What's the chances of being able to use Socket WLAN Tools with the internal WiFi driver in a PDA2K? It is a much better interface and a lot easier to use. Is there anyone out there who can give this a try. I will wait in anticipation for a solution!

Hi all,
i need a special device driver that will use existing COM port and emulate another COM port and network card (i got some binary protocol on serial line which holds GPS and IP signal and i want split it in that device driver into virtual COM with NMEA and network card proving IP (Ethernet) interface or maybe another virtual COM with PPP emulation).
Have anyone got experience in such and can estimate effort of such task?
Maybe someone will be interested in a deal of developing such device driver?
Bets regards,
Chris
Look at Gpsgate, it may be what you need.
http://franson.com/gpsgate/
Thanks, it looks interesting - especially their SerialTools (with VPorts). It looks a bit clumsy with its variant datatypes (operating on binary data would be not as pleasant as with simple datatypes) but mayby i will give it a try...
Nevertheless - are there any other suggestions / propositions?
If you go to download site for gpsgate you will get the option to download many other utilities linked to the program, some are 7 day, 14 day or 28 day trials. The option comes via email.
I have a problem that I hope some of the code gurus here can help me with. I have an HTC PDA that was codenamed Colorado. The Colorado is actually the Dell Axim X50 series. I have a thread on Aximsite http://www.aximsite.com/boards/showthread.php?t=140071 where I am trying to add a USB host hardware interface to the PDA. I have done quite a bit of hardware reverse engineering of the X50v device (I'm a old-time hardware hacker) and have been able to bring out the PXA270 USB host port1 interface to the outside world via two unused pins on the sync connector.
I originally noticed that the X50v A02 ROM had the OHCI driver included, so I rolled back to that release on my test PDA and have been attempting to get the interface operational. In my quest, I have determined that I need the usbd.dll driver as well as any client device drivers for HID, mass storage, etc.
I've used a number of the great utilities I've found on this site (thank you very much) to grab a copy of the Axim ROM and pull it apart. I consider myself great at working on hardware but my software skills have become rusty over the years (hey - I started by building this system a 'few' years ago: http://www.sol20.org/ )
What do I need?
I would appreciate getting some guidance on how to dissassemble the ohci.dll module so I can see if in fact, it was designed for the X50 or if it was left in by accident by HTC as the later ROM updates for the X50 series had the ohci.dll module replcaed with one named peripheral.dll which was about 1/5th the size.
Also, I'm wondering if either the ohci or usbd drivers require the irq and/or the membase of the PXA270 USB host port1 interface and if so, how do I determine those.
My original idea was to use a simple 2 port hub to bring out the interface. Unfortunately, I recently discovered that a hub requires a hub client driver. Because of that, I will settle on getting a USB flash memory key to interface directly as the drivers are already available. One of the problems I have is interfacing the 3v USB host lines on the PDA to the 5v data signals that may be present on the client device. The PXA270 USB host lines are already terminated on the PCB with 15K resistors. All that is needed is a transient protection chip and/or port driver chip.
I have installed the free Microsoft WinCE dev environments which I thought contained the source for the generic ohci driver, but I can't find it anywhere so I guessing it's not included in the free dev s/w.
Although this is only my 2nd post here, I do hope to be able to contribute technical information going forward. What I'm doing on the Aximsite is quite advanced as far as hardware hacking goes and I hope to be able to simplify it so a few others can 'play'.
Thanks in advance for any help and I wish everyone here a great New Year!
Wow. Well this is a bit over my head, but does sound great.
I will try pointing you toward a couple of useful tools:
1st is IDA probably the most powerful disassembler for ARM code. The free evaluation works fine, but won't save and closes about every 30 min. Still should do the trick if you just want to look at the code.
2nd to get sample driver code, you need Platform Builder. Not sure if that is what you downloaded, but try the provided link. Evaluation version contains all the source code MS is willing to give, it just has some limitations on ROM compilation (which you should not care about).
The only problem is, it's a real b*** to install. Takes hours even if you have a goo internet connection.
Hope this helps.
Thanks for the quick reply.
Do you know if there is anyone who knows a little on how the low level device drivers actually interact with the hardware ports?
Also, I assume that with just the ohci and usbd drivers, if the port is actually activated by pulling one of the data lines high, I should get the popup box asking for the name of the device driver. correct?
how to determine I/O base offset?
In trying to reverse engineer the ohci driver for a couple for the HTC units, I need to figure out where the I/O register base starts.
Are there any memory dump utils, like dumprom, that would indicate that?
I've installed platform builder and want to try compiling the standard ohci driver, but I need to know how to determine the start of the I/O registers on a given WM2003SE platform.
Any assistance would be greatly appreciated.
thanks
Does anybody know if it is possible to connect the phone to a USB hard drive?
only with flame and Athena as they are the only ones which support usb host
other devices cant use usb devices only be used by usb hosts normaly a pc
There was actually someone who developed a working hard disk storage driver for windows mobile but last I checked the site no longer offered it. Searched for days trying to find the file elsewhere. No luck. Cant think of the company that made the driver.
I'm bumping this as I am also after the same sort of program / utility.
I want to be able to access my External HD and view / play files off it... anyone able to help me out?
Maybe with a external powersupplied disk

Correct
Our Hermes has no usb host support. I found a topic at forum.brighthand.com which suggested the host functionality could be added with a usb host driver. I found the software (attached zip) but alas... Though I did exactly as the 'manual' (readme.txt) explained, the usb-stick did not appear in my explorer.
Possibly an external drive with external power supply might work because the hermes usb port is simply not powerful enough to supply the power to the usb-stick. However I did not "explore that possibility" (don't have one ) and chances are 'just a driver' is not enough and hermes lacks "usb host hardware".
dident read the post because you dident give a link to the post just the forum
but i doubt that it's a general thing
many pda's have usbhost in the cpu itself but htc never connected those connectors
so it's not wired to the connector they have their own usb chip
so if the post you read said it about any other pda then htc based one it could be that that manufactor did connect the usb but dident supply the driver which would then be fixed with what you found

Sounds like there could be the potential for a hardware hack...
heh, nice try. but it will end like GPS HW hack on the TyTN (aka Hermes). it is not worth it, I mean there is easy way, just buy device with GPS integrated, or buy external. I have electronic skills and proper tools, I can do such things but it is too complicated. in that hermes was problem, that antena was not properly connected and you can never get a GPS lock. I guess that with usb host is the same. missing circuitry.

The USB host port of the Samsung CPU is used to connect to the internal GSM/GPRS chipset. So no chance to break it up!
If someone would ever hack this hardware part, the result would be a hermes without radio.
The engineers at HTC used the USB host port to achieve the necessary bandwith for high speed data connection to the GSM/GPRS chips from Qualcomm.

thats an interesting information, thanx

I cant find a pinout for the 16pin plug and was wondering where I can find it, but I dont think that would help me anyway.
I have a requirement for a Standard Serial port (RS232 type not USB).
Does anyone have any experience/advice on how to do this?
Do USB to serial adapters work?
Is there a mini SD to Serial port that anyone makes?
Any other ideas?
Thanks in advance
Jon
Have a look at something like this http://www.roalan.com/Bluetooth Wireless Serial RS232 Converter.htm you will have to code your own application for the phone to make use of it, I have used a similar device with my Athena - Mike
Thanks,
I am trying to avoid a wireless conection. What I am trying to do is use the Athena as a moving map for a glider. To do this I need to make use of an external GPS NMEA source. The software I am using works fine on a pda that has a std com port, I am hoping for a 'quick fix' to try it on the athena.
will this work, I havent looked for drivers yet tho!

I have to ask the obvious question though, why not use the internal GPS receiver in the phone? - if the application software you have isn't capable of switching the internal GPS on (some struggle with this) use Fransons GPS Gate to activate the inbuilt receiver and configure the ports, I would expect the inbuilt GPS to work quite well in a glider to be honest, and it does output NMEA data - what mapping application are you trying to use?
USB / RS232 converters are not the way forwards though, the mini USB port on the device is not a true USB port, it will not work with this sort of hardware, even if it did the converters generally don't work well as they don't use standard RS232 voltage levels - Mike
A good question. The external NMEA source contains additional sentances for things like accurate air speed and vertical speed that comes from a flight computer making measurements of the air. This is used for some of the calculations on the PDA. The software I will probably use is called SeeYou http://www.naviter.si/products/seeyou-mobile.php. There are several others, but this seems to work best in Landscape which is how I want it.
The internal GPS works fine with the software just to give map position.
I have managed to get it working by emulating a NMEA output over Bluetooth from a PC. I will try something like the Bluetooth to serial adapter and see what happens!

USE G1 As External GPS On Laptop - Can This Be Done
The reason why I am asking this is cause I am building A Car PC.
I can use the G1 as A Wifi Connection Surf The Net With Internet Explorer, Firefox, etc....
But It would be great to use with MS Streets Of Garmin PC, etc... with the Dreams GPS
If this has not been done yet it would be great if some one could (Must Likely a Developer) make a program that can do this
Thanks In Advance
And I Also Already Did This SEARCH FOR USE G1 As External GPS
im pretty sure this has been covered b4 but im not 100% and the answer then was no( i personaly dont know but i remember seeing a bunch of people saying no) well hopefully thats helps a lil..
maybe the dream uses a comport to communicate with the gps reciever, if that is true you may be able to redirect this to a bluetooth-comport
It may be possible, but I really don't think it would be worth the tremendous effort, considering GPS dongles can be had for less than 20 a pop.
I think it would be awesome to do since it's one less piece of equipment to carry around.
All it would take would be:
A program to take reading of the GPS info.
Convert it to the proper format (emulating a GPS dongle which isn't hard.)
There already are various programs that can send data to the PC. Use one of their code.
Have a program on the PC to translate it all into a virtual com port.
But then... I'm not a programmer. And the way I discribe it would be more like a hack than a proper program. But I don't believe the android API's allow you to control the way that the USB or the Bluetooth is identified by a computer.
It can be done but I don't think android naively supports the serial port profile over bluetooth which you would need to accomplish this. Once you figure that out all you need is to get your phone to spit out NMEA location data over that connection and your laptop will see it as a Generic GPS device.

Indeed, and if you're building a CarPC, a small GPS dongel - that can be placed in good line-of-sight - is the better option anyway.

I would prefer connection over internet or WiFi as it won't be easy to provide sky view to an laptop or pc so any user may place his laptop or pc at an place, get near an window for sky view to his android phone, then the data would be transferred to pc via internet or WiFi connection instead of connecting usb chord each time...
There are already apps like printer share which uses the phones internet connection for printing, also the upcomming app teradesk that lets an user to get files from his pc even when we are far from our pc,.....
Both apps use a server and client method for data transfer... so hope this would be possible...
