This program is a successful connection test between mBed and the watch EZ430 Chronos Development Tool from texas Instruments. The radio dongle that comes with the watch emulates a usb serial port when connected to a PC. I connected it to the mBed usb port configures as host ( two 15 K ohms resistors from D+,D- to gnd) and based the development on the USBHostSerial HelloWorld program. The mBed leds are activated based on the button received from the watch : led2 goes on when the "*" button is pressed , led3 when the "#" button is pressed and led4 when the "up"button is pressed . In order to function , you have to select the "ppt control" mode on the chronos watch and after that , start the transmission pressing the "down" button on the watch.
