emberAfPluginCountersSendRequest#
EmberStatus emberAfPluginCountersSendRequest (EmberNodeId destination, bool clearCounters)
| N/A | destination | the address of the node to send the request to. |
| N/A | clearCounters | whether or not the destination should reset its counters to zero after successfully reporting them back to the requester. Because of technical constraints, counters are always cleared on a network coprocessor, such as the EM260. |
Send an request to the specified destination to send back a report of the non-zero counters.
Returns
EMBER_SUCCESS if the request was successfully submitted for sending. See ::emberSendUnicast() or ::ezspSendUnicast for possible failure statuses.

bool emberAfPluginCountersIsIncomingRequest (EmberApsFrame * apsFrame, EmberNodeId sender)
| N/A | apsFrame | the APS frame passed to the incoming message handler. |
| N/A | sender | the node ID of the sender of the request. |
Call this function at the beginning of the incoming message handler. It returns true if the incoming message was a counter's request and should be ignored by the rest of the incoming message handler.
Returns
true if the message was a counters request and should be ignored by the rest of the incoming message handler.

bool emberAfPluginCountersIsIncomingResponse (EmberApsFrame * apsFrame)
| N/A | apsFrame | the APS frame passed to the incoming message handler. |
Call this function within the incoming message handler to determine if the message is a counter's response. If so, it is up to the application to decode the payload whose format is described above.
Returns
true if the message is a counters response.
112 of file app/framework/plugin/counters/counters-ota.hemberAfPluginCountersIsOutgoingResponse#
bool emberAfPluginCountersIsOutgoingResponse (EmberApsFrame * apsFrame, EmberStatus status, return)
| N/A | apsFrame | the APS frame passed to the message sent handler. |
| N/A | status | the status passed to the message sent handler. |
| N/A | return | true if the message was a counters response and should be ignored by the rest of the message sent handler. |
Call this function at the beginning of the message sent handler. It returns true if the message was a counters response and should be ignored by the rest of the handler.

MAX_PAYLOAD_LENGTH#
#define MAX_PAYLOAD_LENGTHValue:
48
To ensure the counters response does not exceed the maximum payload length, they are divided into separate messages if necessary. The maximum length of 48 leaves sufficient room for headers, all security modes, and source routing subframes if present. It should not be necessary to change this value, but if you do, make sure you understand the process.
