script to download the Concept2 firmware files similar to what Concept2 Utility does
#!/bin/bash
# UNOFFICIAL script to download the Concept2 firmwares for PM3/4/5 monitors for rower/skierg/bike
# similar to what the Concept2 Utility does: first retrieve list of available firmwares and then download them
# optional parameters
# -d <folder> e.g. /Volumes/MYCONCEPT2USB/Concept2/Firmware (default: $HOME/Downloads/Concept2/Firmware)
# -s [public | beta] (default: "public")
# --------------------------------------------------------------------------------------
# Concept2 Utility uses basic auth to get the list of latest firmwares
# to find the token use e.g. https://mitmproxy.org/ or ProxyMan and run Concept2 Utility
# look for request to https://tech.concept2.com/api/firmware/latest
# you can store the token in .env or put it in this script
# --------------------------------------------------------------------------------------
[[ -f ".env" ]] && source .env
[[ -z $TOKEN ]] && TOKEN="Authorization: Basic Y...U=" # <<< CHANGE HERE OR IN .env FILE
