OK, IM going a bit nuts here. New to the FPV world, learning (I hope) as I go, hopefully not F'ing things up.
iFlight Chimera7 Pro V2 O4 FPV BNF Drone why DJI 4.0 Air Unit and TBS Crossfire brand new from ProgressiveRC.
DJI Goggles 3 are bound. Battery with 24.93V on charger, plugged in to quad.
Goggles read DISARMED, Battery 4.08v, Link quality LOW 1-2, Air unit in low power state.
Problem is in binding my Tango II controller.
BLITZ F722 Flight Controller. Board lights: Solid Orange, green, red, flashing blue. Pushing the boards "Bind" button doesn't change this.
Controller: Tools: 02 TBS Agent Lite>Tango II XF> Bind
Binding> In Progress (spinning icon). Looks good. Board light still flashing blue.
Google Gemini tells me its updating the firmware.
It does this for ten minutes or so. Then the quad goes into an alarm state, with staccato beeping (3 or 4 beeps, short pause, repeat), motors jumping. (low voltage reading?), and I have to unplug.
What is going on?
