![]() I then went back to my first app and that had now stopped functioning as well. All went well for about a day and half then this app stopped finding BLE devices. ![]() The next app I developed by downloading the BluefruitLEDcontroller.aia file and then modifying it. My first MIT app I built following the online instructions which included downloading and installing the latest BluetoothLE extension. Para más detalles ver el siguiente enlace: think my problems are associated with updating the BluetoothLE extension but I don’t understand why.Īn explanation of what I did may be of interest: Easy AT command set tunneled over SPI protocol to get up and running quicklyĭatasheet, firmware files, CAD files, and Fritzing object available in the product tutorial Bootloader with support for safe OTA firmware updates 5V-safe inputs (Arduino Uno friendly, etc.) Transport: SPI at up to 4MHz clock speed and so we aren't at the mercy of any third party vendors who may or may not be interested in keeping their code up to date or catering to our customer's needs.īecause we control everything about the product, we add features that are important to our customers, can solve any issues that do come up without begging any 3rd parties, and we can even change Bluetooth SoCs entirely if the need ever arises! We control every line of code that runs on our modules. One of the biggest advantages of the Adafruit Bluefruit LE family is that we wrote all of the firmware running on the devices ourselves from scratch. ![]() There are plenty of BLE modules out there, with varying quality on the HW design as well as the firmware. Just power it and the 'Friend will bleep out a URL to any nearby devices with the UriBeacon app installed.īuilt in over-the-air bootloading capability so we can keep you updated with the hottest new firmware. Use any Android or iOS device to get updates and install them! Turn it into a UriBeacon, the Google standard for Bluetooth LE beacons. The Bluefruit can also act like an HID Keyboard (for devices that support BLE HID)Ĭan become a BLE Heart Rate Monitor (a standard profile for BLE) - you just need to add the pulse-detection circuitry We have a color picker, quaternion/accelerometer/gyro/magnetometer or location (GPS), and an 8-button control game pad. Using our Bluefruit iOS App or 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 commands 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! Thanks to an easy to learn AT command set, you have full control over how the device behaves, including the ability to define and manipulate your own GATT Services and Characteristics, or change the way that the device advertises itself for other Bluetooth Low Energy devices to see. If you like Serial communication more than SPI, we also have a version that can talk UART You can use our iOS App or Android App, or write your own to communicate with the UART service. 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 connection profile. Connect to your Arduino or other microcontroller using the common four-pin SPI interface (MISO, MOSI, SCK and CS) plus a 5th GPIO pin for interrupts (to let the Arduino know when data or a response is ready). With SPI, you don't have to worry about baud rates, flow control, or giving up a hardware UART port. The Bluefruit LE SPI Friend makes it easy to add Bluetooth Low Energy connectivity to anything with 4 or 5 GPIO pins. So what you really need is the new Adafruit Bluefruit LE SPI Friend! 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.
