test report : NXP LPC1769(thanks to mark)
When you connect a CDC-ACM device to Android, please select Menu -> Open Device.
If you have checked operation, please send me message.

- FT230X

FAQ
Q: Why my phone/tablet(Android 3.1 or upper) is incompatible?
A: Maybe, your phone/tablet does not have a USB Host API feature.

Q: But my phone/tablet supports a USB thumb drive, USB mouse and USB keyboard.
A: It's not a USB Host API. It's a Linux USB Host. Please check to see if your phone/tablet have a USB Host API.

Q: Can I get binary or source code?
A: Yes, It's open source. Please check my github page.

Q: How much max output current is?
A: smartphone type : 150 - 180mA(Galaxy Nexus, Galaxy S2)
tablet type : 400mA - 500mA? (ICONIA A500, Nexus 7)

    I was looking for an Android app to monitor my wireless arduinos (panstamps) activities. I tried a few, and this one is the best of the pack : the ability to send the buffer by email is very nice, and its ability to start automatically when connecting the USB device is very good as well. The only annoying fact is that the buffer is limited to about 5kBytes, and there is no way to increase it. Thi

    Plugged in to my Polaroid Tablet. Checked coms by shorting pin 2 and 3 and it certainly only returned the coms when there was a short. Would be nice to have more then just ASCII strings. Binary Decimal hexadecimal would be nice too as well as alternative ways to view the data received for us electronics tinkerers.

    Works fine with FTDI CHIPI-X usb2rs232 interface. Only an issue: terminal does not recognise ANSI escape sequences, such as clear display or move cursor position (sequences starting with {ESC}[ are displayed: for example █[2J instead of executing the command and clearing the screen)

    Works with FRDM-KL25Z with mbed program. Only seems to work up to 9600 baud though. Only app that appeared to work! Would love to have this work faster!
