Serial Monitor Software

I’m having an issue implementing this on a device that has a hub that has a thermal printer, card reader, and scanner attached to it. I only want to access the scanner, but when I run your demo application it says USB Connected followed by Device not Supported. This happens three times and the app crashes each time when I try to scan. The third time I run the application it works.

I’m assuming it is trying to connect to every device on the hub, is there a way I can make it only connect to the scanner and ignore other devices? I love that you have offered so much useful code. I used it to write my app that reads from a CP210X. This Arduino is wired directly over USB and works with no delays.

I decided to try a 3DR telemetry radio which also uses the CP210X chip, but it doesn’t work so nice. I only see data in my app every 10 seconds or so. I added a 20 ms delay on my Arduino and that is the best but it still seems to be starting and restarting the delivery of data to my fragment. I tried slower baud rates too and it doesn’t matter. I have a MainActivity and a fragment and the Usbservice.

I have a simple method in main that returns the String (msg.obj) as DataString which I initialized as public static String DataString = ” “; My fragment then uses mActivity,getActivity to get the DataString. I can’t understand why the wired CP210X works great but the radio CP210X has so much trouble. Your DroidTerm works fine with the radio.

Should I not make msg.obj a String and wait until it is in my fragment to convert? Thanks for the UsbSerial, its very good job.

I wrote you with a cuestion about how to change the baud rate, I have solved the problem!!! I did according your answer and I am using satandar baud rate (230400); but I added a delay of 100ms after the change of the baud rate. With this I can change the baud rate without lost comunication!!! Thanks very much I have a new cuestion, when I read the serial port only I read 256 bytes, but were sent 1024. Only is posible to read 256 bytes or I am making a mistake?
