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.

1. Insert the ESP into the pixracer.
2. Download the latest Dailybuild from QGroundcontrol: https://docs.qgroundcontrol.com/en/releases/daily_builds.html
3. Download the latest firmware for mavesp: https://github.com/dogmaphobic/mavesp8266
4. Login into pixracer WIFI which is provided by the ESP
5. Open http://192.168.4.1/update and flash the downloaded firmware
6. Optinal: Set Params https://github.com/dogmaphobic/mavesp8266/blob/master/HTTP.md
7. Optinal: Set WIFI Channel via http://192.168.4.1/setparameters?channel=11 (Here Channel 11)
8. Optinal: Restart ESP as only then the new params will be used
9. Open QGroundcontrol and download dataflash Log

Test 14.2.2020

1. Qgroundcontrol Dailybuild 14.2.2020
2. Mavesp Firmware 1.2.2
3. ⇒ Speed about 15-20kB/sec
4. 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

Idea is to download the dataflashlog via Serial Telemetry Link from the Pi from the Pixracer

1. Wire RX / TX with the PI
2. Install MAVProxy @ PI : sudo pip3 install mavproxy
3. Set Telemetry Speed (115200 / 900000) via QGroundcontrol
