Good day to all,
Firstly, I want to apologize if I'm writting in the wrong forum.
Now, on to the business. I have bought a GPS Bee kit (a u-blox Neo 6M gps module in a XBee compatible board) and I'm having a huge headache thanks to it (photos of the module are in the attachments).
The problem is that it appears to "see" satellites, but never gets a fix. Right now I'm using it with PL2303 USB - TTL UART converter (see attachments), connecting them like so:
Converter - GPS
RX - TX
TX - RX
3v3 - 3v3
GND - GND
I'm completely sure that there is no wiring problem. I have 3 modules like this and all of them have the same problem. I'm using u-center software to see what the gps receiver sends to the converter. The gps usually "sees" 1-3 satellites for several seconds. The strings output repeats over and over in the same pattern which is giving no information (see attachments).
I have googled, watched videos, read forums for several days now and I'm at a loss.
Things I've tried:
1. Going outside to get as much open sky as possible (for at least 3 hours);
2. Connecting it to Arduino, uploading a working and tested program to get the same result (see attachments);
3. Changing the baud rate (even though I'm completely sure now that this gps uses 9600 baud);
4. Switching connecting Rx to Rx and Tx to Tx achieves nothing, the receiver doesn't even communicate with the converter (the receive LED doesn't flash when connected like that);
5. Trying 3-4 other gps programs which show the same result (satellites appear for a moment and disappear, same empty strings);
6. Doing everything i could find that other people did (going through settings, modifying them, tinkering with the firmware etc.)
That's some of the things I've tried. ALL and ANY advice is welcome. Thanks for taking your time to read/answer.
P.S. I would have bought other gps module, but these are the only ones they've got in our country (Lithuania) and I have just 2 more weeks to complete my work, so ordering other gps units from abroad is out of question. :|
