Bluetooth
Why can’t I pair my smartphone with
the PINPad?
There could be various reasons for why your smartphone
is unable to pair with the PINPad. Below are some
common reasons and their resolution:
1. Is your smartphone’s Bluetooth is turned on?
You should see the
®
symbol at the top of your
smartphone screen. If you don’t, go into the
settings to enable it.
2. Is your smartphone in discoverable mode?
In order to pair Bluetooth you have to make your
smartphone visible or discoverable to the PINPad.
Once the devices discover one another, the
PINPad will display a numeric code that you must
confirm or enter on your smartphone. After you
do this, the smartphone and PINPad are paired.
Note: Your smartphone only stays in discoverable
mode for a few minutes. If you take too
long you will need to re-enter discoverable
mode.
3. Delete the PINPad from your smartphone
and rediscover it.
If you have paired your smartphone with the
PINPad initially and are now having problems
reconnecting them, remove or forget the PINPad
on your smartphone and re-add it.
Go to your
Bluetooth screen on your
smartphone and either forget the device or
remove it from the list of connected devices.
4. Restart the PINPad and smartphone.
Resetting the devices sometimes resolves the
issue.
5. Is the PINPad and your smartphone close to
one another when trying to pair them?
Ensure that both your smartphone and the
PINPad are near one another when attempting to
pair them. Side-by-side is ideal.
What can interfere with Bluetooth
connectivity?
The biggest issue is that the frequency range (2.4GHz)
used by
Bluetooth is shared by other equipment and can
be blocked by certain materials. There are steps that you
can take that will minimize
Bluetooth connectivity issues.
They are:
1. Distance between the devices
Ensure that you keep your smartphone and
PINPad in the same room if possible. Obstacles
like walls, ceilings/floors or furniture may block or
weaken the
Bluetooth signal.
2. Signal interference
Bluetooth
uses the 2.4GHz frequency range
which is shared by other devices such as:
»
Microwaves
» Wi-Fi devices (routers, VoIP phones,
wireless cameras)
»
Fluorescent office lighting
»
Some cordless phones and baby
monitors
To avoid connectivity and data issues, avoid
going near these devices when using the TD
Mobile POS solution. Of course, you can’t always
avoid sources of interference such as Wi-Fi or
fluorescent lighting.
To accommodate this,
Bluetooth
is able to adapt
to some interference from multiple sources
depending on its strength. But, if you encounter
too many sources of interference at once, your
devices may not be able to adapt and they could
lose connectivity.
3. Your body
You body doesn’t generate a frequency that
interferes with
Bluetooth , but it can actually
block Bluetooth signals. For example, if you carry
your smartphone in your back pocket and the
PINPad in your chest pocket, you may cause the
Bluetooth connection between the two devices
to drop.
