First ride on 4.21 and all seemed good. Cadence readings seemed good and free wheeling required in cadence and power reading zero within a matter of a few seconds.
I just figured out my problem. Operator error. All working fine now. 
4.21 as well. When free riding and at higher power levels I find the cadence measure is quite stable. Am very happy with it.
But⊠and maybe this is an edge case, cadence is all over the place when I am riding at low power levels during a workout in erg mode and while trying to maintain a fixed RPM⊠it is jumping between 60 and 90 RPM. I donât have that issue when I use a dedicated Wahoo cadence sensor.
Has anyone else seen this behaviour?
My cadence is stable at low power. Within 1-3 rpm

I have the exact same behavior. This is from a workout I did yesterday, where I started with the cadence coming from the Victory, then switched to a crank cadence sensor.
This has been happening ever since I got the Victory back in December, with all the previous firmwares. Donât really care much as the crank sensor is pretty reliable.

What?
A graph with no timeline and no explanation of which trace is which.
But we donât need either anyway if weâre meant to believe that both your devices report cadence in the 120 to 220 rpm range!
Well, I was replying to a comment about cadence changes during erg workouts, so the graph should be pretty obvious but apparently itâs not. 
The pink line is power, the yellow is cadence and itâs jumping between low 50s and high 90s until it stabilizes when I change the cadence source.

Exactly what Iâm seeing. Thanks for posting the graph.
Okay, but you talked about two cadence sensors, and then presented a graph with two tracks and a scale which you only just now admit wasnât anything to do with cadence.
I still have WiFi drop outs on firmware v4.21.
Garmin released an update for Neo 2, 2T (2T is only unit compatible with Zwift Ride) and 3M for virtual shifting and race mode. GP Lama review for Neo virtual shifting experience was off the chart. He said it was best virtual experience he has ever tested.
I wonder how many of us who sold our Neoâs for JBV will now sell their JBV and buy a Neo 2T again??
Thank god I kept my Neo 2t in my storage unit. Going to bring it back out and sell my JETBLACK victory or just keep it for backup

Again today dropouts with 4.21, about 23 minutes of the trainer being on, much the same time frame as my other 3 dropouts. Maybe JetBlack have managed to introduce the dropout bug Wahoo did all those years ago.

WiFi or BT?
Thanks,

wi-fi.

Just got my Jet Black Victory yesterday. Setup was smooth and everything connected ok. I just have to get a new heart rate monitor because it doesnât seem like Apple watches are supported by the Companion App any more. Not a huge deal for me.
My only question is about the firmware. Itâs showing that v4.51 is currently installed on my trainer out of the box, but that there is an update to 4.21. This seems counterintuitive to me that it would propose updating (or downgrading) to an older version number. Am I missing something here? I havenât updated yet for fear of breaking some functionality.
Thanks in advance for your help.
@fotomatt1 Heartcast app on phone works with the Apple watch to broadcast HR. Takes a few seconds to start/connect but it works well.

@chris_benten1, I did get Heartcast and it seems to work well, but Iâll still likely get a standalone HRM. My bigger question is about the FW version number, and weather 4.5 is an earlier version than 4.21?
Is it 4.5.1 or 4.51 ? If 4.51 I would keep it on 4.51
I am still having issues with Wi-Fi connection while on 4.21. Back to BT for me until next firmware release.
I also still have the cadence issue where it takes an absolute age for cadence/power to read ZERO when freewheeling. I am considering buying a separate cadence sensor to see if that improves things.
Firmware v4.22 released. I went back to Wi-Fi connection for first ride which was an ERG workout. No WiFi drops so will stick using WiFi until I notice a drop out.
Cadence/Power readings going to ZERO when free wheeling still seems to take an age. About 10 seconds. By that stage you are back pedalling.
Back to BT connection for me. I moved back to Wi-Fi after firmware 4.22 upgrade. Today I had planned a long indoor ride and I had connection issues. Went back to BT and connection was fine.
I reached out to JB support and they said they will either send me out a replacement PCBA out (Points towards a weak antenna) to me or I can send the unit back to UK support so they can replace it.
Has anyone replaced the PCBA themselves? Is the process ok to DIY? Did it address Wi-Fi issues?
In regards to cadence/power not dropping to ZERO when free wheeling I have order a cadence sensor. Should be here this week.
If both issues are not addressed by PCBA replacement and separate cadence sensor, then I am done with the JBV.
