Cannot configure telescope with NexRemote external software

[Scott Loucks]

Hello, I recently upgraded to vs 17 from vs 15 and lost telescope connection. I have a Nexstar GPS11 mount and I am connecting to the PC with NexRemote and usb to serial adapter. The Stellarium connection type is external, Nexstar compatible mount with jnow selected and startup button checked. When trying to connect the status reads: "connecting" however it never connects, just hangs there with same status.

Prior to this incident, I was successfully running this same exact setup with vs 15 with no issues. Maybe I have missed something on the configuration process but I cant find my mistake if I have. Stellarium is truly a superb software! I do hope this issue can be resolved.

Thank you -Scott

v0.17 introduced INDI telescope support. We unfortunately cannot test the necessary changes this move brought in, because we (2-3 active developers) do not have the telescope mounts required. You can try to run your telescope now via INDI. Hopefully the old functionality can also be restored (or checked again what happened).

Georg, thank you for your answer. I will try the INDI connection. If this doesn’t work maybe I can try an earlier version of Stellarium.
Can you tell me what becomes of this issue, will the status remain open until hopefully it can be addressed, or do I post another bug report at a later date?
Thank you for your help.

No, this bug report will stay in open state, but it is unclear when we can deal with it. I have a small NexStar compatible mount, so when it really does not work, I am affected myself, bothered and annoyed by this fact and will be possibly motivated enough... But my time budget is limited, so it may be February or June. I spend considerably more time developing this simulation than getting starlight :-( If INDI does not work for you, V0.16.1 should have the same connectivity options as 0.15.

I assign this bug to myself just to remember, but if anybody else want to solve it, I am not unhappy.

I am attaching the log here if it helps. The log shows attempted
connection, external local, with NexRemote loaded and running. I did try
INDI connection but that did not work either - not included in log.
Thank you for your support - Scott

As a follow up, I have successfully made a telescope connection via NexRemote. After stepping down versions of Stellarium, vs 17 to 15.1 while trying various connection settings I finally connected with vs 15.1, which I believe was the first version I was using before trying to upgrade to vs 17. In any case, the connection type I finally used was not “indirect” as is suggested for a remote software connection, but rather a “direct” connection. I had to set my mount type (Nexstar) and configure the port setting. I used the current NexRemote virtual port (Com 2) for the port setting.
By the way, this type of connection did not work on any subsequent versions of Stellarium. Neither direct or indirect. My memory is a little rusty but I believe I had made the this same “direct” connection months before and thought it was odd then too but it worked so what did I care. So there you have it! I know I didn't fix anything but maybe this will offer some clues. I can't code but I sure can hack.. ;-)

Hope this helps in some way
