  • This is a great little WiFi. Needed to INVERT the RS232, but now works like a charm. Using the AdHoc mode, I ran 3.3 volt power, held the AdHoc line HIGH, run the RX,TX to a PIC 12Fxxx and out to my USB/RS232 dongle and in ten minutes, I was sending data and commands from my iPhone. Starting to write an iPhone/Android app to automate the process.

  • RS232 TX from WiFly Ver2.27 is INVERTED
