 One new hardware signal is the ''/RTS'' line indicating readiness of the radio. The other one is an output signal to drive the radio into ''sleep mode'' and back into ''active'' mode.
-The updated state machine works as follows. To keep the battery driven system running as long as possible the radio is in low-power mode most of the time. Only just before sending the µC wakes-up the radio in ''Step2a''. The falling edge of the ''/RTS'' signal indicates the radio readiness which leads into ''Step2''. In ''Step2'' transmission takes place on interrupt basis (started by putchar()). During transmission ''/RTS'' is high. If transmission is over ''/RTS'' goes to low again. If this happens the radio is switched off again. In case transmission couldn’t completed the radio is switched off latest after 200ms. In ''Step3'' we wait for 5s then the board signals the successful transmission with a short blink code (state ''BlinkGood''). An then the cycle begins again. Output PORT1/Bit1 is used for debugging purposes.
