Hi Fréderic,

Could-you please give me also the type of WiFi you have ordered ...?

Thanks.

Hi Bruce and Fréderic,

The "WiSnap Embedded Kit M1" buyed by Bruce, is based on the Rooving Network RN-131G “WiFly GSX” 802.11G Module !
See : http://www.sparkfun.com/datasheets/Wireless/WiFi/rn-131G-ds.pdf

This module is a 3,3 V UART ...

Not shure that this will work without Level Shifter ( to 5.0 V for the Merlin...)
Must be investigated !

Hi Guys,

I talked with the SerialiO Tech support... Frederic and I were sent the same WIFI kit.

I will make the first tests with my Tronisoft module, which will also power the wisnap module. If all works fine, it will be time to think about a better solution.

Hi all,

If it work and if a lot of peoples are "really" interested in such a Wifi connection, I can try to devellop a WiFi module P&P with Deltawave .... ;)

Hi Guys,

Did your ideas work? I'm sitting here with the Skywatch mount. I have the WiSnap Embedded Kit M1. So what do I do next?

Alexandre will give me the WiSnap module this saturday...

If you want to help, you can find a way to connect to the Wisnap module in ad-hoc mode from a PC/Windows. I already found a documentation to configure the N800:

http://pacadi.blogspot.com/2007/04/nokia-n800-linux-laptop-ad-hoc.html

but don't know how to do this from Windows...

I will also explain you how to configure the Wisnap, and make some tests without the Merlin/Orion head. Stay tuned.
Frédéric

Ok, here is how you can test the Wisnap module. As Claude pointed to me, this is in fact a Roving Network RN-134 module.

To switch it in ad-hoc mode at startup, you can either configure it from the serial line, or pull the PIO9 line high; this pin is on the J1 jumper bloc; I think you just have to put a jumper here. The module will start with a SSID like 'WiFly-GSX-XX' where XX is the final two bytes of the devices MAC address. Its IP address will be 169.254.1.1. See docs below.

So, you will have to configure your PC so it can connect in ad-hoc mode, using this SSID, and give it an IP like 169.254.1.2 (netmask 255.255.0.0). Once it is done, you should be able to connect to the module from the Windows network tool.

Next step, connect the RS232 port of the Wisnap to your PC RS232 port, and launch a terminal listening on that port (9600-8N1); then try to establish the connection in Papywizard using the network driver, with the following values :

Host/Port: 169.254.1.1/2000

Papywizard will fail to connect, as nothing will answer, but you should at least see something on the terminal (I wrote a Merlin/Orion and PixOrb simulator, but it is not packaged for Windows; I will add it, but it is a command-line oriented tool only).

In any case, keep in mind that you will need a level shifter to either convert Wisnap RS232 signals to Merlin/Orion TTL (5V) data line (like the Tronisoft module), or Wisnap TTL 3.3V to Merlin/Orion TTL 5V. As I have a Tronisoft module, I will just connect it to the Wisnap. Claude and I will try to find a solution without this module...

RN-134 module docs:

http://www.rovingnetworks.com/documents/rn-134-ds.pdf
http://www.rovingnetworks.com/documents/WiFlyGSX-um.pdf

Important: I didn't test this procedure. Please check what I said, especially for the hardware part; any mistake can destroy your module!

Hi Bruce, I am waitng for inpout of Fréderic so we can give the "go / NoGo" for a first design and prototype ... :)
A proto is allways expensive also for small stuff and I want avoid "trials & errors" !
I am shure that you understand ! ;)

So, Alexandre gave me the Wisnap module, yesterday, after a great presentation of Autopano during the OGM of the UR11 (our local comitee of photography).

It worked out-of-the box using my RS232-TTL interface (Tronisoft) :) :) :) I only tried it from maemo (N800), where it is even more simple than I thought (just launch the network connection utility, and the module appears like an access point). I will make some more tests under Windows and linux to confirm that it works fine too.

As this module needs an additionnal PCB with some electronics, I think the best solution is a Tronisoft-like module, because such module can be used with a large variety of converters, or even to directly connect the head to the PC serial port.

Hi Frederic,

Thank you very much for the update. Thank you for your help. The only question I have is their any substitute for the Tronisoft RS232-TTL interface that can be bought in the US? As you know Tronisoft is difficult to deal with in the US. I found this one will it
work? http://www.gridconnect.com/ttl-rs232.html Hope you have a cheaper idea.

Many Thanks,

Bruce

I think you can find a cheaper product. And try to find one which has only screw jumpers on the TTL side, and which can direct power supply (5-12V) to the RS232 DB connector (pin9) to power up the Wisnap module...

In fact, you only need a few components: max232 and power regulator. Have a look a the first interface I built:

http://www.autopano.net/wiki-fr/action/view/Image:Merlin-interface-bus-serie-schematic1.png

You don't need the DSR/CS line, and transistors can be replaces by 220Ohm resistors. I will try to make a new schematic...

Ok, here is a simple RS232-TTL interface. I didn't test it, so...

If someone wants the Eagle project, I can send it.

I tried to connect to the Wisnap module from Windows, and it works without problem.

On Linux, just run the following commands (as root):

Code: Select all
# iwconfig wlan0 mode ad-hoc
# iwconfig wlan0 essid Wifly-GSX-xx
# ifconfig wlan0 169.254.1.10 netmask 255.255.0.0 up

Replace wlan0 with your own wifi interface name, and xx with the last 2 Mac address digit of your Wisnap module.

Note: in any case, don't forget to put a jumper on the module pin 1 to enable its ad-hoc mode.

Here is a new version of the RS232-TTL adapter, dedicated to the Wisnap module (it can be plugged on this PCB). Again, I didn't test it!

Hi Frederic,

I found this US site. http://www.futurlec.com/Mini_RS232_TTL_3V.shtml Will the 3v or the 5v work?

Hi Frederic,

I received the Futurlec boards today. They came from Bangkok. Looks good. Keep your fingers crossed. I bought 3 of them. They were cheap.
