Android Question How to make a bluetooth application for arduino project with multiple switches?

[Charlene Tessa Descallar]

Hi,

I am currently working with an arduino project to turn on/off for example multiple LEDs with corresponding switches in the application via bluetooth using asynctreams. My project is based on this https://www.b4x.com/android/forum/threads/hc-05-classic-bluetooth.66677/#content but with multiple switches for multiple LEDs. How can I program each switch in the application in order for the arduino to identify which LEDs to turn on/off

Use B4RSerializator: https://www.b4x.com/android/forum/t...ceive-objects-instead-of-bytes.72404/#content
Send the pin number and the new state. You can send it as an array of two bytes.

Hi Erel,

what if i wrote my arduino program with an arduino.exe software instead of B4R? Also, how can i program my project if it is something for remote control projects like remote control cars, etc.?

So you will need to implement your own protocol.

is there any basic know-hows/steps for me to be able to do so?

Why not use B4R to develop the Arduino program? It will be simpler.
