To cross flash the zyx firmware onto a cx, how are you guys de-powering The gyro? Unplug it from rx or do you have a switch in line?

Unplug the ESC. I know it would be helpful to have a third hand in this, but with some fiddling you can do it. Or, get someone else to press the set button while you connect the flight pack to ESC.

Frustrated!


Gaaaa! I must have spent at least 2 hours last night TRYING to get the bluetooth connection working. I performed the following steps:
1. Modded the USB cable swapping VCC & GND.
2. Powered up the gyro, and connected the cable (red light started flashing on the bt).
3. Searched for bt devices (found 'linvor').
4. entered the passkey '1234', computer 'paired' with the bt device.
5. Checked settings - it had 'serial over bt' as an available service via COM9.
6. I then tried putty, terraterm, etc, etc to get a connection on COM9, but NOTHIN I tried would make that light stop flashing!

Does anyone have any ideas?

Oh - and of course neither the Tarot software or John's would connect either.

Thanks - AC

I know this has been covered before but I couldn't find it , I updated one of my ZYX units to and using the ZYX 3.5 not the ZYX-s 3.5 update.

And now all I get is a red flashing light for a few seconds then no lights and nothing then.
Is there a fix for this or is it just bricked now?

Hi guys. I too have a question.

I have programmed my cx gyro using tx and had great luck. I am inthe process of rebuilding and i have a usb programming cord on its way.

Question is; when I connec the gyro the the pc software will it erase the data on the gyro? If not, will the software read and display my current settings?

Thx
Grant

@DR.M

When did you purchase your CX gyros that you cross flashed to zyx3.5?

I got mine in late Nov to early Dec (wife purchased for xmas gift last year so not exactly sure when) and i am wondering if this unit was made early enough to cross flash. Btw. It has the alum top with silver machined edge.

Hold the button on the gyro at power up (red led will flash), and then use John's app or the tarot v3 app to reflash it.

Edit: with John's app, open the firmware, select upgrade and then power up the gyro with the button pressed. The correct coms port must be selected.

No it wont erase the settings. The gyro will retain it's settings and display the current settings in the PC app.

I took it apart and when I opened the case the set button fell out in 2 pieces.

I can only guess that those pieces moved around inside and shorted the board out , as I only got the red LED to light one time after the update was installed.

Looks like the case is closed!

Bugger - that's a nuisance, there was one other guy that had a button fall apart ...

Did you use the v3.0 PC software?

edit: Then again, can't really do anything about a broken set button. Not sure if it would short anything, but it's probably too fragile/ broken or damn right tiny to easily replace or fix, right?

Has anyone tried putting the ZYX-S firmware on a non -S unit? I am wanting to try out the airplane mode.

Has anyone tried cross flashing the Tarot programmer update to a CX programmer?

I bought one of mine in Nov, and another in Feb. I've talked to a few people both here and on HF about crossflashing and I gather that CX gyros manufactured thru approximately Feb 2012 can be crossflashed, while those later ones cannot. Sale dates after Feb can be a poor indicator of whether it'll work or not, because the stock may have been from these first few batches.

I'm 90% sure yours should work.

I would really advise not to use John_nz software, there's really no point and as you've found out yourself it's only really making things more confusing.

Just stick with the official software, they are more stable.
