BLExAR vs Arduino Programming Pro

BLExAR turns your iPhone or iPad into a pocket bench instrument for Arduino-class boards over Bluetooth Low Energy. Connect to a board with an HM-10 style UART module (CC2541, AT-09, JDY-08, SH-M08), an nRF52840 MakerBLE board or a Seeed XIAO ESP32-C6, then switch pins, stream sensor values, plot and record them, all without writing an app of your own. BLExAR 3.0 is a complete rewrite that keeps working with the sketches and tutorials written for earlier versions: the same commands, the same pins and the same CSV files. CONTROL • Switch digital pins and set PWM from pin tiles laid out like your board's header • Analog sliders for the A-pins • Board profiles for Arduino Uno, Arduino Nano, MakerBLE (nRF52840), Seeed XIAO ESP32-C6 and the classic 2.7 layout • TX/RX activity lights show every message to and from the board DATA • Live chart of the comma-separated values your board sends, with Run/Hold and 10 s, 1 min and 10 min windows • Readout cards with min, max and standard deviation for each series, plus the incoming stream rate • Record sessions to CSV, optionally with your location on each row, and keep recording in the background • Browse, reopen and share recorded sessions; they also appear in the Files app CONSOLE • Serial terminal to send and receive text, with a hex view and quick command keys PANELS • Build your own control dashboards with buttons, toggles, sliders, a joystick and gauges bound to your board's commands and data columns • Share panels with others as files ALWAYS AT HAND • Live Activity on the Lock Screen and in the Dynamic Island while connected or recording • Control Center controls to toggle a pin without opening the app • Scan list puts UART-ready boards first, ordered by signal strength • Automatic reconnect after a dropped link • Light and dark appearance and Dynamic Type BLExAR is made for makers, students, teachers and engineers.
