I thought, it would be a really great idea to port the GPSd server over to the .Net Micro Framework. For those unfamiliar with .Net MF, have a look at http://www.microsoft.com/ne... What I was trying to achieve is a low cost hardware solution to proving a GPS that broadcasts itself on a network. I needed to build something that would run on a low power device with no screen just an Ethernet connection and connectivity to the GPS. Porting the GPSd, was very straight-forward. I produced ......

As promised yesterday, here is the complete source for the moving map solution. It is arranged as two visual studio solution (GPSd, GPSdMovingMap). The project files within the solutions are as follows. - GPSd Solution -- GPSd - Windows Service, that connects to and broadcasts a GPS. Configure the COM port of the GPS you wish to attach to in App.Config. In addition a fake file can be specified if you wish to test without real GPS hardware. The service writes to the application event log, if you wish ......

So I thought, ahead of new year, I should just prove end-to-end the components of the GPSd service. What better way than to plot our current position on a map. Using a converted version of the GPSd client, that we talked about previously, I parse the NMEA data coming from the GPS and produce an XML file of the following - <?xml version="1.0" encoding="utf-8" ?> <movingmap> <latitude>51.267</... <longitude>-1.108<... <bearing>182</bear... ......

Just to prove that it can be done. Here is a GPSd client running on a mobile device. I'm just getting the raw stream of NMEA data out of the GPS (which is the whole point of GPSd). Obviously the client can then use this data for its own purposes. To make the example shown work, I have laptop connected to home wireless network and in turn connected to GPS via BlueTooth. The Windows Mobile device is also on my wireless network and picks up the GPSd server running on the laptop. The fun part of the ......

So back on the topic of GPSd, I thought it was pretty wasteful to have the GPS device broadcasting to the world if no machines are connected to the service. So today I implemented a feature that monitors the number of connections to the service and only starts the GPS connection when the first client connects. New version HERE ......

Ok, last post I talked about the possibility of being able to subscribe to a published GPS. Well I've only gone and done it. I've built a small GPS server that broadcasts the data from a connected GPS. This is the server running - To attach type TELNET localhost 2947 at your favourite command prompt. You'll see the GPS being broadcast like so - (looks about the same doesn't it, which I guess is the whole point) Full Visual Studio project - Here Let my know what you think? Its a multi-threaded server, ......

First up, if you don't know what Geocaching is, then please do yourself a big favour and look at www.geocaching.com So..., Yes its an iPhone app, andI've been looking/building something similar for a while. Lots of GPS systems promise Geocaching options but they all seem to fall a little wide of the mark (or the ones that I can afford do) This could be the answer? http://www.geocaching.com/i... ......
