Method Detail

policyHasChanged

public void policyHasChanged(IConnectionID conn,
                             RadioPolicy selection)

Description copied from interface: IRadioPolicyManager

Notify the policy manager that a policy has changed

Specified by:

policyHasChanged in interface IRadioPolicyManager

Parameters:

conn - the connection owning the policy that has changed

selection - the required radio state

registerConnection

public void registerConnection(IConnectionID conn)

Description copied from interface: IRadioPolicyManager

Notify the policy manager of a new connection

Specified by:

registerConnection in interface IRadioPolicyManager

Parameters:

conn - the connection being registered

deregisterConnection

public void deregisterConnection(IConnectionID conn)

Description copied from interface: IRadioPolicyManager

Notify the policy manager that a connection has closed

Specified by:

deregisterConnection in interface IRadioPolicyManager

Parameters:

conn - the connection being deregistered

isRadioReceiverOn

public boolean isRadioReceiverOn()

Specified by:

isRadioReceiverOn in interface IRadioPolicyManager

Returns:

true if the radio receiver is currently enabled

setRxOn

public boolean setRxOn(boolean rxState)

Description copied from interface: IRadioPolicyManager

Attempt to set the radio receiver to on or off

Specified by:

setRxOn in interface IRadioPolicyManager

Parameters:

rxState - true for rx on, false for rx off

Returns:

true if the radio receiver is in the requested state after this call

getChannelNumber

public int getChannelNumber()

Description copied from interface: IRadioPolicyManager

Answer the current channel number (between 11 and 26).

Specified by:

getChannelNumber in interface IRadioPolicyManager

Returns:

current channel number

getIEEEAddress

public long getIEEEAddress()

Specified by:

getIEEEAddress in interface IRadioPolicyManager

Returns:

the 64-bit IEEE address of this device

getOutputPower

public int getOutputPower()

Description copied from interface: IRadioPolicyManager

Answer the radio output power in decibels.

Specified by:

getOutputPower in interface IRadioPolicyManager

Returns:

- radio output power

getPanId

public short getPanId()

Description copied from interface: IRadioPolicyManager

Answer the current pan ID.

Specified by:

getPanId in interface IRadioPolicyManager

Returns:

current pan ID

setChannelNumber

public void setChannelNumber(int channel)

Description copied from interface: IRadioPolicyManager

Set the current channel number (between 11 and 26).

Specified by:

setChannelNumber in interface IRadioPolicyManager

Parameters:

channel - - the new channel number

setOutputPower

public void setOutputPower(int power)

Description copied from interface: IRadioPolicyManager

Set the radio output power in decibels (between -32 and +31). NB. The range given is the I802.15.4 standard range. In practice, the CC2420 radio has a range of power settings that do not map precisely to particular decibel levels. In particular, for all channels other than 26, any value from 0 to 31 db will set to radio to maximum power which is 0 db. For channel 26, the maximum power is -3 db, which will be set for all input values from -3 to 31 db. In both cases, setting a lower decibel level may result in reading back a different value, because only 22 CC2420 power levels are available and so some correspond to more than one decibel level.

Specified by:

setOutputPower in interface IRadioPolicyManager

Parameters:

power - - new power setting in decibels.

setPanId

public void setPanId(short pid)

Description copied from interface: IRadioPolicyManager

Set the pan ID (should not be -1 or -2, which are reserved in the I802.15.4 standard).

Specified by:

setPanId in interface IRadioPolicyManager

Parameters:

pid - - the new pan ID

closeBaseStation

public void closeBaseStation()

Description copied from interface: IRadioPolicyManager

Used in the host to close down the base station - a no-op if called on a Spot

Specified by:

closeBaseStation in interface IRadioPolicyManager
