Connection via Bluetooth to Celestron Advanced GT #35368

Hy everyone,

at the moment i try to connect my Celestron mount to my INDI-Server on a raspberry Pi 3. The connection of the Camera works fine, but the connection to the mount doesn´t work. My Handcontrol of the mount has a bluetooth-modul. So i asked myself if it is possible to connect the mount to INDI via bluetooth, but i don´tt now how. The only way to connect i can find ist serial or ethernet. Is there anyone who try the same and it works?

Greetings
Tim

Yes it's possible, if somewhat hairy. You can use whatever bluetooth manager your raspberry pi uses to pair with the bluetooth module and assign a COM port for it. However, it is mostly forgotten on the next boot. You'd probably need a script to make it bind to the bluetooth on every startup. If you search the forums, you'll find multiple posts on this very topic with ready to use scripts.

Binding to bluetooth at startup is a simple matter and can be accomplished in /etc/rc.local

rfcomm bind hci0 XX:XX:XX:XX:XX:XX 1 &

replace the XX's with the mac address of the bluetooth adapter on the mount.
Also uninstall Modemmanager.

sudo apt-get remove modemmanager

You will also have to pair the device with a bluetooth manager of your choice, but that should be a one time procedure and you set it to trust the device.

Tim reported he had successfully connected to the mount via bluetooth. The necessary steps:

- $ bluetoothct1
- $ default-agent
- $ scan on
- $ pair xx:xx:xx:xx:xx:xx
- enter PINs
- $ trust xx:xx:xx:xx:xx:xx
- $ sudo rfcomm bind hci0 xx:xx:xx:xx:xx:xx 1 &"

After that there is an rfcomm0 in addition to ttyUSB0.

It should remain. I have not had any issues with re-pairing or re-binding my bluetooth adapter. I actually used my homebrew EQBT adapter for a full night last weekend instead of my cable to test it out in the cold. No problems.

Hy everyone,

sorry for my late answer. The pairing of my Mount remains after evry boot. The only thing i have to do at every boot is $ sudo rfcomm bind hci0 xx:xx:xx:xx:xx:xx 1 &"

I´ve tested this many times. At the moment i try to find out, how this command run at every boot automaticly.

I´ll keep you up-to-date.

Place that command, without the " at the end, into rc.local
