Firmware-75 Function-118
BIOBEAT3D (118, 76h)
The BioBeat3D function enables output of the BioBeat3D sensor data in both host and stand-alone mode. In host mode the sensor data is output in I2C DATA messages. In stand-alone mode the sensor data is output according to the stand-alone mode settings of the input number that equals the I2C port number. There are the following methods to select, using the FUNCTION command’s method/parameter FP:
BioBeat3D v1.0

Example:
In order to enable the BioBeat3D function to output the heart beats per minute (BPM) and SpO2 percentage measured by a BioBeat3D sensor with I2C device address 87 (default BioBeat3D I2C device address) connected to the 7th I2C port, the following message is sent:
- 240, 125, 0 {DEV}, 8 {FUNCTION}, 6 {yyy = 6}, 87 {device address}, 118 {BioBeat3D function}, 0 {BPM and SpO2 method}, 247 (F0h, 7Dh, 00h, 08h, 06h, 57h, 76h, 00h, F7h)
In host mode raw sensor data will be output immediately in I2C DATA messages. In stand-alone mode a suitable configuration has to be set using the EDIT CONFIG command before any MIDI messages will be output.
Other settings of the BioBeat3D sensor can be effectuated by using I2C commands such as I2C WRITE and I2C READ. See also the datasheet linked from the BioBeat3D v1.0 webpage.
