RECEIVE CHECK / RADIO POWER:
In 2.0.2 (and possibly earlier versions) the PowerCycleC configuration
provides two State interfaces:
interface State as SplitControlState;
interface State as RadioPowerState;
The State enumerator, which should actually be located in a header file and
not the PowerCycleP module, looks like this:
enum {
S_OFF, // off by default
S_TURNING_ON,
S_ON,
S_TURNING_OFF,
};
The RadioPowerState interface can only be S_ON or S_OFF according to the
PowerCycleP code. And the SplitControlState can be any of the 4 states.
So, tap into PowerCycleC's State interfaces and you can query the state of
the radio:
call RadioPowerState.isState(S_ON);
call SplitControlState.getState();
etc...
TRANSMISSIONS:
The DefaultLplC configuration provides a similar interface for the Send side
of things:
interface State as SendState;
Its State enum is in the DefaultLpl.h file:
typedef enum {
S_LPL_NOT_SENDING, // DEFAULT
S_LPL_FIRST_MESSAGE, // 1. Sending the first message
S_LPL_SENDING, // 2. Sending all other messages
S_LPL_CLEAN_UP, // 3. Clean up the transmission
} lpl_sendstate_t;

Subject: [Tinyos-help] checking the radio status when using low
powerlistening?
Hi
is there a quick and concise way to check whether the radio is on/active
when using low power listening? For example, if I wanted to shut the radio
off fully (AMControl.stop()) but only if I was certain LPL was not in the
middle of detecting energy or receiving a packet and had initiated or
completed its own radio turn off action. Something along the lines of
Timer.IsRunning() perhaps?
Regards
Ben
