What is the fastest way to download BIN logs over wifi?
Short question: What is the fastest way to download BIN logs over wifi?
I understand the bottleneck would be between the autopilot and the WiFi bridge. Why can’t this channel work as fast as the USB channel? I imagine the only difference would be an FTDI that must already be on the board connected to the chip’s serial port to provide a USB link.
I usually download .BIN logs via USB. Occasionally, when the logs weren’t big, I used to use SiK radios. However, now I need to download a lot of full flight logs, easily reaching 60MB each. After a long day of work, this could easily amount to 20 logs.
I found some related posts:
However, I understand that the focus is on the use of telemetry. I would like all the .BIN.
So far, my best results have been using DroneBridge with an ESP32. I used an external antenna and a baud rate of 500,000. Above this baud rate, there are many errors.
Here are some tests with a log of approximately 60MB:
USB cable + Mission Planner = 3 minutes for download it
USB cable + Mission Planner w/ mavftp = 2m:20sec
USB cable + QGroundControl = 3m:30sec
ESP32 + DroneBridge:
Mission planner = Manny errors catching the log. No good download in many tries.
Mission planner w/ mavftp : = Seems to have much more errors.
MavProxy download: 1 error on screen but a good download at 18.5kB/s. Almost 90 minutes to download.
QGroundControl: The best result so far. 30kB/s and a download in 40 minutes.
So, does anyone have a better approach to that?
Any good results using DroneBridge or similar wifi bridges with better baud rates than 500,000?
obs: These are my WiFi settings: (DroneBridge in this test)
