Bluetooth
CheckPoint Two
has been tested - successfully - with the following
sensors.
- wahoo (must be 'speed' model not 'cadence')
- xoss (there is only one model, it is selectable between
speed and cadence - select speed)
- cycplus (must be 'speed' model not 'cadence')
If you use other sensors, please provide feedback to the
developer.
Using Bluetooth
- purchase of
a speed sensor is required
- follow setup instructions from the manufacturer of the
sensor
- securely mount the sensor to the hub of the front wheel
- if not waterproof, seal the sensor with duct or
electrical tape
Starting Bluetooth-
- Turn on
bluetooth using iPhone's settings -
Settings...Bluetooth...Push slider to ON
Most bluetooth sensors do not transmit if they have been
stationary for several minutes.
- Roll the front wheel through one revolution to activate
the sensor.
- open the app, make sure Bluetooth is ON in the apps'
setup page
- go to 'GO' tab
The sensor should connect automatically. Special
'Pairing' is not required.
In the app you will get confirmation of the sensor model
number on the bottom of the 'GO' page
If there are several riders nearby with Bluetooth
sensors, you may need to separate from them
- if necessary allow about twenty feet of separation from
other riders.
If the above steps do not get you connected - do the
following
- turn off the app
- turn off bluetooth in iPhone settings.
- activate the sensor (roll your wheel) - sensor will
start blinking
- start the app, make sure bluetooth button is on in app
- go to 'GO' page.
You will receive a system dialog box telling you to turn
on blue tooth, with two choices 'OK' and 'Settings'
Choose 'Settings', iPhone settings will open, turn
bluetooth on, close settings,
return to app - you're good to go
Mileage Accuracy
In some
locations GPS may provide acceptable accuracy in tracking
mileage taveled.
For best accuracy use of a Bluetooth sensor is
recommended.
When using Bluetooth it is important that the wheel
circumference is entered accurately.
Whether using Bluetooth or GPS, rider input can help to
assure that displayed mileage remains accurate.
Whenever the club posts a mileage on a turn, gas stop,
reset, etc. - use the swipe feature to tweak the
displayed mileage to agree with the posted value.
For example - at a gas stop. It can take some 'riding
around' to locate your gas can.
When ready to leave the gas stop, swipe left or right
until displayed mileage is exactly equal to gas stop
mileage.
At resets, free times and gas stops - always take
advantage of the opportunity to tweak mileage to the
exact
mileage shown on the route sheet.
Wheel Circumference
Just as with
an electronic odometer, when using a bluetooth sensor,
the wheel circmference must be known by the
app in order to calculate and display distance travelled.
CheckPoint Two requires user to input wheel
circumference on the setup page - in milimeters
(mm). Measuring
Wheel Circumference
Roll bike
forward until valve stem is perfectly at the bottom of
the wheel. Put a mark on the ground next to valve stem.
Carefully roll the bike forward in a straight line until
the valve stem is again perfectly at the bottom.
Mark the ground again next to the valve stem. Measure the
distance between the two marks as wheel circumference.
If you measured in inches, multiply by 25.4 to obtain
milimeters.
Example 84.75 inches x 25.4 = 2153 mm. Enter this value
on the setup page.
Reset all Data
When you are ready to enter data for a new race, all of
the input data from the previous race can
be deleted easily.
On the setup page - select button at bottom right corner
of screen.
Data .. Reset.
A dialog box will ask if you are sure - select OK.
All reset, free time, speed changes will be deleted.
Also input data from the setup page will be set back to
defaults.
Approaching a Possible Check
Point
At all times
the next possible check point mileage will be displayed
on line two
At all times you should try to keep 'On Time' displayed
on line one
If you are riding on time and within 20 seconds of ideal
time, as you approach a possible you
will obtain a warning - on line one 'Check' and the
mileage of the upcoming theck.
As long as you keep 'On Time' in display, you will never
burn a check.
If the display changes to 'Early' you are at risk of
entering the check hot.
Once the time has arrived to enter the check, the upper
right display will change from
'Check 12.4' to 'Go'.
At the same time you will hear the multi beep signal
indicating time to go.
If you are approaching the check mileage but more than 20
seconds behind perfect time,
you will not receive the yellow check warning, You will
see 'On Time' and the 'Go' indicator.
If you are approaching the check mileage but you are
early,
you will receive the yellow check warning. You will not
get the 'Go' indicator unless you
slow down into the 'on time' range.
If you are approaching the check mileage but you are
late,
you will not receive the yellow check warning. You will
just see the 'Go' indicator
If you are within 20 seconds of ideal time, as you get
very near the check, the display
of 'Chk Time' (third line of dispay) will change to
yellow color. This field shows seconds of key time.
Approaching the check, this field is advancing :40, :41,
.... up to :59, :00.
Reaching :00 is another indicator that it is safe to
enter the check.
Key Time
The setup page
includes a live display of key time. This display should
be set to exactly match
the key time displayed at event sign up. Do not adjust
key time for your row number. The app will
take care of that. Key time on setup page should EXACTLY
match key time dispalyed at sign up.
The app uses your phones system time as the staring point
for key time. If the club is using the
time from a reliable source, including perhaps their cell
phones, you will most likely not need
to make any adjustments to key time. But if setup page
key time does not exactly match the club's
key time - you should make adjustments on the setup page.
It should match within one second.
To adjust key time, press the H button to cycle between H
(hour), M (minutes), S (seconds) and
adjust as necessary.
