ANT Forum

I am bridging a wired smart trainer to an ANT+ dongle. I need to provide the trainer with user configuration information such as rider weight. I request the User Configuration Page (55) using my Specific Trainer Page (25) and the flag Trainer Status.


I send Specific Trainer Page (25). Here it is raw:
19 01 00 00 00 00 40 30

This is my interpretation of the above data:
19 Page Num (25)
01 Event Count
00 Cadence
00 Accum Pwr LSB
00 Accum Pwr MSB
00 Inst Pwr LSB
40 0 = Inst Pwr MSN 4 = User Configuration Required
30 0 = Flags Bit Field 3 FE State Bit (In Use)

I get no response from the Open Display.
Note that in the documentation for trainers on page 78

In addition, this page should be transmitted to a trainer when user configuration bit of the flags bit field in the
trainer speed and resistance page is set (section 7.6.7).

It says the "flags" bit field, but the "User Configuration Required" is in the "Trainer Status" bit field.

Am I diddling the wrong bits? What is the correct way request a user configuration page from the open display?      

Ok so my code is right. Other trainer software sends me Wind Resistance (Page 50) and User Configuration (Page 55). For some reason Zwift does not provide this.

Perhaps it is because I am using Development ID as the manufacturer (0xFF).

Any ideas as to why Zwift would not give Wind Resistance and User Configuration but would give Track Resistance?
