+=== rsync ===
+Configure datastorage with rsync in ''/etc/rsyncd.conf'' on ship laptop.

+run datatransfer task on each pi ( later triggered via script @ groundcontrol pc): e.g.
-  rsync -avvz -u --progress -h /data/bilder/ rsync://GROUNDSTATIONIP/camimages
+  rsync -auv --progress /data/bilder/ rsync://GROUNDSTATIONIP/ringo-05032020_0915h-cam-r
+Don't use the -z option which compresses the data. The images are already compressed and the CPU load will result in 1 MB/s transfer rate compared to 3-4 MB/s without the -z option. (Beck, 23.2.20)
+If you like to transfer and delete the images from the pi, use the --remove-source-files option.

+==== WIFI =====
+If Wifi isn't working, first check if the firmware file can be loaded!
+  dmesg | grep rtw_pci
+In Ubuntu 18.04 the firmware for rtw8822 wifi adapter (ASUS TUF FX505DV Laptop) isn't included in linux-firmware ubuntu deb package! So after a Kernel update it can be necessary to fetch it again and copy it to the lib folder.
+  git clone git://git.kernel.org/pub/scm/linux/kernel/firmware/linux-firmware.git
+  cp ./linux-firmware/rtw88/rtw8822c_wow_fw.bin /lib/firmware/rtw88/
+=== eduroam ===
+Eduroam does not work with the default wpasupplicant 2.6 version. I have made a backport of wpasupplicant 2.9 from Ubuntu 19.10.
+{{ ::wpasupplicant_2.9-1ubuntu2_amd64.zip | wpasupplicant package 2.9 }}
+You need to install that package. Please download from this wiki and unzip it.
+<code>
+sudo apt install libnl-route-3-200
+sudo dpkg -i wpasupplicant_2.9-1ubuntu2_amd64.deb
+</code>
+Check that the wpa supplicant service is running with
+<code>
+sudo systemctl status wpa_supplicant.service
+</code>
+In the Wifi Settings for eduroam choose in the "security" settings
+  * Security: WPA & WPA2 Enterprise
+  * Authentication: Tunneled TLS
+  * Anonymous identity: eduroam@hs-augsburg.de
+  * Check "No CA certificate is required"
+  * Inner Authentication: PAP
+  * Username: YOURUSERNAME@hs-augsburg.de
