<p>Dear Duefer,</p>
<p>Contrary to popular belief, Bluetooth is an awful communications
environment. And Bluetooth LE is even more pathetic. You do not
give a lot of information, so here are a few basic steps:</p>
<p>1) Make sure whether your Ratio used Bluetooth Classical or
Bluetooth Low energy (sometimes called Smart Bluetooth if you are
an Apple aficionado). It is critical that you have the correct
information. If you do not have the correct information (Classical
or BLE), then communication with your Ratio is likely to remain a
problem.</p>
<p>2) Make sure that the Bluetooth hardware in your laptop can see
the Ratio. Try to pair with the Ratio and see if pairing is
successful. If it is successful, then UNPAIR the connection with
your Ratio. The reason is that Subsurface performs its own paring
of Bluetooth devices, independent of the operating system. It
often takes many retries of the pairing process before your
computer sees the Ratio. Bluetooth is extremely temperamental.
Once Subsurface has paired with the Ratio, it is likely to
remember the information and subsequent pairing will be easier.<br>
</p>
<p>3) Carefully read the Subsurface user manual (especially section
4.2.2) and follow the instruction there. In particular, does
Subsurface see your Ratio when you go through the Bluetooth setup?
<br>
</p>
<p>4) Your screenshot looks like you may be running Subsurface on a
Linux box. You will have to determine in which directory your
Subsurface executable lies. Run Subsurface by typing: subsurface
-v -v</p>
<p>This produces the maximum amount of runtime information and is
printed in the terminal. In Windows you can use an analogous
process. On a Mac I have no clue. Carefully scan the debug
information in the terminal to find anything related to Bluetooth.
Then copy that information in an email to this mail group.</p>
<p>Kind regards,</p>
<p>willem</p>
