safari 5, skybt and skycommander XP4

 Hi, I have juste bought a SkyBT module to be able to see on safari pro 5 the position of my dobson scope (on my android smatphone) .

My Dobson is connected to a skycommander XP4, i don't succed to establish a link between safari and the skycommander, i  always have a message scope not responding or something like this.

I'm not sure to do the right thing, first i switch on the skycommander, when i finish the initialisation mode (2 stars method), i connect the RS232 cable into the SC (the serial cable provided with my skycommander to be set with a pc), i connect him between the skycommander and the skyBT then i switch on the skyBT (green light) but when i want to establish the link, i always have the message "scope not responding"...

Safari settings seems to be right (push to, alt AZ, choice telescope is skycommander), i don't no what to do, perhaps the serial cable is defective?

My phone see the SkyBT module and can appaired with it...

Regards

Vincent

    Vincent,

    Generally when this happens, it is because you have the wrong or defective serial cable.  Have you verified that you can still use this same cable with a PC?

    If you are sure the cable is correct, you might using the "Basic Encoder System" to see if that works.

    When you try to connect, are you seeing a change in the flashing light on the SkyBT?  Is the Android device is really talking to SkyBT, you should see some sort of change.

    Hi

    I will try to test the serial cable with my pc to verify if it is normal, i see there is a upgrade for skycommander but i hesitate because if the cable is broken...

    What do you mean by "basic encoder system"?

    When i try to connect safari, after few time, the flashing light seems to become fix light during a little moment.

    What is the exact swich on sequence i must do:

    Bluetooth on on my phone, skycommander on (date, initialisation and else), plug the serial cable between Sky BT and skycommander, switch on the SkyBT and finally try to connect safari, is that correct?

    On safari pro 5, i obtain this message

    "SkySafari Can Make A Wireless Connection To The Scope But The Telescope Is Not Responding"...

    Don't know what must i do, perhaps skycommander have a bad baud rate?

    Basic Encoder System is one of the scope types.  It is several entries above SkyCommander.

    Ok, good that the light goes steady for a bit.  That means you are talking to it.

    The sequence isn't critical.  I generally tuen the scope electronics on and then turn connect the SkyBT and turn it on.

    We automatically set the baud rate.  You should not have to do that.  Also make sure all the switches on the SkyBT are pushed in the direction of the red button.

    I have juste discover something, perhaps i must intervert the two extremity of my cable like explain here...

    On possibily for upgrading the skycommander and the other possibility to do serial communications with other astronomy program or pc...

    Hope it  wil solve my problem.

    Problem solve, in fact the baud rate of my skycommander XP was over (only 60 bauds!!!), i put 9600 bauds then safari and skycommander can communicate normally.

    Thanks

    Glad that was it.  I wasn't aware you could change the baud rate on the SkyCommander.  We always assume it is 9600.
