I want to connect FT232R chip to android phone. I have downloaded FTDI terminal for android from https://play.google.com/store/apps/details?id=com.ftdi.j2xx.hyperterm FTDI program has to startautomaticly when I connect FT232R chip to phone. Sometimes it works fine, but sometimes android does not detects chip. sometimes chip is detected only 1 of 10 times. What could be the reasons?
