Success!!
After finally getting the ethernet working, I have finished the first steps of learning this new device. I got the BBB working with the HC-05 bluetooth module. For now I’m just talking back and forth through a terminal, and using Python on the BBB end.
This is a pain to get started on, but once it works, it is so much cleaner than with arduino. Since everything is 3.3v, you don’t need any voltage dividers. #beagleboneblack
yeah, it’s actually running basically headless there. I’m connecting via SSH over the ethernet to play with the python code for testing and tweaking, and using a terminal connection to manually send and receive data for testing, but all of that is just for testing and debugging. Commands can easily be executed without it.
You should be able to use all functions pretty easily.
Sure. This post on Hipster Circuits is how I got the serial connection up and running for UART4. http://hipstercircuits.com/enable-serialuarttty-on-beaglebone-black/
the tty04 file goes away each time you restart the BBB, so you have to do the last part of the tutorial each time you restart.
Then it’s really just a matter of using UART4 on pins P9_28 and P9_29 (GPIO_30 and GPIO_31).
It’s pretty straightforward serial communication from there. I used pySerial and Python for communication from the BBB. If you’re at all familiar with the HC05, it shouldn’t be any trouble.
