This drone has great potential in my opinion, it definitely needs a firmware upgrade and in any case an accurate vision and calibration of some parameters.
Now I’m not an APM Planner expert, and don’t know where to start for the firmware.
I connected the drone via USB to a macbook and I started APM Planner 2.0.27-rc1, the software recognizes the drone and connects. Detect many parameters, from the logs I extracted the firmware version of the drone:
ACSimtoo V3.2.2I Mini Jul 19 2018
Surely it is a custom version of ArduCopter, unfortunately it has never been updated (there is a version around the net that does not seem to correct its problems).
Basically it has this problem:
Failsafe mode which is triggered very often even if the conditions are not met
Bad heading error
I hope someone can help me with the development and recovery of this drone, we would really do a favor to many enthusiasts who have bought it
Ardcopter 3.2.1 is the last version that supported the old APM Flight Controller so I suppose it’s a version of that FC. And you could be right about a custom version as there was no 3.2.2 official version. There may not be much you can do. What does the Flight Controller look like?
I’m looking into this too.
bit of info to add to the topic.
below is a screen shot of the port scan. port 50000 you can connect to mission planner via TCP over wifi
I’m guessing port 7070 is the video stream but I’m struggling getting anything form it. - it may be password protected feed I’ve tried wireshark but cant get any info
Application Processor, name already sanded
But after android reverse engineering, i assumed this Allwinner MR100
You can find more detail in Here and Datasheet

Hi @pendekar,
I have a “bricked” Simtoo XT175 linux board that I try to recover. I got USB connected and “working” on the DM and DP pins, but fail to enter FEL mode with all ways I could find (SD FEL boot image, short CL on NAND etc.). So, I try to dig into the MR100 datasheet, but your link isn’t valid anymore. I could only find general info here but no datasheet: MR100-breif -20210204 (allwinnertech.com)
Do you have an alternative datasheet link?
did you get anywhere with the camera, i just bought one for experementation as its the only low cost 5ghz wifi camera i can find. my chip wasn’t sanded down it uses the anyka ak3918en080 with the ar1021x dual band usb wifi chip. its shockingly good for the price.
