jzacaroli 1:7fff8f0dce62 1 /* Simpler prog based on the serial passthrough code to enable a command line driven test of esp8266
jzacaroli 1:7fff8f0dce62 2 * wifi modules.
jzacaroli 1:7fff8f0dce62 3 * NB this uses the mbed sleep() command to form a low power system but on some MCUs this is a problem
jzacaroli 1:7fff8f0dce62 4 * this works fine on an lpc1768 but not as yet on the KL25Z
