We've had ups and downs on a17 today, suggesting that the intermittent data dropouts are a bluetooth communication issue. ping_test.sh does show in sometimes and then some long outages, and of course RTdata.
The station itself did reboot this afternoon and based on the /var/log/isfs/messages files has done so a few times in the last few days. Looking at the messages does show that the blue_check is finding lots of hci/down, restarts so for sure the BTRadio is dropping in and out. Since it's been a very windy today the thought was perhaps the usb cabling was loose, however, upon checking at the station that did not appear to be the case. I did put some cable ties on it and re-positioned the mote box slightly with a bigger tie as well.
Conclusion is we'll keep watching it and perhaps swap the radio if this continues.
