| + | 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. | ||

| + | |||
| + | Check if folder on receiverside exists. | ||
| + | |||
| + | To get an idea whats the cause of the error - checkout rsync service status on receiverside (laptop): | ||
| + | |||
| + | sudo systemctl status rsync | ||

| + | ==== 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:// | ||
