DataFlash Log Downloading Tests
As the plane is closed we cannot download the dataflash logs anymore by removing the SD-Card from its slot.
Therefore a wireless method need to be found to get the data from the pixracer.
Method1: Download via MavEsp WIFI
- Insert the ESP into the pixracer.
- Download the latest Dailybuild from QGroundcontrol:
- Download the latest firmware for mavesp:
- Login into pixracer WIFI which is provided by the ESP
- Open and flash the downloaded firmware
- Optinal: Set Params
- Optinal: Set WIFI Channel via (Here Channel 11)
- Optinal: Restart ESP as only then the new params will be used
- Open QGroundcontrol and download dataflash Log
Test 14.2.2020
- Qgroundcontrol Dailybuild 14.2.2020
- Mavesp Firmware 1.2.2
- ⇒ Speed about 15-20kB/sec
- Estimated Time to Download One Flight: Pixracer creates 3.4 MB/Min ⇒ 204MB/h = 204MB/Flight ⇒ 204MB / 0,020MB/sec = 10200 Sec = 170 Min = ~3h
Method2: Download via MAVProxy to Pi
Idea is to download the dataflashlog via Serial Telemetry Link from the Pi from the Pixracer
- Wire RX / TX with the PI
- Install MAVProxy @ PI : sudo pip3 install mavproxy
- Set Telemetry Speed (115200 / 900000) via QGroundcontrol
