3.1 Trackers
The trackers would typically be attached to the right and left clips and then mounted on the side of the user's trainers. The
right tracker is designated as the master and the left tracker is designated as the slave. The master connects to the slave and
also to a phone for configuration and data offload.
The ON/OFF button is located on the rear side of the trackers. To switch on the units, push and hold the switch for 3 seconds
before release. A blue light will show monetarily followed by a series of 5 green flashes indicating that the unit is now
powered on. To switch off the units, push and hold the same button for 3 seconds. Upon release check a red light is seen
which then extinguishes.

Figure 2: power button
Both trackers operate in the ISM band (~ 2.4GHz –2.5 GHz). The right tracker supports Bluetooth Low Energy (BLE) and ANT,
whereas the left tracker only supports BLE. Additionally, the left tracker has a GPS receiver which receives signals in the
1.575GHz range and has an Rx sensitivity of -165dBm.
During a run, the left and right tracker continuously exchange data over BLE in order to determine the user’s running metrics
(e.g. speed, distance, cadence, etc). If an accompanying phone is used during a run, the relevant data is sent over BLE to the
phone so that the user is notified of his/her running metrics. When ANT functionality is enabled, the right tracker uses the
ANT+ SDM profile to broadcast the data to ANT+ displays.
4. Charging
If the trackers need charging, they can be plugged into the supplied charger which is powered from a standard USB port or
USB charger. During charging, a pulsating red light will be seen. Once charged, the red light turns green.
