Brotech Electronics Mini Midi Se and Mega Midi Sequencer User Manual 2017-08-13
Miscellaneous
Bluetooth
The standard Bluetooth RF range is at least 10M, or 30 feet. When changing directories or when first powering
on a lot of information needs to be sent from the mMS+/MMS hardware to the tablet. The tablet must be in range
and the signal communication strong for this to work reliably. So at an extreme range, or in an electrically noisy
environment, there may be some interference that would prevent the smooth communication between mMS+/MMS
and tablet. The user is encouraged to be within clear site range of the mMS+/MMS custom hardware when first
running the App or when changing directories.
When connecting the tablet to Bluetooth, MEGAMIDI or M should appear as one of the recognized
devices. If the tablet has in some way been reset or Bluetooth devices has somehow been lost, go to the wireless
configuration screen on the tablet, and search for new Bluetooth devices. With the MMS on, it should find device
MEGAMIDI, or M for the mMS+. Select this device and it will ask for a pass key – the key is located on
the serial tag of the mMS+/MMS.
