The BM83 module supports following modes of
operation in Multi-Speaker solution:
• Embedded mode
• Host mode
2.2.1 EMBEDDED MODE DEMO SETUP
1. Slide SW300 to the ON position to put BM83 into
Test mode.
2. Connect the BM83 EVB with a mini USB and
toggle SW200 switch to the 5V_USB position.
3. Program the MSPK firmware, DSP firmware,
and Config settings (Embedded mode) from the
BM83 MSPK2v1.x package
(IS2083 Turnkey v1.x\Software\IS2083
Image\MSPK2v1.y\SPP\Embedded Mode) into
the BM83 using isUpdate tool. Refer to BM83
Bluetooth
®
Audio Development Board User’s
Guide, chapter 5. Flash Update for details.
4. Once programming is completed, slide SW300
to position 1 to put device into Application mode.
Refer to Table 2 for Embedded mode button
functionality. By default, BM83 EVB is preconfig-
ured with Embedded mode settings.
5. Repeat step 1 to step 4 with all other EVBs.
2.2.2 HOST MODE DEMO SETUP
1. Follow steps 1 to step 2 from Section 2.2.1
