This summer I was paragliding at the Hochjoch (Montafon, Vorarlberg, Austria). It was a very exciting experience. If I had enough time in the moment I would start this Sport immediately. To log the flight I used my iPhone which I had in my pocket. I was surprised that the logged data was so good. (see map below)

Finally I was paragliding this summer…
5 Oktober 2009Exploring WiFly RN-131 GSX Embedded WiFi Module
3 Oktober 2009I made the next step in the direction of WiFi. Some days ago I surfed the Internet for an embedded WiFi module for less money. And finally I found the WiFly GSX modules from Roving Networks. Their slogan is “Wireless for less” 
So I ordered some evaluation boards (about 100€/pcs) for me and two collegues who are studying with me at the NTB. Our goal is to have fun with wireless applications.
The RN-131 GSX Module is a 802.11 b/g wireless LAN Module with a lot of features – Details see datasheet.
If you already have a GSX Module you can use my LabView source below to show the UDP packets which the module sends in default configuration every 7 seconds.
The packets include
- MAC address of AP
- WiFi-Channel
- RSSI (quality)
- local TCP port
- RTC (real time clock value)
- NTC temperature option (if temperature sensor connected to module – otherwise sensor 7)
- Spare sensor reading
- ASCII time
- Version string with date code and Device ID string
This information can be used to open a TCP connection to the module or to configure it over WiFi. The module has to be in the same subnet as your PC or MAC if you want to receive the packages.
Here are some pictures of the Module in action:
