I am trying to use the Fio V3 to communicate with a serial device using the SparkFun RS232 Shifter - SMD (PRT-00449) connected to a pair of the Fio pins. For simplicity of wiring, I am also trying to power the level shifter using the ground and +5 V from the Fio USB connector.
Unfortunately, I haven't been able to make the it work. Using the SoftwareSerial package, transmitting from the device to the Fio works fine, but transmitting from the Fio to the device does not. I have tried pins 10 and 11 (Fio Rx and Tx) and also pins 10 and 3, with similar results
I have tried the same setup with the SparkFun RedBoard, using pins 10 and 11 (and the Redboard's +5V and ground), and communication works well in both directions.
My question is: Is this something that should work on the Fio?
Thanks
