Okay...let me break apart all this. For the first part, Yes I know that DJI will be releasing a SDK (Software Development Kit) for the
Mini 2 (Just trust me on this). This is used by third parties to integrate into DJI's system and develop software to be used with it's drone. The
Mini 2 is recent, so a SDK for it I will suspect will be in first quarter (Which we are in now) or First of Second Quarter (April..ish) From there about 1-2 months max for third parties to intergrate feature set.
Just so you know, the SDK for
Mini 1 and
Mavic Air 2 was released and some companies had software out the next day
Litchi is the largest seller and as such they like a bit more Beta time usually, this may or may not be the case..so not holding anything on that system..but I fly Litchi and have done so for 5 years.
Okay...... Follow me. This is done by your Drone AND the device GPS systems....so with that it had to be in the Drone Firmware from the start. This was in all DJI Drones in the past but function was...ehhhhh... as far as framing and it kinda lagged behind and sped up..kind like a slinky or spring type thing. So DJI discontinued that with the advent of Optical Tracking.
Optical Tracking uses the main camera and normally the power they added for computers in the Drone to do such way back in the end of 2016. It was built into the drone software and available out of the box, no third party required. Third party developers then added it in for the older aircraft that just had the old "Follow me" mode. So that is how that got started.
It didn't work all that great either back then and would routinely lose the tracking object (DJI factory one as well as 3rd party) Improvements to systems and
tracking algorithms have advanced with different models and through the years with the
Mavic Air 2 having DJI's latest improvements. Sadly
Mini 1 and
Mini 2 do not have those systems in place due to weight issues for such. So that brings us back to the Device and third Party route of doing it. So not going to be as robust as a factory system in aircraft like I fly, but it will get you though some basic tracking and such. There is one (non DJI) that is king of object tracking and object avoidance had that be your thing, but it lacks in other areas...so yeah...there are options depending on how bad you want to track, do you need it to avoid and move and climb perfect ( or reasonable so for today's tech)or just give it a good college try
So depending on your level of "want" on the tracking combined with Object Avoidance capabilities while doing so is going to 1. influence what drone you buy and how much you spend on that end
. And 2. Which Device you may need and money you spend on that end to control the whole thing.
Your in a special blend of people that "want their cake" kinda crowd. You want advanced feature set, but really don't want to spend major money to get it situation. You really need object detection when using tracking, unless your out in the middle of a open field with nothing but grass, or are extremely mindfull of any object around you
. Even the
Mavic Air 2 isn't the best as it has limited O/A (Object Avoidance) even though it has the best (At present) tracking system known as APAS (Advanced Pilot Assistance System) that DJI has. Which tracks by subject (it knows people, cars and some stuff and tells you that
) when you lock on. Interesting enough it doesn't know sail boats...and can't track them accurately...but I digress.
We are now awaiting the
Mavic 3 series (top of the line..more or less) that will tie all into one drone for DJI....but that will be around $2000 with all bells and whistles (I am assuming)
. I hope I have you up to speed and thanks for reading....class dismissed.
Finally...your gonna be hard pressed to get a system that I "think" you want with a device to do it at the price your hoping...your gonna have to go up a bit for a reliable middle IMHO. So I am saying
MA2 with a really nice used apple...ehhh around i8 or used Mini 5 tablet. Again just my years of doing these things...Your mileage may vary and you might be happy with a
mini 2 and your used i6 phone.
