1. Your suggestion of using the Mini GPS app to configure the GPS is excellent and it works. While I was using it, I noticed item #2 below while I was changing the setup values.
- When you query the GPS or issue a command to it, the result isn't immediate. For example, when I issue a Test Packet request while the unit is sending location info, the $PMTK result happens later--sometimes right away, sometimes after several location info packets have been sent.
Another example: When I send a baud rate change, the GPS output will continue for a while at the old baud rate. The commands are probably queued in the device.
It's easy to parse the return string to get the desired result.
This is a great product. It's especially useful for learning to use GPS. It would be a perfect world if the GPS would work INDOORS like my iPhone and iPad do. If you ever sell an active antenna with sufficient gain, I'll want one.
