If, for some reason, you cannot get your device to connect to ezRoom even though you had previously been able to stream audio, it
is easy to “re-pair” the device to ezRoom. Simply go to your device settings and select the ezRoom, then “Forget” the device (may
be a right-click, or another button to access this ability). You may then follow the quick steps above for pairing a device.
To clear all paired devices from ezRoom, press the Bluetooth button once to enter pairing mode (pairing tone will sound), then
press again and hold until you hear the reset tone. Note that you will need to go to each device and “forget” the ezRoom, then
pair it again.
FAQs
Q: Do I still need cables to use Lesson Capture?
A: Yes, you still need at least the USB cable (for tower settings,
and voice command start and stop of recording) and the audio
out from the ezRoom to the computer.
Q: Can I upgrade an existing ezRoom?
A: Yes, the module can be installed in any ezRoom in the field
and requires no firmware updates.
Q: What is the multipoint feature of the ezRoom Bluetooth
Audio Receiver?
A: Multipoint is a feature of Bluetooth where two devices can
be connected at once, making it easy for the teacher to switch
between, say, a phone and the computer without disconnecting
each device when she wants to play audio from the other (Only
one device can stream at a time, however.)
Q: When I play video and audio at the same time from my
computer, the audio seems a little out of sync with the
video. Why?
A: The latency of the Bluetooth signal depends on many fac-
tors, including the codecs used by the Bluetooth transmitter and
receiver, the distance between them, other
wireless interference, etc. ezRoom supports the FastStream codec,
which is a low latency codec for maintaining good audio-video sync.
However, if the transmitting device does not support this codec the
audio may look out of sync. Test your environment for acceptability.
You can also try a transmitter that supports the FastStream codec,
such as the Avantree Prima III (available on Amazon).
Q: As a teacher, I allowed a student to pair to the ezRoom
but I don’t want them to play audio whenever they want.
How can I control this?
A: Once a student pairs with the ezRoom and their device they
can connect to ezRoom anytime as long as there are not already
two devices connected. To break the pair, you must either
“Forget the device” in the student’s device Bluetooth settings,
or, as a brute force method, you can clear the pairing list on the
ezRoom. Keep in mind that clearing the pairing list means that
you will need to pair all your devices again. To clear the pairing
list, press the ezRoom Bluetooth button once to put it in pairing
mode (blue button flashing), then press again and hold to reset
while in pairing mode.
