Function Documentation

void displayReceivedMessages

(

)

Waits for SRDY to go low, indicating a message has arrived. Displays the msg to console.

void displayReceivedMessagesAndFindDevice

(

)

Waits for SRDY to go low, indicating a message has arrived. Displays the msg to console, and find the device's MAC address using ZDO_IEEE_ADDR_REQ. Then, if FIND_NWK_ADDRESS was defined, uses the received MAC address to find the device's short address. The two should match.

Precondition:

callbacks have been enabled with enableCallbacks() - otherwise you will never receive the ZDO_IEEE_ADDR_RSP message.

void pollAndDisplay

(

)

Poll the ZNP for any messages and display them to the console.

Precondition:

SRDY went LOW indicating data is ready

void waitForDeviceState

(

unsigned char

expectedState

)

Blocking wait until a message is received. Exits if received message is a ZDO_STATE_CHANGE_IND and the state matches what we want. Else loops.

Parameters:

expectedState

the deviceState we are expecting - DEV_ZB_COORD etc.
