Serves firmware binary files for Arduino (or ESP, ...) OTA projects.

• Generic delivery of firmware images based on naming scheme
• Self contained, pure Python
• SSL

./server.py --dir=/my-firmware-directory

The OTA-Server can be installed as a service, which means it will be automatically started in the background after a server reboot(currently the install script is only tested on raspbian):

./install.sh

The logs of the service can be retrieved via:

sudo journalctl -u ota-server

There is also a Docker image available on Docker Hub:

docker run -p 8000:8000 -v /my-firmware-directory:/firmware sglahn/ota-server

The server can be tested with, e.g. curl:

url -X GET \
  http://localhost:8000/firmware \
    -H 'x-ESP8266-version: 1.0'

Optional arguments:

  -h, --help   show this help message and exit
  --dir DIR    Directory containing the firmware binaries to serve. Default:
               ~/firmware
  --port PORT  Server port. Default: 8000.
  --log LOG    Log level. Default ERROR
  --cert CERT  SSL cert file to enable HTTPS. Default empty=No HTTPS

Firmware files can be served if they follow the naming convention

${project-name}-${version}.bin

Where both, project-name and version are Strings.

Example: Given a file with the name firmware-0.1.bin, this would be served via the URL:

http://{host}:{port}/firmware
