I think the mini has LiOns not LiPos...

Could be a bug they fixed that was dropping video when the signal was too low and now they changed the threshold of what too low is

Just speculating- but given that there is always a difference on when video cuts out vs when telemetry cuts out, it theoretically possible that they modified the threshold (signal strength etc) of when the video feed cuts out. I could even imagine a situation in which the calculation for the...

Yeah, agreed figured it was bogus...

Has anyone experienced this? https://dronedj.com/2020/10/15/dji-fly-update-reportedly-increases-mavic-minis-flight-range/amp/

How long did the process take end to end?

See this post in another thread re: concept of LTE control of MM - i posted a video of a guy running android 9 on pi4 which might not run fly but might run dji sdk - Concept: Mavic LTE controller with no physical mod

Actually looks like installing the version of android we need on Pi 4 is no problem. See this guy installing Android 9 (API Level 28) on Pi. We only need API Level 19 to run the DJI Mobile SDK Video of a guy installing Android 9 on Pi: DJI Mobile SDK requirements: Prerequisites - DJI Mobile...

I *think* Pi 4 can run the version of android we need to support DJI Mobile SDK Yes - mobile SDK would talk to the RC via USB since it is on the AC that is no prob. In your diagram the AC side would have the controller USB cable connecting the controller transmitter board to the PI. Ground...

Yes nice diagram. That is exactly what I'm talking about. And yes - use DJI's android SDK (same SDK used by dronelink / litchi etc.) running on android on the Pi. Might have to use a Pi 4 instead of a Pi Zero to support Android 19 which is what DJI MObility requires Also- ground station RC...

Great questions. Let me answer each one: - Power. How are you powering the attached RC board on the AC? Unsure on this one - need to research what the power requirements are of the RC board - How are you powering the Raspberry on the drone? PSugar battery should give it 4hrs and only weights...

Yeah for the Mini I am not proposing to mimic the enhanced wifi but rather to dissect a spare MM controller and pull out the board that interfaces with the USB cable and connects to the antennas - i am imagining we can lift that out and stick it on the drone along with the other components that...

Hey guys - I know there are a few posts on LTE possibilities, but I have a concept for a velcro-on LTE interface that would work with virtually all Mavic models and doesn't require any mods to the actual drone. Curious if you guys have any thoughts on why this wouldn't work: The design would...

Thanks! That's helpful, appreciate it.
