Android Question felUsbSerial library - dataAvailable problem

[carycai]

please see the attach picture.

I add a timer into the demo code,send string "test" every 1 second.And receive string was splited into two lines:"t" and "est". (ps: I link the serial pin 2 & 3 with wire,so it can write and read by itself.)
Why? Is there anything wrong?
Please help me.

Why? Is there anything wrong?

No. This is how network communication works. You should expect messages to be split.

You can use felAsyncStreamsText module to take care of correctly building the message: https://www.b4x.com/android/forum/threads/usb-to-serial-log-string.67231/#post-425804
Each message should end with an end of line character(s).
