Sign in to add this video to a playlistIt helped me a lot to understand how I can communicate via USB with my phoneI clicked the github link and downloaded the entire repository, and I found a JAR file under gradle >> wrapper >> gradle-wrapper.JARI got through with no major troubles, and its working perfectlyx Dismiss Join the Stack Overflow Community Stack Overflow is a community of 7.6 million programmers, just like you, helping each otherYou will have to do this for each button.The USB Serial LibrarySetting up a serial connection in Android is quite a hassle because it will require you to manually configure a lot of stuff, so I had been looking at some libraries which do all this automatically
This requires the use of SoftWare serial ad so far I haven't got anybody else's sketches to work!!So I decided to make a very simple example; it works, and here it is: /* Demonstration of sending data to an Android App via BluetoothUsbSerialInterface.UsbReadCallback mCallback = new UsbSerialInterface.UsbReadCallback() { //Defining a Callback which triggers whenever data is readPlease type your message and try againYou still having the issue ? It can be something else not the Id problemhas anyone found a solution?
