After some hacking, bluetooth networking is working well.

Initially tried the antennas bluetooth access points on a metal pole mounted on the NW corner of the base trailer. All three access point radios were on the same pole.

...

Later found two issues that might have prevented good connections:

1. a bug (mine) in the blue_check.sh script on the DSMs, where it did not restart the pand process if ping failed
2. some of the dipole antennas on the radios were not screwed on tightly. I didn't note which stations.

Those 6 sites had pretty good LOS. However other sites which also had good LOS did not come in, which may have been due to the above 2 issues. The dorm buildings were in the way of line-of-site to 5,6,7,9,10,11,12.
None of these sites with poor LOS was were received.

The WIFI AP24 was also mounted lower on the same pole, and was transmitting, successfully connecting to the ISS-SODAR Etherant EantH.

After lunch, moved the bluetooth radios over to the deck on the back of dorm #2, which has good LOS to all sites. The pole was just bungied to the step railing. AP3 was at the level of the railing, AP1 about a foot above that,
and AP2 about 3 feet above the railing.

Lo-and-behold, only the same connections came in (1,8,13,14,15 and 17), but, initially at least, no others.

Went out to site 4 and discovered the issue with the blue_check.sh script. However, then noticed that several stations started connecting by themselves, despite the bug in the script. So I believe the communications are better from the dorm deck than from the pole on the trailer. To work from the trailer, I believe the radios would have to be raised.

Note that RSSI is a relative number, and can't be compared between the two types of access points.
