After completing the transmissions of the test link packets the executing radio will send the
following data packet to the requesting radio's Test Link Result Cluster (0x0094) on endpoint
(0xE6). If the requesting radio is configured to operate in API mode then the following
information will be output as an Explicit RX Indicator API Frame:
Example: Suppose that the link between radio A (SH/SL = 0x0013a20040521234) and radio B
(SH/ SL=0x0013a2004052abcd) is to be tested by transmitting 1000 40 byte packets. The
following API packet should be sent to the serial interface of the radio on which the results
should be out-put, radio C. Note that radio C can be the same radio as radio A or B (white space
used to delineate fields, bold text is the payload portion of the packet):
7E 0020 11 01 0013A20040521234 FFFE E6 E6 0014 C105 00 00 0013A2004052ABCD 0028
03E8 EB
And the following is a possible packet that could be returned:
7E 0027 91 0013A20040521234 FFFE E6 E6 0094 C105 00 0013A2004052ABCD 0028 03E8
03E7 0064 00 0A 50 53 52 9F
(999 out of 1000 packets successful, 100 retries used, RR=10, maxRSSI=-80dBm, minRSSI=-
83dBm, avgRSSI=-82dBm)
An error has occurred if the result field is not equal to zero; ignore the other fields in the packet.
If the Success field is equal to zero, then ignore the RSSI fields.
2 Iterations
The number of packets which
should be sent. This should be a
number between 1 and 4000.
