Faulty Powervision PowerEgg

Got my hands on one of these unique quadcopters.

Condition was unknown and so a risk, and it came with no battery which is a royal pain as getting batteries for this is only possible from Aliexpress.

Anyway once battery arrived , plugged it in a all fired up okay but it will not connect to the app and can now see why it came with no battery.

Got onto Powervision and they did reply back with a reset method to re bind the craft to the wifi repeater , but after many many times of trying it still wont connect.

I took the repeater apart and managed to solder on 3 wires and red the console in via UART. :-

I also managed to connect via UART to the main board on the PowerEgg  craft itself and there is a socket on the main mcu board on the PowerEgg thats labeled RX/TX/ GND.

And seems its based on the Pixhawk

I can see on the startup console that when I do a bind it says Link Success but does not show link on repeater or app.

But what I did notice was it has loads of errors on camera like:-

pv_camera: tx error -1

So I am wondering is there a issue with video from camera and fails to link to repeater and app because of that?

Because there is no video being sent????? Or is there a fault with the repeater or the Transmitter module on the Egg itself????

I am assuming as it uses Pixhawk and Mavlink that it wont say connected until it receives

Mavlink data.

Cant really go any further on this with out another one to compare it with.

So will just be a pretty ornament on shelf for now 😉
