Garmin HRM1G Ant+) but not the T2022 remote. Is that remote compatible with GC or do I have to buy another one ?
Any advice ?
Thank you.

T2022 does not talk a documented standard ANT+ protocol.
I am fairly sure, that GC does not support it.

Cursor Control (Genius interface) T2022 ANT parameters are:

Device-Type = 0x55
Transmission Type = 0x01
Channel 60 = 0x3c
Channel period 0x1000 = 4096 (8 Hz)
Default Network Key (= "no" network key)

If you setup the ANT receiver with these parameters you should receive "0x4e" data frames with byte #2 containing 4 bits for "Up","Down","Left" and "Right".
Byte #1 may contain the HR signal from a non coded 5.3 KHz heart rate monitor (but this is not confirmed).

Hello Totalreverse,
First, thank you for your fast reply and your advice.
Unfortunately, I have absolutely no talent and no expertise to perform that kind of modification.
Do you think that I can make GC work with a Garmin Edge remote ?
There are 3 buttons on this remote. The only functions that I need is to start and stop the training session, and increase and decrease the intensity while I am on the bike.
By the way, another question: is the Watt value indicated on the GC display reliable ? I have the feeling that for the same wattage, I work a little less hard on GC compared with TTS4.
Thank you.

"Thisisant" indicates, that the Garmin Edge remote control supports the ANT+ "generic control" protocol (https://www.thisisant.com/directory/edge-remote-control). Maybe this is already supported by GC.

The first thing you shouid try, if you want to start development for GC, is to build the binary from the unmodified GIT sources on your system. I am fairly sure, that this will be frustrating at the first time.

The Genius Smart trainer supports the ANT+ FE-C protocol. I don't think there is a difference between TTS4 and GC as long as you run the same mode - i.e. the "target power" based ergo mode. There is also a "basic resistance" and a "simulation" mode. In simulation mode, additional parameters (should) have an effect on the total resistance i.e. your configured "user/rider weight".
