====== 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. If not other noted, the baudrate is set to 115200. === Method1: Download via MavEsp WIFI === - Insert the ESP into the pixracer. - Download the latest Dailybuild from QGroundcontrol: https://docs.qgroundcontrol.com/en/releases/daily_builds.html - Download the latest firmware for mavesp: https://github.com/dogmaphobic/mavesp8266 - Login into pixracer WIFI which is provided by the ESP - Open ''http://192.168.4.1/update'' and flash the downloaded firmware - Optinal: Set Params ''https://github.com/dogmaphobic/mavesp8266/blob/master/HTTP.md'' - Optinal: Set WIFI Channel via ''http://192.168.4.1/setparameters?channel=1'' (Here Channel 1 - At HS Augsburg least occupied Channel) - Optinal: Restart ESP as only then the new params will be used Test 14.2.2020 - MAVEsp in AP Mode - Qgroundcontrol Dailybuild 14.2.2020 - Mavesp Firmware 1.2.2 - Login into pixracer WIFI which is provided by the ESP - Open QGroundcontrol and download dataflash Log - => 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 Test 15.2.2020 - MAVEsp in Station Mode - Login into pixracer WIFI which is provided by the ESP - Set MAVEsp to Client / Station Mode: Mode = 1 . Be sure to type in the correct AP Name and Password. I tested by giving static IP - Set Params via HTTP Interface: ''http://192.168.4.1/setparameters?mode=1&ssidsta=APNAME&pwdsta=PASSWORD&ipsta=192.168.8.44&gatewaysta=192.168.8.1&subnetsta=255.255.255.0&reboot=1'' - Start QGroundcontrol - Connection should be established automatically - Download dataflash Log - Speed about 18kB/sec === Method2: Download via UART-MAVProxy to Raspberry === 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 / 921600) via QGroundcontrol - start pi<->pixracer connection : ''sudo mavproxy.py --master=/dev/ttyS0 --baudrate=921600'' - get log list : ''log list'' - download log: ''log download '' Test 15.2.2020 - ''log download 1 1.bin'' - => RTL> Finished downloading 1.bin (473553 bytes 48 seconds, 9.8 kbyte/sec 143 retries) Test 20210529 CM4 - ''mavproxy.py --master=/dev/ttyAMA0,1500000'' - Baudrate 1500000 - Finished downloading log1.bin (232633 bytes 10 seconds, 21.7 kbyte/sec 0 retries) Test 20210617 Pi0: - ''mavproxy.py --master=/dev/ttyS0,115200 --default-modules log'' - Baudrate 115200: Finished downloading log1.bin (232633 bytes 29 seconds, 7.9 kbyte/sec 0 retries) - Baudrate 500000: Finished downloading log1.bin (232633 bytes 17 seconds, 13.7 kbyte/sec 0 retries) - Baudrate 921600: Finished downloading log1.bin (232633 bytes 13 seconds, 16.8 kbyte/sec 0 retries) - Baudrate 1500000: Downloading log1.bin - 232560/232633 bytes 100.0% 10.1 kbyte/s (100 retries 57 missing) Test 20220531 CM4: **Baudrates** **115200** * Unordered List ItemFinished downloading log1.bin (55289 bytes 6 seconds, 8.7 kbyte/sec 0 retries) **500000** * Finished downloading log1.bin (55289 bytes 3 seconds, 16.3 kbyte/sec 0 retries) **921600** - log download 1 - - Finished downloading log1.bin (55289 bytes 3 seconds, 16.1 kbyte/sec 0 retries) - Finished downloading log1.bin (55289 bytes 3 seconds, 16.2 kbyte/sec 0 retries) - Finished downloading log1.bin (55289 bytes 3 seconds, 15.8 kbyte/sec 0 retries) - Finished downloading log1.bin (55289 bytes 3 seconds, 16.1 kbyte/sec 0 retries) - Finished downloading log1.bin (55289 bytes 3 seconds, 16.5 kbyte/sec 0 retries) **1500000** * Finished downloading log1.bin (55289 bytes 3 seconds, 16.9 kbyte/sec 0 retries) * Finished downloading log1.bin (55289 bytes 3 seconds, 17.0 kbyte/sec 0 retries) * Finished downloading log1.bin (55289 bytes 3 seconds, 16.9 kbyte/sec 0 retries) * Finished downloading log1.bin (55289 bytes 3 seconds, 17.0 kbyte/sec 0 retries) * === Method3: Download via USB-MAVProxy to Pi === Test 27.5.2021: CM4/Pi4 - Finished downloading log3.bin (13292972 bytes 60 seconds, 219.2 kbyte/sec 0 retries) Test 28.5.2021: Pi Zero - Added usb connector as described in [[https://www.instructables.com/Raspberry-Pi-Zero-OTG-Hack-Add-a-Fullsize-Connecto/|HERE]] {{ ::signal-2021-05-28-170257.jpeg?400 |}} ''mavproxy.py --master=/dev/ttyACM0,115200'' - loads all modules of mavproxy => 100% idle cpu - Finished downloading log2.bin (462481 bytes 35 seconds, 13.1 kbyte/sec 0 retries) - Finished downloading log2.bin (462481 bytes 46 seconds, 10.0 kbyte/sec 0 retries) - Finished downloading log2.bin (462481 bytes 64 seconds, 7.1 kbyte/sec 0 retries) ''mavproxy.py --master=/dev/ttyACM0,115200 --default-modules log'' - loads only log module of mavproxy => 60% idle cpu - Finished downloading log1.bin (232633 bytes 8 seconds, 26.9 kbyte/sec 0 retries) - Finished downloading log1.bin (232633 bytes 8 seconds, 26.9 kbyte/sec 0 retries) - Finished downloading log2.bin (462481 bytes 17 seconds, 26.9 kbyte/sec 0 retries) Test 20210529: Pixracer @ Laptop ''mavproxy.py --master=/dev/ttyACM0,1500000 --default-modules log'' - Finished downloading log3.bin (13292972 bytes 50 seconds, 264.3 kbyte/sec 0 retries) - Finished downloading log3.bin (13292972 bytes 49 seconds, 270.3 kbyte/sec 0 retries) Test 20210529: Pixracer @ CM4 ''mavproxy.py --master=/dev/ttyACM0,1500000 --default-modules log'' - Finished downloading log3.bin (13292972 bytes 53 seconds, 249.2 kbyte/sec 0 retries) - Finished downloading log3.bin (13292972 bytes 53 seconds, 249.3 kbyte/sec 0 retries) === Method4: Download via QGC === Test 28.5.2021: QGC @ Laptop - ~250 kbyte/sec
