FINALLY I MADE IT... :)

 

Now I have a Home Made WiFi Module to control my Meade Telescope:

 

 

 

 

Unlike bluetooth version module, I did not have to reverse the pin 2 to pin 3 of the serial connector, I don't know why.

Hi everybody,

 

I'm trying to connect the Skysafari software to an Arduino board by using a bluetooth  module HC05. I'm using the LX-200 protocol.

 

I'm capturing the data send from the Skysafari, interpreted by the Arduino and finally sending the answer back.

 

This seems to be correctly working, I'm monitoring the messages in and out and there is nothing noticeable.

 

However, the Skysafari after sending three or four messages stops with the message 

 

"SkiSafari Plus can make wireless connection to the scope, but the scope is not responding. ..."

 

Well, the logs show that there are communication between them, so I suppose I'm missing something.

 

I attach the Skysafari log file in case could be useful.

 

Another interesting thing is that Skysafari starts its communication by sending three '$', I don't know the reason of this, and if is necessary to answer them.

 

Any suggestion???

Hi again,

 

I've found some useful information that can answer some of my doubts.

 

The three '$' are used to enter in the command mode of the wifly. They aren't used so they don't affect to the communication process.

 

Thus, the problem is about the LX200 messages returned from the Arduino. I'll continue looking for the solution.

Rumbert,

 

I think the problem is your returned Dec format:   s89*15# 

 

The specs say it should look like:

 

GD# Get Telescope Declination.
Returns: sDD*MM# or sDD*MM’SS#
Depending upon the current precision setting for the telescope.

 

That "s" is a sign character, not a literal "s".  Try making that +/- and see if that works better for you.

Thanks a lot, this silly mistake was the real problem.

 

Currently, both the SkySafari and the Arduino board connect an exchange data.

This Bluetooth serial dongle with builtin battery works out of the box and cheap.

I have HC06 module connected to NEQ6. It works nice with Smartphone apps like Virtuoso or PanoramaApp
Id doesn't work with Sky Safari. Actually its says that BT was paired but no response from NEQ6 mount.
Did you find the reason why SkySafari  fails ?

I have the HC06 working with my Atlas.  The HC06 needs to be connected to the hand controller via the serial cable that came with the mount.  The HC06 needs to be in slave mode and needs to be powered on before the scope.  For use with sky safari, I do not use eqdirect mode.  Just pair to the adapter and connect to scope in sky safari.  For eqmod use, put the hand controller in eqdirect mode, pair to adapter with pc, verify what com port the adapter is on, set eqmod to adapter com port and connect.

Need to mention that I have a null modem adapter between the bt adapter and 9pin to rj11 cable to swap the rx and tx pins.

With an Atlas EQ-G, do you align with the Hand Controller and then unplug the hand controller from the serial port and plug in the adapter? 

 

Or can you plug the adapter in the Hand Controller so you still the Hand Controller if you want it?

BT adapter gets plugged into hand controller using the cable supplied with the mount.  One thing that confused me at first, the controller has a feature called PC direct.  This is used if using the EQMod software on a pc.  In this mode, the hand control is disabled and all control of the mount (alignment, goto, etc.) is done via pc or a game pad connected to the pc.  You do not need to use this mode if using sky safari on a mobile device and the hand control will still work.

I ordered this adapter 

http://www.ebay.com/...=STRK:MEBIDX:IT

 

to work with a Sirius EQ-G mount. I havent gotten it to work yet. From this thread I believe I either need to send some commands to it from serial on my PC(my PC doesnt have a serial port) or I can just get a null modem adapter like this instead?

https://www.amazon.c...l modem adapter

 

 

If i need to send commands to this thing to get it to work, ill need some sort of USB to serial adapter. I just want to make sure im getting the correct items.

 

 

Thanks!

That looks like the same one I have.  I use mine on an Atlas, but I assume it would be the same for the Sirius.   I use a null modem adapter with my setup.  The chain is as follows: Bluetooth -> null modem adapter -> serial to rj11 -> hand controller.  If using sky safari on my phone, I will go through the alignment routine in the hand paddle then connect with SS.   When using eqmod, put the hand paddle in pc direct mode, connect using ascom compliant star chart via eqmod, unpark scope and go.

Also, don't forget to put the Bluetooth adapter in slave mode and turn on the adapter before the scope.
