What's New in BLExAR

3.0

October 10, 2026

BLExAR 3.0 is a complete rewrite for iOS 17 and later. • Workbench design: a bench-instrument look with pin LEDs, TX/RX activity lights, light and dark appearance and Dynamic Type • Panels: build your own dashboards with buttons, toggles, sliders, a joystick and gauges, and share them as files • Faster live plotting with Run/Hold, time windows and min, max and σ readouts for each series • Recording to CSV with optional location, background recording, and a Sessions library that also appears in the Files app • Live Activity and Dynamic Island while connected or recording, plus Control Center controls for pins • Board profiles for Arduino Uno, Nano, MakerBLE (nRF52840) and Seeed XIAO ESP32-C6 • Scan list puts UART-ready boards first, ordered by signal strength • Automatic reconnect after a dropped link • Fully compatible with your existing sketches, commands and CSV files from BLExAR 2.7

I-phone control for Arduino works easily

Of the many ble applications I have tried, this one is the clear winner: It works easily, had good web support and allows to plot sensor data and save as csv while also allowing to control the boards inputs. Used Hm10 and uno but needed to fiddle a bit ti understand some basics of serial communication. Could do with one more basic example.

Outstanding App

Great app for using BLE with an Arduino. Good function set allowing direct control of I/O channels, messaging back and forth through a console, and the ability to download data from the arduino, plot it, and email it as a text file. Great customer support!

Worked for one day

It opens but crashes when I try to do anything with it. $4 wasted.

Don’t buy

No custom functionality. Everything that’s built into the app works. However, so does every other free app on the market. Don’t waste your money like I did.
