Hi,
I have the BS2 connects to computer with USB...
Rev B...idk
The GPS reciever is revision 2.3
The *.pdf file has sample code and says how to wire this thing up...
GND - Ground
VCC - +5 volts
SIO - pin 15
/RAW - connected for raw data, not connected for smart data....
The thing is I get the following with raw connected....::::::::::::::::::===>
Parallax GPS Receiver Module Test Application
Hardware Version: 8.9
Firmware Version: 8.9
Signal Valid:
Acquired Satellites: 767
Local Time: 09:09:38
Local Date: 43 2042
Latitude: 098° 98' 51.1" 8 (98.5829 )
Longitude: 137° 01' 12.7" ' (µ137.1323 )
Altitude: 928.7 meters ( 3044 feet )
Speed: 3514.5 Knots ( 4044.3 MPH )
Direction of Travel: 1053.8°
thats fine & dandy.....and the numbers are all incorrect ALSO......
when i disconnect raw i get.....:::::::::::======>
Parallax GPS Receiver Module Test Application
Hardware Version: 1.0
Firmware Version: 1.0
Signal Valid: No
Acquired Satellites: ?
Local Time: ?
Local Date: ?
Latitude: ?

This is where it says the ? marks and the No....
I want a Yes and a numbers..... [noparse]:D[/noparse]
I do not understand how this is hapening....
It is sample code properly wired up.... and i even tried the 1.1 sample code off their sight....
FAIL.....
anybody have any Ideas as to why it gives incorrect values with /RAW grounded (LOW), and why it gives ??? with /Raw not connected (HIGH)...??????
Also, any ideas as to how to fix this errors....?????
i do what it say and fail....
I am knew to using GPS and cannot really figure this out...
Kinda dum of me, considering i can program quite a bit of parallax stuff on a bs2.....
And, I post because i googled ALOT and could not find anything relating to this......
Thanks,
Buster

that red LED is blinking slow...
never has been solid, ever....
I am right next to a window....idk if that means anything....i will try it outside....
if this happens so easily, in a building, then what if I am outside...?
Line-of-Sight....
Trees?
powerlines?
i have everything thats connected setup and working properly, but the GPS, fails for now...
I am making a portable GPS reciever thing, for fun....
will try outside soon....
maybe I might get lucky....
but even though i am at a window 5th floor....
I try and get back if it works outside....

I got the verdict....
the LED still flashes slow....
The GPS still outputs the ??? marks like before....
and I do not understand....its correct code.....? right?
I post my code that I found online on parallax's sight for that to see if something is incorrect....

Same way it acted as inside....
I even walked to an open area where i could try this away from buildings...
I am using the 4 AA batteries in series to power my BS2.....
I just do not get how this isn't working still.....

If you keep watching the light waiting for it to get a lock, the onboard "watched pot" detector will keep it from ever getting a good signal. You have to go away and come back.

It works [noparse]:D[/noparse]
I was just a bit impatient and did not notice the different pulses in the LED....
Here is what the thing did...::::===>>
1- Power on Slow Flashing, NO SIGNAL...
2- Faster Flashing, just a bit faster, Aquiring signal.....
3- Solid LED, Connected, now you don't have to worry, once connection starts it is gona stay...
***it is dificult to establish connection, it is picky with its line of sight....IDK...it just is....
***And, once the connection is on, they all know what each one is and wants...so, they will stay but enough interference will cause problem....lol
sorry about the troubles but I'd have neva have learned unless i went through all this yackin'.....
:P
