Newbie here … sorry if too basic or already answered somewhere, I can not find what I’m looking for. Here is my problem:
I’m trying to connect my BBB to an android device via bluetooth. I’m using a HC-05 device and followed the instructions in here. It works to some extent. Bluetooth connects to the devide and I can send messages to my android device runninga terminal software ( BLUETERM). Problem is that I can not read from the device (which BTW is the sole purpose of the connection …).
I’m doing it pretty basic by now, just some echo hello > /dev/ttyO4 and cat /dev/ttyO4 The first works, the latter doesn´t. All I’m trying to do by now is to make some sort of simple android app that can turn on and off some LED on the BBB. Later will go more complex but what I need now is to set the foundations to my project.
It would be great if there is a tutorial somewhere on how to open a shell over bluetooth from the android device, would be wonderful. I found some on how to do it on rasPi but no luck with BBB
Any advice? any tutorials? any help …??
If I have to be more specific please let me know what you need and I’ll give the informion. I’m running trhe latest armstrong distribution n a BBB rev B.
Thanks for any help!
