I bought 4 RS&BOOMs in this April, and I bough 4 GPS antennas in May.
RS&BOOMs work fine with NTP servers, but, they cannot recognize GPS antennas.
To be a little more precise, if I check /var/log/messages, the GPS antenna is recognized as a USB device, but, /dev/ttyUSB0 is not created.
My colleague also have your GPS antennas which bough in this March with RS4Ds, and they work fine with my RS&BOOMs.
From your website, it says “Fully tested with the latest software updates”.
According to the manual, I connected my RS&BOOMs to the Internet and rebooted once.
But, they still cannot recognize GPS antennas I bought in May.
How can I check my RS&BOOMs are updated or not?
What more should I check?
