I try to understand if the Mbot works with a bluetooth 4.0 service ? I saw services and characteristics and If I look at the source code of the android application, i see a BLE class with what I supose is the instructions to pass to mBot…
For example for RBG, i saw an instruction of kind rgbrun(port6,slot1,-15454) the last number is corresponding to R<<8+G<<16+B<<24
But If I pass this intruction (convert via an encoding) nothing appens… I send the data to service with UUID 0000ffe1-0000-1000-8000-00805f9b34fb (as I see in the android application) and I send the data to the characteristic with UUID 0000ffe3-0000-1000-8000-00805f9b34fb because it the only characteristic that is in write mode.
What do I miss ? Am i sending wrong message ? Do I have to format it with a special method ? Is the service working ?
