OTA over SCP
How to setup and configure "OTA over SCP" upload for PlatformIO. The uploader pushes .bin files to remote OTA server using SCP. Images can be served to Sonoff-Tasmotas from there.
To upload .bin images to OTA server using SCP, one has to edit following lines under target environment:
; *** Upload file to OTA server using SCP
upload_port = pi@192.168.2.11:/var/www/html/Updates
extra_scripts = pio/sftp-uploader.py
upload_port should be modified to reflect user, host and path on the host where images should be uploaded.
SSH communication between the build server and OTA server should be pre-configured so that it doesn't require password (pre-shared keys).
On a linux client machine type the following to generate the key:
ssh-keygen -t rsa -C "YOUR OWN KEY INFO"
Press enter three times (without any input).
Copy the key to your ssh server:
ssh-copy-id -i ~/.ssh/id_rsa.pub USER@IPADRESS
You need to confirm this action. Use your server ssh password (one last time).
Optional reload the ssh service:
sudo /etc/init.d/ssh restart
Easy compilation and upload can be performed from the icons at the laft side of the PlatformIO screen or use Ctrl + Alt + U to upload (will build if needed).
