The I2C port and the temperature sensor

BL600 e-BoBPart 4
Our little wireless communications module has only seven input/output ports, but its I²C port gives it considerable possibilities for extension. We can use it for communication with various components such as temperature sensors, D-A and A-D converters, etc. Here we will use it for exchanging data, the new service Health Thermometer via Bluetooth Low Energy instead of the UART service used in previous installments.
