hi!
I am developing a Raspberry Pi drive controller and autoguider; I am right now implementing the LX200 basic protocol using the RS 232, and I have a question. KStars send an <ACK> when connecting via the telescope wizard and is happy with a reponse like 'P', and starts polling the position by issuing #:GR# and #:GD# - that works nicely ( ). but i don't get any commands when issuing a sync or slew command - what am i doing wrong (it works nicely with carted du ciel and stellarium, that's why i am asking ...)

Who is not receiving what commands? On Sync/Slew, KStars first updates ON_COORD_SET then sends EQUATORIAL_EOD_COORD to the driver. Are you implementing a new LX200-based driver? or what?

hi!
i am developing a telescope controller (that is, an interface to stepper drivers) based on Jessie and the Pi - github.com/selste/TwoStepperControl )...

my question is not directly related to INDI but to the RS232 connection of Kstars to the controller. when i connect my ubuntu 14.04 laptop via a nullmodem - cable to the Pi and i instantiate a LX-Basic connection via the telescope wizard in KStars, i get
<ACK>
which I answer with 'P"

after that, KStars polls Right Ascension and Declination by sending #:GR# and #:GD# ... i answer with the appropriate strings and KStars displays these coordinates, as seen in the video. but when i deploy Sync or Slew -the other two available commands, i don't get a request by KStars, it just keeps polling RA and Decl.

When issuing Sync/Slew, the driver first sets the coords #:SR# and #:SD# IIRC, and then following that by either sync or slew (#:MS#) commands. Please enable the logs and you'll see the LX200 basic driver issuing them to the serial port.

hi!
sorry for not getting back earlier ... had to install the latest ubuntu (was running 14.04) and the latest KStars. now i do get sync or slew commands, but my replies are apparently not accepted from kstars now ... here is my log. i got a slew command, but now i don't get requests from KStars for actual position. here is my log:

hi!
so i tried to figure out what is going on, and I programmed a little bit on my own controller; so basically, KStars seems to process my coordinate output not properly. when is start up my program, i get these requests from KSTars with the LX200 Basic driver over the serial port:

and i answer them properly (at least CdC and Stellarium can process my responses). KStars does not track the telescope, but it reacts to Sync and Slew commands in the LX200 Basic protocol. here is the log. what am i doing wrong?????

Logs looks fine, what is exactly not working now?

hi!
kstars does not track - the positions reported by my software are not translated to a crosshair position on the screen ...

Post the logs when you issue a SLEW command.

hi!
here it is. the issue is that, upon establsihing connection, i get 3 #:GR# requests and one #:GD# - which i answer - and then position is no longer polled. SYNC and SLEW are reported to my software and are carried out by the steppers ...

hi!
one thing just came to my mind ... when i look at
2016-12-29T17:37:39.370 - DEBG - LX200 Basic : "CMD <#:GR#> "
2016-12-29T17:37:39.457 - DEBG - LX200 Basic : "RES <00:02:11> "
2016-12-29T17:37:39.458 - DEBG - LX200 Basic : "VAL [0.0363889] "
2016-12-29T17:37:39.459 - DEBG - LX200 Basic : "CMD <#:GD#> "
2016-12-29T17:37:39.558 - DEBG - LX200 Basic : "RES <+00*00:00> "
2016-12-29T17:37:39.560 - DEBG - LX200 Basic : "VAL [0] "

it seems to me that commands are issued at a pace of 90 ms. assuming a baud rate of 9600, this is 860 bits at best. the response to #:GR# is already 88 bits - is there a possibility to tame the pace of requests over the RS232 line?

PS: could that be a related problem? www.indilib.org/forum/general/1780-mount...s-stopped.html#13400

This is never an issue when used with previous Meade based mounts. Here is the main issue as I see it:
Why are you returning 1 here for Slew?
