Step 3: Turn On the BT-MSPAUDSOURCE Board
Connect the mini-USB cable to the mini-USB port (J4) to apply power to the board. Turn on the board
using the PWR ON/OFF Switch (S2) so that the switch points towards the inside of the board.
NOTE: The board can also be powered from rechargeable batteries (J3), which can be purchased
separately.
Step 4: Automated Pairing and Connection Process
Check the green and red LEDs. These LEDs remain lit when the connection is established and the audio
is being played correspondingly.
NOTE: The BT-MSPAUDSOURCE automatically scans for Bluetooth audio sink devices available in
range. The device lists the Bluetooth audio sink devices in the order they were discovered
and gives priority to the BT-MSPAUDSINK boards. The BT-MSPAUDSOURCE will connect
to the first device available in this list. This procedure can take up to 10 seconds after turning
on the board.
Step 5: Listen to the Audio
Use the capacitive touch buttons to play and pause the audio.
