Kerimil has created another app for interfacing mobile phones and microcontrollers through Bluetooth. This time it’s a simple phone controlled RGB LED. The Arduino sketch/code can be found in his Arduino Forum post. The Android .apk file can be downloaded from Google docs, as well as a zip file containing the Android source.
Via the contact form.
I used it once. It’s a kludge. It crashes all the time.
Ohh god thx for posting it
I couldn’t get it to crash but then I noticed that the sketch I pasted on arduino forum lacks one line in void setup >
Serial.setTimeout(50);
I must have selected the wrong window when copy pasting – it’s now fixed.
Anyway just to make everything neater I upgraded the app to only send values when they change
I guess this is regular bluetooth, I think 2.1 is the version, correct?
This would be easy with bluetooth 4.0 ;)
It does not support BLE yet.
