[REQ] DIRCON Client

[IProgrammedOnce]

Useful to avoid using bluetooth and also for research.

[IProgrammedOnce]

Here is some capture data which I hope can help.
A short 50 second workout of 10 seconds each of 100, 110, 120, 130, 140 watts using ERG. The watts did jump around a bit.
The folder has serial capture and Wireshark capture of the dircon adapter .88 and the laptop .29

Watt 95 so 0x5F, so it's the 13th and 14th byte

02 68 50 0b 11 00 00 44 00 6e 0b c6 00 a0 01 64 03

wattage is right here 0x1a0 = 416
cadence could be the byte after 64 = 100
speed is 0xb6e = 2926 so 29.26

@IProgrammedOnce everything is very clear!!!

02 68 50 13 08 00 00 34 00 a0 01 b0 ee c3 0d 00 00 9b ab 79 05 11 7c 07 03

on this frame i don't know which other values are coming through

[IProgrammedOnce]

Some more log files. Hopefully the names explain.

On 2 I was still wearing my HRM belt and had it in use on Zwift but disabled it in QZ.

On 2 I had real dircon selected in Zwift for all categories except HRM.

On 1 I had only cadence for real dircon so that the dircon serial data would be active. Hopefully it is all or nothing and it doesn't send just cadence but that will be interesting to see as well. Power and Controllable were QZdircon.

Hopefully this will allow some compatibility.

first session with parser! watt and speed both work, cadence is wrong

[cagnulein]

cadence fixed @IProgrammedOnce :)
