I am having trouble getting my leaf botanicals kit to communicate. The red light flashes 4 times when pressing the test button. Every couple of seconds the green light flashes but often the red light just stays dark. I purchased the spark fun ftdi cable and have connected it so that black is on gnd and the three pin connector is connected to vin and the center pin. When the arduino program is running I watch the communications via the program and nothing but garbage is being displayed.
Any ideas in troubleshooting this would be greatly appreciated.
