Quick udpate: Yes. it works having two BT connections. What seems critical is to leave a few seconds in-between the two bind commands. So my rc.local file looks as follows:

#!/bin/bash
#
# rc.local
#
sleep 10s
rfcomm bind 0 20:17:12:05:05:02 1 ###this is for the Shoestring BT adapter (attached to the mount)
sleep 5s
rfcomm bind 1 00:14:03:05:ED:80 1& ###this is for the HC05 module connected to the Tic825 stepper controller
exit 0

So far it seems to be working, via rc.local. First tests look promising. Many thanks!

A bit tricky was to get going with the rc.local method under Ubuntu 18.04. Found good guidance here:

Hi,

It may sound trivial, but if I was running a second Bluetooth device, I should repeat the procedure as described, and regarding the systmed file, I would add another line, like
ExecStartPost=/usr/bin/rfcomm bind rfcomm1 XX:XX:XX:XX:XX:XX

However, binding is not working. I suspect I need to allow more time for the binding of the first device? What command do I need, how many seconds were needed?

What happens, if the first device is not there, would that create some sort of error, preventing binding of the second device?

Many thanks, Helge

Maybe you can also address by increasing the current allowed for the USB port that the WiFi stick is attached to?

BTW: why WiFi? What pi are you using?

Hi Max,

I have a similar set up and no problems. How is your ASI cam connected - via USB to the Pi or directly to your mount (ST4)?

You may have seen this Tutorial and know this already, which describes the two methods to connect:

I have connected the ASI cam to the host computer. In the Guide Module I selected Via: EqMod Mount.

Best, Helge

Hello and happy new year,

I have uploaded to github my FreeCad file and some other information on how a bracket and gear-wheels can be built for a nema17 stepper motor with gearbox (1:14 in my case).

Hope this can help and welcome and thoughts or suggestions.

Hi AstroNerd and happy new year!

I am very curious how it works - I would have thought, but do not know, that using the GPIOs of the Pi instead of the USB interface will require another driver that addresses the Pi‘s GPIOs. This is why I was pointing you to the astroberry-diy repository. However, could be that in your case, specifically for the TX/RX and V, GND it does not matter.

It might be necessary to also update the file /etc/default/gps (or similar).

Best, Helge

Hi AstroNerd,

Maybe you can leverage on the astroberry-diy drivers (here GPS), at least the description (readme) might help:
