4. Device B should transmit test link packets.
5. When device B completes transmitting the test link packets, it sends the following data packet
to device A's Test Link Result Cluster (0x0094) on endpoint (0xE6).

Example
Suppose that you want to test the link between device A (SH/SL = 0x0013A200 40521234) and device
B (SH/SL=0x0013A 200 4052ABCD) by transmitting 1000 40-byte packets:
Send the following API packet to the serial interface of device A.
In the following example packet, whitespace marks fields, bold text is the payload portion of the
packet:

Description
The address the device uses to test its link. For this example, use the
device A address.
The size of the test packet. Use the NP command to query the
maximum payload size for the device.
The number of packets to send. This must be a number between 1 and
4000.
Field name Description
Destination The address the device used to test its link.
address
Payload size The size of the test packet device A sent to test the link.
Iterations The number of packets that device A sent.
Success The number of packets that were successfully
acknowledged.
Retries The number of MAC retries used to transfer all the packets.
Result 0x00 - the command was successful.
0x03 - invalid parameter used.
RR The maximum number of MAC retries allowed.
maxRSSI The strongest RSSI reading observed during the test.
minRSSI The weakest RSSI reading observed during the test.
avgRSSI The average RSSI reading observed during the test.
