The latter is based on BlueNRG-1, very low power Bluetooth low energy single mode
system-on-chip embedding a high performance, ultra-low power 32-bit Cortex-M0,
with 160 KB of Flash memory and 24 KB of RAM.
The software package includes the entire Bluetooth
®
low energy stack and protocols,
compliant with the STSW-BLUENRG1-DK.
It also contains a board support package that offers a complete set of APIs for digital
MEMS microphone, 3-axis accelerometer and gyroscope, as well as button and LED
management.
The BlueVoiceADPCM binary library, available as middleware, provides a vendor
specific BLE profile for voice streaming and all the APIs needed for audio
compression using the ITU-T G.726 ADPCM standard, packetization and streaming
over BLE.
The STSW-BLUEMIC-1 allows an STEVAL-BLUEMIC-1 evaluation board to act as a
peripheral in a point-to-point connection with a mobile device running ST BlueMS
app, available for Android™ and iOS™. In this configuration, the evaluation board
streams the audio acquired from the on-board digital MEMS microphone
(MP34DT05-A or MP34DT04-C1) or motion data acquired from the 3-axis
accelerometer and gyroscope (LSM6DSL).
