First release of 2019 comes with quite a few new drivers across the board along with significant performance improvements to INDI camera and live streaming performance. Many drivers received significant updates to improve performance & stability, while a few were re-written from scratch to be in line with INDI standards. Here are some of the highlights:

SOLVED - How Do I Chain Two Stellarmates so They're Seen as One by Ekos? was created by werper

I would like to use two Stellarmates to improve performance. One would control a Canon T3i DSLR camera for imaging, the second would control the mount (iOptron iEQ45 Pro) and guiding using a QHY5-II-M camera. I came across instructions on how to do this so Ekos (running as a remote client on a PC) sees both Stellarmate boxes as one, but try as I might, I can't find it again. As I recall, there was a simple command line you key in and you're good to go...???

Thanks in advance!

I wouldn’t mind doing this eventually, but for the different reason of having two imaging scopes on one mount.

Each StellarMate would control a camera/focuser, but the master would do mount control, plate solving, auto guiding etc. The main thing being the 2nd supports a pause while dithering on the master as well as having the same length of sub configured on the master and it applies to the other one.

Is this what you are looking for?

I was going to use a second sbc to control my mount via this method but ended up getting a bluetooth device to do it. Sounds like a neat way to share the load.

OK, I'm making some progress. I have edited the Hosts files on both Rpis and my PC and I can successfully ping each Rpi from any of the three by keying in their alias. I can also stat Indi Server with the correct drivers for my secondary Rpi server. However, when I start the primary server with the commands to link to the secondary, and then test it from my PC using Ekos, it's not working. Here's my set-up, sequence, and commands:

Setup:
Primary Rpi controls my Canon DSLR
Secondary Rpi controls the QHY guide cam and iOptron mount

Commands:
Step 1 on secondary Rpi: indiserver -m 100 -vv indi_qhy_ccd indi_ieq_telescope

Step 2: on primary Rpi: indiserver -m 100 -vv indi_gphoto_ccd "QHY CCD"@guide "iEQ"@guide

From my PC running Ekos, it will connect to the QHY guide camera and the iEQ mount, but not the Canon camera. When I try to start only the Canon driver, I get a message the address is already in use. Any idea what I'm doing wrong here - I'm assuming it's something in the commands I'm keying in...??? Also know that I'm a Linux noob, but VERY experienced with PCs.

Thanks!

Still trying to get this figured out, but when I try to chain the two RPIs together using the commands I listed above, I get a "BIND: address already in use" message. No matter what I try, it simply doesn't want to work. I can get both RPIs running fine individually, but I can't get them to chain to save my life.

Could it be that your primary rpi doesn't know where is "guide"? You did add a line in your /etc/hosts file on the primary rpi with "<ip-address> guide"?

Yes, I added both rpi's to each's host file, as well as my PCs.

On which computer do you have the bind error? As you may know, a bind error means another indiserver is probably already running.
You can use "ps -aef" in a terminal to obtain a flattened tree list of processes currently running.
Locate the INDI processes, check there are as many of them as you require, not more.
You can also use "netstat -l" to list processes that are listening to ports on your computer.

I get the bind error on the "camera" server, and that's the only thing that RPI runs. I've also tried making the camera the secondary server - same problem. Strangely, it starts just fine if I start it via the Stellarmate Web Manager.

Woo Hoo!!! I got it to work!!!

I had to reverse the order of the start-up syntax. AND, (this one's strange) I also have to start the Indi Server in Stellarmate Web Manager for the CAMERA RPI, then stop it, then close the Stellarmate Web Manager window - don't ask me why, but if I don't do this, I get a message stating - Bind: Address already in use - when I try to start the Canon camera server driver from the terminal. My guess is there may be a bug in Stellarmate Web Manager that's not releasing the port...???

Here's the syntax that works:

1) Start secondary RPI (named camera):
indiserver indi_gphoto_ccd

2) Chain to secondary FIRST and THEN start primary RPI server (named guide) devices:
indiserver "GPhoto CCD"@camera:7624 indi_ieq_telescope indi_qhy_ccd

For other people to use this, simply change the device names to the Indi names of your devices and also change the network name you assigned to your RPI/Stellarmate box (the name you used in your HOST files)
