</div>This is a good test, only if your sender is operating on channel 6.<br>

You say it doesn't return ffffffff. What does this test do instead?<br>
<br>
I have tested here. If the multinand-traffic? command is not<br>
returning ffffffff then it should return 0 (zero).<br>
<br>
If it returns zero, then it is because there was no multicast traffic<br>
received with a valid multicast address.<br>

Do you see zero, or does it not return to ok prompt at all?<br></blockquote><div><br></div><div>It returns to OK prompt. No 0 or any thing.</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

</div>Thanks. I have tested with two XO-1 and see identical trends.<br>

What are your results in average RSSI dB, with antenna uncovered?<br></blockquote><div><br></div><div>I also have access point in another room 10m away.

Here are my results. Numbers are average RSSI dB after 10 seconds.<br>
Access point is in another room 10m away.<br>

Test start, SKU1 -59, SKU39 -56.<br>
<br>
SKU1 covered left antenna -69, covered right antenna -68,<br>
SKU39 covered left antenna -66, covered right antenna -70.<br>
Conclusion: both antennas are in use.<br>
<br>
press 1, SKU1 -62, SKU39 -54<br>
SKU1 covered left antenna -62, covered right antenna -82,<br>
SKU39 covered left antenna -54, covered right antenna -71,<br>
Conclusion: right antenna is in exclusive use.<br>
<br>
press d, SKU1 -59, SKU39 -56<br>
SKU1 covered left antenna -76, covered right antenna -75,<br>
SKU39 covered left antenna -62, covered right antenna -66,<br>
Conclusion: both antennas are in use.<br>
<br>
press 2, SKU1 -62, SKU39 -56<br>
SKU1 covered left antenna -64, covered right antenna -77,<br>
SKU39 covered left antenna -55, covered right antenna -70,<br>
Conclusion: right antenna is in exclusive use.<br>
<br>
press d, SKU1 -61, SKU39 -57<br>
SKU1 covered left antenna -74, covered right antenna -66,<br>
SKU39 covered left antenna -63, covered right antenna -69,<br>
Conclusion: both antennas are in use.<br>
<br>
press 0, SKU1 -60, SKU39 -57<br>
SKU1 covered left antenna -75, covered right antenna -70,<br>
SKU39 covered left antenna -66, covered right antenna -67,<br>
Conclusion: both antennas are in use.<br>
<br>
press d, SKU1 -61, SKU39 -57<br>
<br>
press l, SKU1 -62, SKU39 -55<br>
SKU1 covered left antenna -62, covered right antenna -77,<br>
SKU39 covered left antenna -55, covered right antenna -69,<br>
Conclusion: right antenna is in exclusive use.<br>
<br>
press d, SKU1 -60, SKU39 -57<br>
<br>
press r, SKU1 -62, SKU39 -54<br>
SKU1 covered left antenna -62, covered right antenna -82,<br>
SKU39 covered left antenna -55, covered right antenna -67,<br>
Conclusion: right antenna is in exclusive use.<br>
<br>
press d, SKU1 -59, SKU39 -56<br>
<br>
Overall conclusion: XO-1 SKU1 and SKU39 have diversity receive and can<br>
also be configure for right antenna only. The test cannot configure<br>
for left antenna only.</blockquote><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

Therefore this test is not very useful to you, sorry!<br></blockquote><div><br></div><div>No worries :) . I think I should once send this XO for maintenance. Any other checks you want me to do before that?</div><div> </div>
