I have a small question about the i2c bus of the Wiced Sense.
The chip of the Wiced Sense is BCM20737S. Is the i2c bus shared between external sensors and the internal eeprom?
Another question, why an i2c extender chip is required for the external sensors?
The WICED Sense does indeed use the SIP module and leverages the I2C bus on the module for the sensors (using I2C addressing I believe).
The I2C expander/buffer is not required per this thread: Purpose of buffer in WICED Sense
