The good people at HumaRobotics sent me a prototype WifiBlock to develop a leJOS driver around. I’m working on this in parallel with the NXT2WIFI driver, so it’s interesting to compare both sensors.

Any progress on this? Maybe a beta version? I’m in the middle of chosing a wifi sollution for a Lejos based bot.
Could you give more info on the http get/post possibilities, which would be fairly high level functions (which I’m after) compared to the Lejos enabled wifi competition, for which the coding is pretty low-/bytelevel. (as far as I’m able to judge given the information I found on the web.)
I’m planning on building a robot that would need to fetch wheather data from a webservice.

Hi Bob, sorry it took me so long to respond. I’ve had this sensor sitting on my desk for a few weeks now and have been busy with other projects. I hope to get to work on it soon, but no progress yet. I wrote a leJOS driver class for the NXT2WIFI sensor, and also have code on my website for the Dexter dWifi sensor.

Hello, I’m French student working on a lego nxt mindstorms which run on the leJOS firmware 0.9.1.
I would like to ask you if you have done the leJOS driver for the wifiBlock?
I have seen you have worked on the 2 others wifi-sensors (Dexter Industries DiWifi sensor and NXT2WIFI sensor), in your opinion which one is suitable for a p2p (robot to robot) connection?
I’m looking for your answer.
Yours sincerely,
Angelo

Hi Angelo,
To answer your first question; yes I developed a driver for the NXT2WIFI in leJOS which is now part of the official source tree. Danny Benedetelli (who invented the NXT2WIFI) has improved it further since I checked it into leJOS.
In answer to your second question; both sensors will allow robot-to-robot communication but it depends on what other features you require. Will you need a wireless base-station? If not then the NXT2WIFI can operate as a wifi hub. The NXT2WIFI provides a built-in web server but the Dexter device does not. However if you are doing P2P communication then a webserver does not matter, so the devices are identical.
Ultimately it may simply come down to price and availability. Given a choice between the two I would say that the NXT2WIFI is slightly better than the Dexter wifi as it has the built-in webserver.
Let me know how your work progresses!
Mark
