## What is Bluefruit Connect?

Wirelessly connect your iOS device to Adafruit Bluefruit LE modules for control & communication with your projects.

Features:
• Send iOS sensor & GPS data wirelessly over Bluetooth LE (Continued use of GPS running in the background can dramatically decrease battery life)
• Control Pad for simple directional control of your projects 
• Control Arduino Digital, Analog, & PWM pin input & output
• Send & receive messages via UART monitor in Hex or ASCII format
• Send & receive messages via CircuitPython REPL
• Control NeoPixels individually with an interactive color picker
• Scan & list nearby Bluetooth LE peripherals with RSSI and Advertisement data
• Connect & List peripheral Services & Characteristics in Info mode
• Serial Plotter to plot numeric data graphically
• Multiple simultaneous connections (UART and Serial Plotter only)
• Send Images via UART
• Update your Bluefruit device to the latest firmware version from within the app
• Use Apple Watch to control Bluefruit with Color Picker & Control Pad

### 5/5 — Mad good

*2022-01-24*

Fire, shoutout p4 Robotics

### 4/5 — Uart issue

*2021-07-27*

The uart interface ignores carriage returns and line feeds sent to the phone, please fix!

### 5/5 — Makes BLE easy

*2019-11-15*

I bought the Adafruit Feather 32u4 Bluefruit LE and by downloading their example code and doing a little reading, with this app you can be sending data back and forth from your iOS device to the bluefruit in no time. I also really like the option to plot the data being sent from the bluefruit. I can't imagine trying to make this app myself mainly because I don't own a Mac but being able to just download this app has made my life so much easer. Great app.

### 5/5 — Adafriut Bluefruit LE Connect app

*2019-10-13*

A very useful app to test the various capabilities of Bluefruit Le Friend products from Adafruit.
Remember to unpair your IOS device from the Bluefruit device before running this app. This app sets up its own pairing with an IOS device, and cannot do so if IOS already has pared.

### 5/5 — Just what I needed

*2018-01-10*

I mainly got this for the resistor codes but I have no doubt I'll put the other tools to use too. It's a nice little app and I'm happy to support Adafruit software!

### 1/5 — Errors on errors

*2017-04-24*

Trying to use this app with our bluefruit receiver as part of a senior project in engineering... version 3.0.3 says it fixed I/O capabilities query, yet I still get that error.  Would be a very good app if it wasn't for getting errors every time.

### 5/5 — Cool app. Latest update is excellent.

*2016-10-05*

This is such a great app. I have an awesome project i made to take to sporting events. It's sweet. But... It is SO hard to pair in a crowded environment. Everyone and their dog has at least one BLE device on them now (anyone reading this will for sure). Their is no filter or way to sort devices to find the adafruit one. This would be a very welcome addition. Filter by name, UART only, sort, something.

Update: they added filtering and it is awesome!  Much appreciated, easy 5 star rating now.

### 2/5 — Problem!!!!

*2016-06-10*

The new 2.0 version has a flaw when sending intensity string to ble device. Previous command was #FFF (RGB intensity) now red and green intensity works normal but blue intensity is only 30% brightness or off entirely! How can I get previous good working version!!! Btw software version changes should have a "revert back" button so when issue like this occur, users can get the last working version!!
Please fix!!

### 3/5 — One flaw

*2016-05-24*

Overall a great application, however you cannot lock the application in landscape mode when using the controller, and when using the iPad in landscape mode the annoying connection window is always in the way. This makes it hard for me to design a controller to work with the quadcopter I'm creating.

### 5/5 — Found my Fitbit

*2016-03-29*

I love this app it helped me find my Fitbit after my son stole it while it was charging. Tore apart the whole house looking finally downloaded this app and found it in minutes!
