Bluetooh uart friend !!

Post by jefferyjames »

I am trying to teach my students how to use Bluetooth with an Arduino Uno and cannot control an led with the Bluetooth connect app I keep getting a "No Response to Capability Query" when I go to set a pin I have an LED connected to as an output. I have connected the UART Friend as suggested on your website. My Arduino sketch checks that it compiles correctly. However, as the Bluetooth with Arduino is fairly new to me I am unsure if I have included the correct libraries of even have the sketch correct. Are there sample sketches that I can utilize and what library/libraries do I need to demonstrate how to turn on/off an led using the Bluefruit connect app on my iPhone.

Let's make sure the basics are working OK. Here's the main guide for the UART BLE Friend:

Are you following the wiring here?

and trying to run one of the examples from the library?
