NFR24L01 bluetooth module and SPI
May 7, 2012
I am working on my first robot. Ibased it on an ArduinoMega128 and can make it drive a pre-programmed pattern. I now want to control it via bluetooth from my android phone. For this I was given a small BT module yesterday. It is based on the NFR24L01 chip, and contains no serial interface, but rather the default SPI that the chip communicates with. I know the Arduino has an SPI interface on leg 50-53. However, away from connecting, I have no idea on how to begin.
I know I need to add the #include spi.h to my Arduino sketch.
When i connect power (3.3V) to the BT module I cannot find it with my phone (if I search for BT devices).
My documentation is mostly in Chinese, which I do not read that well.
Anybody has experience with this?
And yeah, I'm a beginner.
