Pair Your Polar Bluetooth Smart Stride Sensor With Fitdigits

Fitdigits is now compatible with the Polar Stride Sensor, the first Foot Pod to use Bluetooth Low Energy/Bluetooth Smart, as well as other BLE stride sensors. The Foot pod will work with all Bluetooth Low Energy compatible iOS devices. First, you need to install the Stride Sensor. Once you have done so, you are ready to pair. To do so:

  1. Stomp your foot a few times to activate the sensor
  2. On your BLE compatible device open your Fitdigits App
  3. Go to Settings -> My Sensors, and under Foot Pod turn “Bluetooth Smart” to ON

The Stride Sensor should pair immediately. Once it does, just begin a workout and you are good to go!

Troubleshooting Your Heart Rate Monitor & Other Sensors

#1 Issue – Low Battery 

Test the battery, and if necessary replace it. Low battery can cause strange data including abnormally high or low readings. Within our app, after changing the battery, you will need to trash the sensor and pair again. If battery replacement does not fix your issue, try the following tips:

Polar H7 or Other BLE (Bluetooth Smart / Bluetooth Low Energy / Bluetooth 4.0) Compatible Heart Rate Monitor

  • Paired With Another iPhone : Make sure no other iPhone is currently connected and communicating with your BLE heart rate monitor. If the heart rate monitor is paired with another iPhone, you will not be able to use the HRM
  • Close Other Paired Apps: If there are any other apps on your iPhone that are communicating with your BLE heart rate monitor, terminate them. The HRM will only be able to pair with one fitness app at a time.
  • Lots More Tips:

Foot Pod (iOS)

  • Activate: Tap your foot in a running motion to activate the foot pod.
  • Installation: Ensure the arrow on the foot pod is facing your toes.

Speed and Cadence Sensors (iOS)

  • Activate: Rotate the pedals a few times to activate the sensor before pairing
  • Choose Sensor: If you are using a Spin Bike make sure you are using a Cadence Sensor. For an outdoor bike, use a Speed and Cadence Senso
  • Installation: Proper installation including positioning of your spoke and pedal magnet as well as the arm distance from spokes is very important.

Note: It has been reported that some HRMs, such as the Wahoo TICKR belt, might have issues due to the belt having both cadence and heart rate. Trying to pair cadence sensor after pairing the HRM caused trouble. The solution was to pair the cadence sensor first, then the heart rate monitor.

Foot Pod / Stride Sensor Setup & Calibration

Having a foot pod can make life a lot easier. You do not have to worry about a poor GPS signal, plus you get the valuable number of strides and cadence. To pair your BLE compatible foot pod (otherwise known as a stride sensor) with your Fitdigits apps:

  1. Tap either the main menu (three bars in the top right) then Sensors, or on the home screen, tap the gear options icon, then Manage Sensors.
  2. With the foot pod installed (see the manufacturers suggestions and instructions) and tapping your foot (to “wake up” the sensor), turn the Bluetooth Smart switch in the Foot Pod section to ON.
  3. You should see a successful pairing notice like shown below, and then see the foot pod information just below the ON button in that section.  To access more information, delete the pairing, or turn on GPS options with the foot pod, tap the name of the foot pod. See below on Calibration for more.

Calibrating the Foot Pod / Stride Sensor

One thing about food pods / stride sensors, however, is that they are not perfect. Just the other day, I caught mine lying about my distance.

A foot pod can be calibrated to fit each person’s stride length. A foot pod is automatically set to estimate distance based on an “average” stride and height, but for everyone else, your foot pod distance can be a little or a lot wrong. For example, if Shaquille O’Neil used the same foot pod, I think The Big Diesel would have strides a bit bigger than Mini-Me’s, leading to drastically inaccurate distance readings. There is also the idea of “average” stride – I’ve found, even after calibration, at times the distance can be a bit off – like in the hills when the stride is shorter. Not much, but a bit.

Still, in terms of a smooth pace (especially useful for pace-based routines), faster auto-pause, or times where you don’t have good GPS (treadmills, indoor track, etc) they are very helpful.

TO access the calibration screen, from the Sensor screen (shown above) tap on the name of the currently paired foot pod sensor.

Note that to true up a foot pod, a calibration factor must be determined. Luckily, You will want to do an initial run with a known distance, ideally a run you do regularly (so it can be using the average stride length on that route as your average), and longer tends to be better than shorter.

Then, to calibrate your foot pod after your run:

  1. Calculate the factor to calibrate by using the formula:   [Distance recorded by GPS] / [Distance measured by Foot Pod] – for example, if you did a 5 mile run using the foot pod, and the foot pod says you went 4.9 miles, the factor would be:  5/4.9 = 1.020
  2. Tap the name of your Foot Pod from the Sensor screen.
  3. Tap Calibration
  4. Enter that calibration factor in the Actual Distance for 1 mile field.
  5. Appreciate the awesomeness that is accuracy!

All of your foot pod workouts will use this calibration factor to assure that your Fitdigits results are as accurate as possible.

Side note – sometimes the foot pod distance is off due to improper setup. For example, if it is not as secure on the shoe and bounces around a lot, it may be prone to be less accurate. Please consult the manufacturers suggestions.
