Section 9.5 Method 4 - Logging Data on a Cell Phone using Bluetooth (CPB Only)

As mentioned in the introduction it’s possible to have the Circuit Playground send data wirelessly to a cell phone using Bluetooth provided you have Bluetooth setup and a smart phone with the Adafruit Connect App. Bluetooth is explained in detail in its own chapter (See Chapter 10). Method 4 is a valid form of logging data it just requires a cell phone to be powered the entire time and it must be within 30 feet of the Circuit Playground at all times. This also only works on the CPB since the CPX does not have a Bluetooth transmitter.
