    Default Serial to WiFi <> Wifi to virtual com port

    Hello All,

    I'm looking around for some serial-to-Wifi modules connecting to a Wifi virtual com port on the PC.

    The only product I found up to now is this one here: http://www.tronicore.com/en/serial-wifi-adapter

    This example shows an "ad-hoc" setup but I would also bee happy with an "infrastructure" system.

    I bought one of these for testing (not received yet) but their interface is too big to fit in the project I built already; in any case, I will have to find a smaller module.

    I might not be the best Googler on earth, but I'm surprised not being able to find more than this only example (...especially for a VCOM piece of software). Is the vocabulary I use for searching wrong? Does this system have a particular name? Is this not common at all?

    If anyone has seen/done/found something like this before I'll be really happy the here about

    Flotulopex I have used a product from ATC some time ago. It was an ATC-2000WF RS232/RS422/RS485 to WIFI convertor. It worked quite well. There are other offerings from company's like DIGI.

    I have set up the ESP05 and 12 serial to wifi modules (ridiculously cheap...$5, $7). Then had to program them to be "transparent bridge" so when powered up, they just act like a serial connection for send receive. And can program through web-settings to attach to your wifi network with IP and password. Pictured is a visual studio program to send and receive data to my 18F2550.

    Tibbo, Lantronix, Netburner and Wiznet do such modules. With the Wiznet I had some issues. Maybe because of the Power supply not supplying enough current. Never managed to make it work. Lantronix is my favorite though most expensive I suppose.

    Anyway, they all are in the logic of Serial to Ethernet and then your PC will run a piece of software to read the Ethernet and convert it to Virtual Com Port. Then your old software can just read the virtual serial port as if it was a real Serial data arriving from your Serial device connected locally.

    Ioannis, I also use the Lantronix RS232 to WIFI converters in my system at home. I haven't ever had any problems to date. I currently use about 6 of them.

    At 150 a pop, I should hope not.

    George, where did that 150 come from?

    OK, Lantronix are expensive comparing but the cable Ethernet to serial are around 50 and the Wifi to serial around 70-75.

    Other makers are cheaper of course. You can find from chine even cheaper.

    Just curious - why don't they meet your need?
