Hello Henry,
One other update I can give you is that I did buy a Sandisk 2GB MicroSD card to see if it was any better. Unfortunately I didn't see any difference in the speed, and the program still responded as sluggishly as before, but only when the GPS driver was connected. Otherwise the program ran quite quickly. I also tried using that MemMaid 2 program to change the MicroSD cache to 256kb from the 64 kb default, and that did not seem to help either. It seems that option is only available for certain types of cards, such as the Sandisk SD/MicroSD cards, but even with it enabled the program lagged horrendously with the GPS driver enabled. I also tried with both FAT16 and FAT32 and unfortunately did not see any difference.
Thanks,
Peter

Subject: RE: TomTom 5/6 Very Slow on rx1950 with SDG-810
Hello Henry,
With the new driver I managed to get the device to 9600 and 4800, at those two settings TomTom would say that it was 'Waiting for valid GPS Signal' and also sometimes say 'No GPS Device.' I was not able to get a fix through the program on either of these settings and the program seemed to be very slow at some points, and normal at others. With 38400 though, I am able to get a signal. The way I connect through 38400 is to very quickly upon starting the program go to the GPS settings and turn it to some incorrect setting, such as 4800 with Spectec SDIO Driver, or Com 3 for instance. Then when the program is running normally I change it back to the correct 38400 baud setting, and the GPS Lock and data become visible in TomTom. Occasionally the program will even start to track my movement. The program is very slow, however, and whenever I try to do anything more, however, such as going through the menus to navigate somewhere the program becomes extremely sluggish and will take 1 or 2 minutes to respond to a keystroke. It also seems to freeze up for 5 minutes sometimes. It doesn't seem to get better until I eject the SDG-810 or do a soft reset of the device.
I tried your suggestion to improve the SD performance, including formatting the mini-sd card to FAT32. I attempted again to change the MicroSD Card Cache, but was unable to do so in MemMaid 2 as I was advised previously. How do you do the change on your rx1950 device? I have changed the firmware on my device to an older version to try to fix the problem, and the SD is faster now with this other version, but it doesn't seem to help much in TomTom when using the SDG-810.
Please see my reply at - THIS POST - I am the pjpeter in that post, I sent that out at about the same time I first contacted you last week.
Thanks,
Peter

Dear Peter,
Here are 2 steps to improve SDG-810 performance:
1. I formated the SD card in FAT32 (it was in FAT16);
2. Then, increased the size of the MicroSD card cache. I mean, the OS reads the data in the card in 16kbytes chunks by default,
and please increased it to 256kbytes.
Please try it, and let me know the result.

Dear Peter,
Please have a try on the new SDG-810 driver by a lower baud rate (like 9600),
and see if the same observations come.

Hello Henry,
One other quick update, I was able to get the TomTom software to eventually update the status when the GPS unit had a lock so that it would display the correct Latitude and Longitude and knew where I was on the map (as it would do before). However, while connected the program was as sluggish as before taking 1 or 2 minutes to respond to any command, and it continues to show 'No GPS Device' rather than 'Connection Lost' or some other message as it should give when the device (the SDG-810) is still in the PDA. Even after exiting the TomTom GPS status screen it continues to act sluggishly, whether the SDG-810 is blinking or not, taking up to 5 minutes or more to respond to a screen tap.
Thanks,
Peter

Hello Henry,
Thanks for sending this along to me. Here are the steps I followed:
I installed the sdg810_1204_p.cab file you sent me, expecting that it would ask to replace the SPECTEC GPS Driver already installed, but it did not. So after getting the same response as previously from the applications I uninstalled the old Spectec driver. Then when I reconnected the card I got an 'Unrecognized card' message so I reinstalled the driver. After this I was getting slighly more speedy response from TomTom except when I clicked to go to 'GPS Status' when it would freeze for a minute, and then resume when the screen was entered. But there was no GPS info there and it continues to say 'No GPS device'
I realized that the Aurea SDUART driver from the website was also installed (the standard driver, I had installed it as well as the rx1950 specific one to see if it helped me connect, which it did not). I uninstalled this and once again got the 'Unrecognized card' message on reconnecting my SDG-810 so I reinstalled the new driver you gave me and I was then able to access GPS as before with Mapopolis and GPS Viewer. Once opening TomTom and setting it to the new SpecTec SDIO Driver though it would still would not say anything but 'No GPS device' so I uninstalled the program and did a Soft Reset. Other programs still work, but TomTom won't connect and it still reacts sluggishly in the menus after the GPS is selected (and all other times the program is opened after that point, since it remembers it), even right after a soft reset without opening any other programs. As soon as I eject the SDG-810 from the SD card slot though, the prorgam instantly starts to respond. I haven't been able to get it to find my location with this driver though.
Is this expected behaviour with this test driver? Should I follow some other steps or do a hard reset?
Thanks,
Peter

Subject: RE: TomTom 5/6 Very Slow on rx1950 with SDG-810
Hello Henry,
Thank you for replying. I have not contacted you previously, but I have read over the SpecTec discussion forums and i have a problem similar to what Russia wrote on the forum, but did not seem to get a reply to there:
http://www.spectec-dot-com-.tw/cutef...sp?main_id=129
"Hello.
I alsi have HP 1950 and sdg-810 devices.
Initially it was very slow (in a tom tom searching of a city requre 20-30 secomnd for each letter), and now it almost not connecting to satellites...
How to fix this? "
I had a similar experience with TomTom 5.21 and TomTom 6.75. In both cases the programs worked very fast with the micro-sd and Spectec SDG810 installed in it, but with the GPS not setup. But once I set it to NMEA-38400baud-Com4 "Spectec GPS Driver" the program would almost instantly go very very slowly. I found that if I ejected the SD card things on the screen would refresh and the program would show my current location, but then a few seconds later it would go back to 'No GPS Found' and when I reconnected the card again the program would be just as slow. The status does not refresh often if at all and it often hangs once the driver is selected. It was as if it was getting all the GPS data and couldn't sort through it until it stopped, maybe it was getting it too fast or it was doing the wrong thing with it or something. The pda would get very hot, as though in some sort of infinite loop maybe, or doing processes without being able to accomplish anything. I also tried with Wififofum which is a free program for finding Wifi signals and triangulating them with GPS and it would also crash/go very very slowly with the rx1950 and SDG-810 as soon as I enabled the GPS and set it properly to the SDG810 port.
I found that Mapopolis did work, though it is a very old program which is no longer supported and has maps 2 years out of date.
I am using my Spectec SDG810 with a Kingston 2GB micro-SD card. The driver I am using is modified SpecTec drivers for the rx1950 and a few other PDAs from the website, "HTC Charmer PM200, Qtek S200, HP 5965, HP 1950, HP 2190, Dopod 900, ASUS p535, Treo750, DELL x30, TOSHIBA 1830."
I have tried doing two hard resets and just installing the SDG-810 driver (and general-sdio.cab driver so I can access the micro-sd card) and the TomTom software without any boost in performance.
I tried with GPS Tweak and GPS Finder and confirmed that Com4, 38400 is correct and they do show lots of GPS words when turned on and GPS Finder is able to lock onto Satellites. It's the big programs such as TomTom using the micro-sd memory to access maps which seem to have problems, or which the programs which run off of the card. Maybe it could be something to do with the gps data from the driver overwhelming the data coming from the micro-sd? I'm not sure what else to do, I'm hoping maybe you know amd maybe even you helped someone in the past with the same sort of problem so it would be easy for you.
Thanks very much,
Peter

Subject: TomTom 5/6 Very Slow on rx1950 with SDG-810
Hello,
I've had a lot of problems trying to get the SDG-810 to work sucessfully with the rx1950 using WM5 and TomTom 5 and 6 for about a month now with no luck. I am able to use the GPS but it is very slow and the device crashes often. It does work ok with other software such as Mapopolis, but this is old and does not have new maps. I am willing to help if i can and will test drivers for you if that helps.
Thanks,
Peter
