The URL to the iTunes for BlueNRG is http://itunes.apple.com/app/bluenrg/id705873549?uo=5 The URL to the GooglePlay is https://play.google.com/store/apps/details?id=com.st.bluenrg The source code of the "BlueNRG" app, both for iOS and Android, is freely downloadable from the developer website at http://software.g-maps.it/ NO SUPPORT WILL BE PROVIDED TO YOU BY STMICROELECTRONICS FOR ANY OF THE ANDROID .apk FILES INCLUDED IN OR REFERENCED BY THIS PACKAGE. The board will act as Server-Peripheral. After establishing the connection: - by pressing the USER button on the board, the cube showed by the app on the smartphone in the MOTION tab will rotate on the three axes (x,y,z). - in the ENVIRONMENT tab of the app the temperature, pressure and humidity fake values sent by the STM32 Nucleo to the smartphone are shown. - in the OTHER tab of the app the RSSI value is shown. For testing this sample application, a smartphone (acting as Central device) with the "BlueNRG" app running is needed. This application uses the STM32 Cube Low Level low power optimizations along with the DMA module for offloading the MCU. Current consumption could be monitored through an amperemeter connected to JP6. This application shows also how to add new GATT services and characteristics. Setting the NEW_SERVICES define to 1 (in $PATH_TO_THIS_APPLICATION\Inc\sensor_service.h), two new services are enabled: - the Time Server service, which has two characteristics - seconds, a read only characteristic which exposes the number of seconds passed since system boot - minutes, a characteristic which exposes the number of minutes passed since system boot. This characteristic can be read by GATT server, and a “notify” event is generated for this characteristic at one minute intervals. - the LED service, which can be used to control the state of LED2 present on the STM32 Nucleo board. This service has a writable “LED button characteristic”, which controls the state of LED2. When the GATT client application modifies the value of this characteristic, LED2 is toggled. Hence the application advertises its services and characteristics to the listening client devices while waiting for a connection to be made. After the connection is created by the central device, data is periodically updated. In this example, when the NEW_SERVICES is set to 1, the STM32 Nucleo board acts as GATT server (and as a Peripheral device) and the PC as a GATT client (and as a Central device). The BlueNRG GUI is needed. The BlueNRG GUI installer is provided in the STSW-BLUENRG-DK package available at http://www.st.com The BlueNRG GUI can be used to initialize and configure the BlueNRG USB dongle properly so that it can be used to test the BLE application running on the STM32 Nucleo board equipped with a BlueNRG expansion board. The PC connected to the BlueNRG USB dongle will be configured as “GAP central device”, and the STM32 Nucleo board equipped with a BlueNRG expansion board is “GAP peripheral device”. Once the BlueNRG USB dongle is configured correctly, it can be used to scan remote devices and send the ACI commands. If you don't have the USB dongle, as an alternative you can use a STM32 Nucleo board + X-NUCLEO-IDB04A1/X-NUCLEO-IDB05A1 with the Virtual_COM_Port application included in this package. ------------------ | PC with | | BlueNRG GUI | | running | ------------------ / --------------- / / --------------- / /---------->/ --------- /<------\ USB Mini-B to A Cable / In USB ------------------ \ powering the board / port \ -------------- ----------------------- | BlueNRG |-- | STM32 Nucleo + | | USB Dongle |-- | X-NUCLEO-IDB04A1 | -------------- | or X-NUCLEO-IDB05A1 | ----------------------- The communication is done using a vendor specific profile. @par Hardware and Software environment - This example runs on STM32 Nucleo devices with BlueNRG STM32 expansion board (X-NUCLEO-IDB04A1 or X-NUCLEO-IDB05A1) - This example has been tested with STMicroelectronics: - NUCLEO-L053R8 RevC board - NUCLEO-F401RE RevC board - NUCLEO-L476RG RevC board and can be easily tailored to any other supported device and development board. This example runs also on the NUCLEO-F411RE RevC board, even if the chip could be not exploited at its best since the projects are configured for the NUCLEO-F401RE target board. @par How to use it? In order to make the program work, you must do the following: - WARNING: before opening the project with any toolchain be sure your folder installation path is not too in-depth since the toolchain may report errors after building. - Open IAR toolchain (this firmware has been successfully tested with Embedded Workbench V7.40.3). Alternatively you can use the Keil uVision tool
