About
This Bluetooth Test Tool is an easy tool to use for developing software and hardware using Bluetooth Low Energy peripherals.
One can easily set the UUID of the BLE device, the UUID's of the RX and TX peripheral services and (optionally) auto connect to the device. If the peripheral successfully connects, a textfield shows and you can now send messages from the iOS device to the BLE devices' UART and vice versa.
On the settings page one can change the UUID values. The app will remember them but only store them on your device (locally).
We use it for testing our Arduino-like applications.

What's New in Bluetooth Test Tool
1.0.1
October 30, 2016
This app has been updated by Apple to display the Apple Watch app icon. Minor update: - Fixed a small layout glitch for iPod Touch. - Fix that prevents a crash when receiving 'illegal' content (e.g. in case of a wrong baudrate on peripheral side). Now just says: "Received illegal chars". - Now shows ASCII char if readable otherwise the (raw) byte value - Added hints when UUID / RX / TX fields in Settings are empty.
