Just power it and the 'Friend will bleep out a URL to any nearby devices with the UriBeacon app installed. Turn it into a UriBeacon, the Google standard for Bluetooth LE beacons.Can become a BLE Heart Rate MonitoråÊ(a standard profile for BLE) - you just need to add the pulse-detection circuitry.The Bluefruit can also act like an HID KeyboardåÊ(for devices that support BLE HID).We have aåÊ color picker, quaternion/accelerometer/gyro/magnetometer or location (GPS), and an 8-buttonåÊ control game pad. Using our BluefruitåÊ iOS AppåÊoråÊ Android App, you can quickly get your project prototyped by using your iOS or Android phone/tablet as a controller. Really, way too long to list here!ĭownload our free Android/iOS app and you're ready to rock! You can also use the AT commandsåÊ to query the die temperature, check the battery voltage, and more, check the connection RSSI or MAC address, and tons more. The board is capable of much more than just sending strings over the air! åÊThanks to an easy to learnåÊ AT command set, you have full control over how the device behaves, including the ability to define and manipulate your ownåÊ GATT ServicesåÊand Characteristics, oråÊchange the way that the device advertises itself for other Bluetooth Low Energy devices to see. You can use ouråÊ iOS AppåÊoråÊ Android AppåÊto get started sending data from your Arduino to your phone quickly and painlessly. In this profile, the Bluefruit acts as a data pipe, that can 'transparently' transmit back and forth from your iOS or Android device. ![]() This multi-function module can do quite a lot! For most people, they'll be very happy to use the standard Nordic UART RX/TX profile. You can rearrange any and all the pins if you'd like, by cutting the jumpers underneath, and soldering jumper wires to your desired pins. It connects to your Arduino or other microcontroller using the hardware SPI interface (MISO, MOSI, SCK) plus a chip select line (default D8), interrupt line (default D7) and reset (default D4). ![]() TheåÊBluefruit LE ShieldåÊmakes it easy to add Bluetooth Low Energy connectivity to your Arduino or compatible.åÊ Solder in the included headers and plug right in. So what you really need is the new Adafruit Bluefruit LE Shield for Arduino! Would you like to add powerful and easy-to-use Bluetooth Low Energy to your robot, art or other electronics project? Heck yeah! With BLE now included in modern smart phones and tablets, its fun to add wireless connectivity. Adafruit_BluefruitLE_SPI ble(BLUEFRUIT_SPI_CS, BLUEFRUIT_SPI_IRQ, BLUEFRUIT_SPI_RST) hardware SPI, using SCK/MOSI/MISO hardware SPI pins and then user selected CS/IRQ/RST */ Uncomment this line */Īdafruit_BluefruitLE_UART ble(Serial1, BLUEFRUIT_UART_MODE_PIN) or hardware serial, which does not need the RTS/CTS pins. #ifdef Serial1 // this makes it not complain on compilation if there's no Serial1 Required with UART to slow down data sent to the Bluefruit LE! Please note the long strings of data sent mean the *RTS* pin is MIT license, check LICENSE for more informationĪll text above, and the splash screen below must be included in Please support Adafruit and open-source hardware by purchasing This is an example for our nRF51822 based Bluefruit LE modulesĪdafruit invests time and resources providing this open source code, I have attached the arduino file containing both tabs of code.Ĭode to sense heart rate and send to mit app inventor. ![]() I configured the bluetooth using published code from the adafruit manufacturer. However, I am lost on how to code the heart rate (myBPM) to be sent over bluetooth to the appinventor. I am able to get the sensor to detect heart rate and print it on to the serial monitor on my computer. I want to then send that variable (myBPM) over bluetooth to an app created on MIT appinventor. ![]() I am trying to read in an analog value (myBPM) using the adafruit flora app using pulse sensor.
