This App is aimed at all “Makers” alike, to graph analog sensor data from an Arduino or similar connected to a bluetooth low energy device…

Initially it only supported the following Bluetooth Low Energy devices in our database:

- RFDuino
- RFD22301
- RFD22302
- Bluegiga BLE112-A
- Bluegiga BLE112 Adapter board
- (Untested) RedBearLabs Arduino shield.

The app graphs analog data being sent from the Arduino-BLE device in near-real-time!
It supports one sensor at the time, however Im working on allowing more than one analog signal at a time.

Note: BLE Device must be ON and broadcasting an output signal...
Note2: For a sample program check the website at www.instasgraph.com

- Press scan to scan for devices: It will show you the bluetooth low energy devices available.
- Select the device you wish to inspect: a new list will be populated with the characteristics of that specific device
- If device has a reading characteristic and you know which one it is, select it. Otherwise select any of them and if it does not conform to a reading characteristic, it will return you to the list of characteristics.
- Once a connection is established press the sine to start acquisition: it will start graphing values from your connected device.
- To stop graphing, simply press the sine once more to stop and the App will stop graphing.

If you have a device that isnt supported, e-mail me with your UUIDs at [email protected] and I will add your device to the App as soon as possible!

I am continuously updating the App and adding new features so check back often!
