Alan,
Do you know where I could get the other SIRF tools (SiRFGetEE, SiRFView...) ?

There is a command line for changing "Message Rate" on NMEA? I want to start GSA=1 and GSV=1 on my Navigon with a script before launching the Primo or iGO8 to have the possibility to see the signal bars on this applications (for now, Navigon is starting only GGA and RMC).
Thanks! |

Hi,
Can anybody explain to me what the output in sirf mode in the debug view of SiRFDemo exactly means? I mean those:
Unk: 4002131400........00000002
thanks in advance,
jeensii |

Not enough data. With some 1-2 KB it would be easier.
Basically this message means that SiRFDemo was unable to detect neither NMEA format nor SiRF binary format. To my eyes this definitely isn't NMEA, too many non-text values. As for the binary, the protocol allows to craft a packet that's 32 KB in length and still valid, and a packet boundary would not be found earlier.
But in practice this is more similar to a bitrate mismatch. SiRFDemo likes to switch to higher bitrate among with the binary protocol. Some Bluetooth modems support a single bitrate only and in such case communication becomes impossible until the entire GPS receiver is reset properly (for example, by disconnecting the internal backup battery). |

The message that says Unk: 4002131400........00000002 means that SiRFDemo has parsed a binary message, removing the header and trailer, but that it doesn't know how to interpret the payload. SiRFDemo has been replaced by SiRFLive for newer chips like the GSD4e, so it was never taught how to interpret message ID 64, subID 2 (0x40 0x02 for the first two bytes).
MID 64 is the new message group of advanced navigation library data. |
