2.9 Command Prompt Feature
The Microchip Bluetooth Audio app provides a
command prompt feature. Any command can be sent
from this command prompt to a connected BM83
device, as illustrated in Figure 26. This feature is used
to test the customized command such as lighting
control, volume control of particular speaker, zone
information extraction and reprogramming, etc.

2.10 Firmware Capabilities/Features
The following features are supported in the
MSPK2v1.x firmware:
LDAC™ CODEC
The SBC and the AAC audio data will pass through the
DSP audio effect and equalizer, but LDAC will bypass
the blocks and go directly to the I
2
S output, as shown
in Figure 27. The user cannot change the EQ during
LDAC streaming. Therefore, LDAC can not be used
with internal CODEC configuration.
Note 1: The BM83 modules mentioned in this
document do not support LDAC function-
ality.
2: The IS2083BM-2L2 SoC supports
decoding for Sony's LDAC codec. How-
ever, a Non-disclosure Agreement (NDA)
is required from Sony. For more informa-
tion, contact a Microchip representative.
