Using the BLExAR iOS app to control the pins on a BLE Nano Arduino board via Bluetooth Low Energy (BLE). The BLExAR app permits control of the BLE Nano from any of the digital pins 2 - 13, and analog pins 0 - 5. The BLExAR radio buttons instructs the BLE Nano to turn the RGB LEDs on and off. The BLExAR app also allows control of PWM values on the PWM pins (digital pins 3, 5, 6, 9, 10, 11). The PWM control allows users to dim and brighten the LEDs.

More about BLExAR:
BLExAR is an integrated app that uses Bluetooth Low Energy to convert an Arduino board into an iOS-compatible device. BLExAR allows the iOS user to control all digital and analog pins on most Arduino-based boards using just a CC2541 (HM-10, AT-09, JDY-08, SH-M08) Bluetooth board.
Some features include: real-time control of all Arduino pins, data plotting in real time, data logging to a comma-separated file, capturing GPS coordinates of data points, and serial text communication using a terminal window.
The BLExAR app is intended for makers, students, and engineers interested in communicating between their Arduino and smartphone, whether for hobby or professional purposes. The app allow users to interact with their Arduino board, but also receive data from sensors and log precise measurements in time and space with GPS coordinates.
