We've taken the popular Circuit Playground Express and made it even better! This is quite funny Ron as I think we have been through all the exact same steps and thus frustrations. And for good reason. Here we will demonstrate software serial with an Arduino UNO and hardware serial with an Arduino MEGA. I'm using the example heart rate monitor from the library adafruit bluefruit nRf5. For most people, theyll be very happy to use the standard Nordic UART RX/TX connection profile. by plc_gremlin Thu Dec 28, 2017 1:52 am, General project help for Adafruit customers. Mouser Electronics Singapore - Electronic Components Distributor. The Bluefruit LE UART Friend makes it easy to add Bluetooth Low Energy connectivity to anything with a hardware or software serial port. It's WiFi half can be used to make Internet of Things devices cable-free or we also love to take advantage of the Raspberry Pi and BeagleBone USB ports to add a low cost, but high-reliability wireless link. It is funny that there is no section on pin i/o for the bluefruit friend. The Remote Procedure Call (RPC) serial code examples could also be used to remotely control the mbed using the Bluetooth module, since the characters in commands wind up coming in on the serial port from the Bluetooth module. A third alternative would be to use the I/O device hardware register pointers to write your own getc() routine to directly read the serial port hardware, but you would need to be careful about using other mbed APIs on the same serial port and not let it setup interrupt buffers for the serial port. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. Check out our tutorial for all of the details that you can dream of!
