Unofficial shell script to list+download the Concept2 firmwares for PM5 monitors for rower/skierg/bike.
Technically it can also be used to download firmware for PM3 and PM4, but only the PM5 supports saving the files to a USB stick.
The script's functionality is similar to what the Concept2 Utility does:
- retrieve list of firmware versions that are currently available (stable and beta)
- delete the files that are currently in the destination folder
- download each of public or beta firmware files in that list and uncompress them
The script can save the files directly to the USB stick. Or you can save to another folder and manually move the files to the USB stick (.../Concept2/Firmware).
- jq - command-line JSON processor
- 7zip - file compression tools or another package that can unzip
7zfiles
For macOS:
brew install jq p7zip
- download the
getConcept2Firmwares.shscript and run it - script shows list of available firmwares and asks for confirmation to download them
- make sure the downloaded files (*.7z and the expanded files) end up on your Concept2 USB stick in folder
.../Concept2/Firmware
Parameters are available to specify the destination (e.g. directly to your USB stick) and what status the firmware versions should be (public or beta).
| parameter | default value | example |
|---|---|---|
-d <folder> |
$HOME/Downloads/Concept2/Firmware |
-d /Volumes/MYCONCEPT2USB/Concept2/Firmware |
-s [public | beta] |
public | -s beta |
-m [pm3 | pm4 | pm5] |
pm5 | -m pm4 |
Concept2 Utility uses authentication (basic auth) to get the list of latest firmwares.
That token is not included in this script and is left as an exercise for the reader.
The generic approach to get the token: by using a "man in the middle proxy tool" you can check what URL requests the Concept2 Utility makes and what authentication headers are sent. Authentication is only needed for getting that list, not for downloading the actual firmware.
Once you have the token you can store that in file .env or hardcode it in the script.
The format:
TOKEN="Authorization: Basic Y...U="./getConcept2Firmwares.sh -s beta -d /Volumes/MYCONCEPT2USB/Concept2/Firmwareall available pm5 firmware versions (public & beta)
