The discover new devices doesn't seem to find any devices. My phone bluetooth app shows multiple devices.

I'm getting an error while pairing. the error message is as follows:

read failed, socket might closed or timeout

can i connect two devices without pairing?

Hi, I am a graphic designer, I want to help others in graphic design.

After I reviewed your project, you have no logo on this project. Therefore I want to contribute to this project by creating a new logo / icon. what do you think?

The app loses connection when changing orientation, when the phone is turned with the hand towards the landscape. How to fix this?

so i am trying to connect to a tablet, i hope that works
i know this code is for microcontrollers

but whenever i try to connect the app keeps crashing and gives me this error

Hi, i've detected if i turn on and turn off very quickly, it stucks, so i have to reset the arduino to work well again. I do not know if it is limited by the baud rate or whatever.

My scenario: i'm testing sending/receiving a String (3 chars) with a timer task, sending from Android with a 100ms period. So, Arduino receive it correctly, on, off, on, off... but after some executions, arduino stucks, i think that the bluetooth.available() condition change its states.

I've tried with a delay(5); after each on/off, improving the test, but i get stuck again after some seconds working rightly.

I've tried to thange the baud rate from my initial 9600 to some other, but it fails, i can not get it work if i change the baud rate.

bluetooth.begin(19200); //or some other standard speed rate, does not work anymore

Any ideas? Thx!!

Hi, i'm running your code, Android and Arduino both, my problem is that i can not pair my HC-06 device. However, the system bluetooth of myh phone can discover the HC-06 .... What's wrong? I see that "Discovery started" but the Broadcast Receiver never gets the connection.

I have no crashes, all is running right.

Hello, I will like to contribute to your project, I saw that there are some missing documentation such as About Us, and FAQs, I will like to do them for your project.

I got connection failed error when i try to connect any device even if paired or not paired. How can i solve this problem?
