9. Once BM83 AT has established a connection
with the sink devices, it remembers the previ-
ously connected devices. Upon power cycle, it
re-establishes the connection with the sink
devices. Now the BM83 can be configured into
Embedded mode by programming the Embed-
ded mode config setting. The BM83 will operate
in Embedded mode where no external host is
required.
3.3 Host mode with PIC32
1. Slide SW300 to the ON position to put the BM83
into Test mode.
2. Connect the BM83 EVB with a mini USB and
toggle the SW200 switch to 5V_USB position.
3. Program the AT firmware, DSP firmware, and
Config Settings (Host mode) from the BM83 AT
package (IS2083 Turnkey v1.x\Software\IS2083
Image\AT v1.y\Host Mode) into BM83 using the
isUpdate tool. Refer to the BM83 Bluetooth
®
Audio Development Board User’s Guide, chap-
ter 5.0 Flash Update for details.
4. Once programming is completed, slide SW300
to position 1 to put the device into Application
mode and change jumpers to Host mode set-
tings. Refer to the BM83 Bluetooth
®
Audio
Development Board User’s Guide, Appendix F
for Host mode jumper settings.
5. Program the PIC32 with PIC32 AT firmware
(IS2083 Turnkey v1.x\Software\PIC32
Image\AT v1.y). Refer to the BM83 Bluetooth
Audio Development Board User's Guide,
Appendix E for details.
6. Press and hold SEL to put the BM83 in Discov-
ery mode. The Blue and Red LEDs will start
flashing alternately to indicate that the BM83 is
in Discovery mode.
7. Put a sink device in Pairing mode and pair it with
the BM83 (keep the sink device in a close prox-
imity to the BM83). Once the sink device is
paired with the BM83, the Blue LED will flash
periodically.
8. To connect with a second device, power off the
Note: To program the MSPK firmware (image1),
DSP (image2), and configuration
(image3), the image num value must be
selected as 3 in the isUpdate Tool.
