    Hi!


    I'm looking for documentation on how to use the $nearest_street TCP command, as its not covered in the documentation I've found.


     


    Regards,

    hi and thanks for this!

    Could you check to see if there are there any other undocumented TCP commands? Like end of sound notification, or resume navigation?

    Again, thanks, for this, I've added it to my plugin for Centrafuse integration. Works great!

    I did however manage to crash PC_Navigator.exe by sending a string like this: "$nearest_streets=0.00000,0.00000;1;10\r\n".

    Just a follow-up, $nearest_street commands don't appear to be very stable. PC_Navigator.exe (free, 12.3) has crashed more than a few times since I started using this command.

    Here's another string that will crash Navigator: $nearest_streets=-33.80346,151.12875;1;50

    The GPS location itself is valid, so not sure why it crashes?

    Would it be possible to make some changes in the next version to fix the stability issues?

    Hi John,
    I can confirm the bug - it was caused by memcpy of zero length buffer. You may try fixed version:

    thanks

    p.s. this command was originally for search of alternative street names, so that you always had one ...
