BT Audio Module User Guide Class 1 Bluetooth Audio Module www.kcwirefree.com Version December 19, 2014 Page 1 Description The BT AUDIO‐5112 Class 1 Bluetooth Hi Power Audio Module is a highly tuned and completely integrated wireless audio transceiver subsystem ready for installation in audio devices. The BT AUDIO‐5112 is a pre‐engineered subsystem integrating a wireless radio, digital audio system, and programmed firmware profiles that define features, c onfigurations, and user interface. All firmware offered by KC Wirefree can be customized for OEM clients. In many cases a few changes can produce great value by differentiating and improving your product. Firmware can be updated via USB. kcAudioGateway Firmware Edition The kcAudioGateway firmware is a transmitter system, offering A2DP source profile or AGHFP gateway profile (default), but not both simultaneously. A2DP mode provides stereo transmission to Headset/Speaker devices. Stereo audio is sampled from the MIC_L+, MIC_L‐, MIC_R+, and MIC_R‐ pins at 44.1kHz, and will automatically transmit to a Headset device. AGHF P mode (default) provides two‐way voice communications, sampled at 8kHz, to a standard Bluetooth cell phone headset. Additionally, the Headset Voice Command prompt will toggle a PTT pin on kcAudioGateway, which enables standard Bluetooth cell phone headsets to provide a PTT function. Please refer to our kcAudioGateway User Guide for det ails. kcAudioHeadset Firmware Edition The kcAudioHeadset firmware is a receiver system, offering A2DP sink profile, and HFP profile. It can receive an A2DP wireless stereo signal, decompress, and convert to analog audio available on the SPK_L+, SPK_L ‐, SPK_R+, and SPK_R‐ pins. Additionally, it can “answer” phone calls, which will pause any A2DP stream, and sw itch modes, now providing two way mono communication channel. Please refer to our kcAudioHeadset User Guide for details.

PIO inputs are debounced to 20ms. Several PIO pins are assigned functions in default versions of firmware. Custom programmed functions are available. Inputs can be configured for weak pull‐up, weak pull‐do wn, strong pull‐up, strong pull‐down. Voltage input tolerance and output level is directly related to the VDD level. Specific functions are enabled on designated PIO pins depending on firmware version. Please refer to the specific firmware Audio User Guides for complete information regarding PIO features and assignments. LED Pins [10‐11 ] Two open‐drain LED output pins are available. The LED's need a positive 3.3V (maximum) supply, and a current limiting resistor. UART Pins [12‐15] The UART is compatible with the 16450 industry standard. Upcoming kcAudio firmware will implement an AT Command set for configuration and operation. 3V3 _OUT Pin [16] The module has several onboard regulators. The onboard 3V3 regulator supplies the PIO, PCM, SPI, UART, and USB Pins. The class 2 module has up to 100mA available from this pin. The class 1 module also uses the onboard 3V3 regulator to supply the RF Power Amp, and ha s less than 30mA available from this pin. GND Pin [17] VSS ground plane. RESET Pin [18] The module will reset when pulled LOW >5ms. VDD Pin [19] Minimum VDD is 2.9V. Supplies several onboard regulators, and is also the designated Battery P terminal if powering directly from a Lithium Io n battery. The VDD pin may receive a recharge current supply whe…
