I plan to use a Atom Pro + Botboard II for a glorified I/O board. I also plan to use a SSC32 for (obviously) a servo control board. My desktop is where I plan to run the majority of code. Initially, it will have two (or more) serial cables connecting the bot to it.
How do I do a dual serial wireless link? Oh, and range wise, I want it to be able to traverse the apartment (at a minimum), so I don’t think bluetooth will cut it (my bluetooth headset cuts in and out if I walk around the apartment)
Lantronix WiPort is the most straight forward however it’s probably between around $150-$175 USD by the time you get a module, a carrier board, and an antenna. On the good side it is two high speed serial ports (up to 930kbps) on a WLAN port that will do somewhere around 300’ indoors and 1300’ outdoors. Runs on 3.3V and about 350mA when the WLAN is active (which is much of the current as I also have a NR version that’s less than 200mA with the ethernet port active, heh.)
The pins are 5V tolerant, meaning you can connect 5V outputs to them and their output level will meet the TTL thresholds of 5V logic. Usually the carrier board will have the voltage regulator on it so you just power that from the 5V or whatever.
I have been looking at both the matchport and wiport from Lantronix, and maybe my information is incorrect, but on gridconnects site gridconnect.com/wpvsmp.html
they say that both the wiport and the matchport support 2 serial ports up to 921Kbps each. Did I miss something, or is their site wrong?
I don’t recall that the matchport supports 921kbps, I think I remember it being only 230kbps, but they may have upgraded the product since the last time I bought one.
actually, looking here though they say it does so that’s a nice bargain over the wiport unless you plan on developing your own embedded device server applications.
I am going to be soon placing an order for the matchport along with the demo board that they sell, myself I need 2 serial ports that I can control over WiFi, and this seems to be the best option for what I will be doing.
Last year I remember reading that it was only 1 serial port at 230kbps, but cannot seem to find that information anymore, they must of made changes somewhere along the way
