##spark core (heartrate)

To link a spark-core to your local cloud, do the following after installing the particle-cli:

1. Identify the spark core: press mode until blue > run particle identify
2. Put the spark core into DFU by pressing mode + reset, release reset while holding mode for about 3 seconds (until led flashes yellow)
3. Handle the server key: particle keys server default_key.pub.pem 192.168.2.1
4. cd into core_keys
5. Place core into DFU
6. particle keys save INPUT_CORE_ID_HERE
7. reset the core

You will need to flash the firmware (spark/pulsesensor-udp) to the spark-core:

1. particle compile core src/spark-pulse-udp --saveTo dist/spark-pulse-udp.bin
2. particle flash --usb dist/spark-pulse-udp.bin

javascript-workout's Issues

Heart Rate Sensors are wonky

Heart rates aren't accurate enough in the current demos when people are running. Look into a better way of connecting the sensor (glue ear lobe connector and attach to the ear instead?).

Connectivity issues on different subnets

On some networks traffic between the mobile devices and the computer doesn't work directly because they are on different subnets.

Look into an online solution (heroku) and route the traffic through there for the mobile demos?
