TOPIC - Wintec WBT-201 Data Logger
Bluetooth, uBlox Antaris 4, Photo Geocoding Software
The WBT-201, second from left
The Wintec WBT-201 follows in the steps of the Wintec WBT100/200 (reviewed here), the major change being the upgrade from the uNav chipset with average sensitivity and accuracy (at least with the Fastrax firmware) to the high sensitivity uBlox Anataris 4 chipset. Semsons were kind enough to send me a test unit and after two weeks of regular use I have put some thoughts together.Comments:
- Same exact form factor as the WBT-200, probably still the smallest BT GPS on the market, let alone with a logger
- I had trouble charging the battery that was compmletely flat, I had to put it in an old RBT-2001 GPS
- TimeMachine software offers a lot but takes some getting used to. The fact that the number of logged points does not refresh itself is a bit confusing at first
- The buttons are convenient and work as advertised, power/bluetooth and mark/new track. A stop log button would have been useful if you want to use it as Bluetooth GPS only
- No PocketPC software on the CD. I tried the G-Tool software of the WBT100 but it caused my PDA to crash :-(
- Tracking Sensitivity is rated at -158dBm rating, which seems consistent as it is pretty much on par with SiRFstarIII and MTK receivers
- Slow Warm TTFF (Time to first fix in the morning) in an environment with a low signal level (150 seconds on average, versus 50 for SS3, NX3 and MTK), probably due to the smaller patch antenna and possibly lower correlation power of the uBlox chipset
- I was happy to find it to be compatible with the uCenter Mobile software so maybe there will be a firmware upgrade to make it work with uBlox's offline AGPS AssistNow Offline
- Battery life is similar to the Wintec v1, a nice feat since the GPS Chipset is the more powerful uBlox Antaris 4 vs the uNav :
- Logging mode : 17.5 hours
- Bluetooth+Logging mode : 11 hours
- Pedestrian tracking shows more "wandering" than SS3 but dynamic enough to track progess at slow speeds
- Data transfer speed is fast and the software does some useful splitting based on on/off, but still allows for exporting as one GPX file
Final words/b] : the WBT-201 is an interesting upgrade from last year's WBT-100/200. The more powerful uBlox Antaris 4 chipset (A-GPS compatible, see above) gives some added tracking margin compared to the uNav and more accurate tracking at driving speeds. Pedestrian tracking is a bit "wobbly" compared to SiRFstarIII based systems, but dynamic enough to track progess at slow speeds. The wishlist would include a PocketPC application. With Wintec's history of regular updates, both to support software (PC and PPC) and GPS firmware, you can't go wrong if you need a sensitive Bluetooth logger. It is available at Semsons for $95 with 10% off for GpsPasSion Club members.
[b]Posted by pastorsoh : I just preordered Wintec's new version of WBT-200, WBT-201.
It looks like it is loaded with a different chipset.
Does anyone know of the new chipset?
You can find the info here;

Did you spot the new TimeMachineX software? Every logging combination under the sun and a bunch of new track download options with a nice 'insert picture for Google Earth option, you can finally adjust the annoying flashing LED frequency!, it shows the tracklog fill status without starting a download, password protection, auto sleep mode, auto track mark (waypoint?) based on speed to name but a few...
However, the Wintec website states "Not Support update firmware" for the WBT-201? Is it not ready or will never have this capability?
Download the TimeMachineX v1.11 software (25mb) and the manual is in the zip file with plenty of screenshots if you want to take a look...
ftp://customer:123456@mail1.wintec.com.tw/support_file/TimeMachineX.zip
I doubt this software will work with my WBT-100 which is a shame!, so can only hope we get a firmware and/or software update for the WBT100/200 sometime soon... come on WinTec you know you want to...
OB.

Yes, wonder whether it's the SuperSense or standard version though, likely SuperSense with the -158dBm rating. uBlox sent me a Socket Bluetooth GPS last year and while it was sensitive indeed, I found that it didn't track as accuratly as the MTK or SiRFstarIII chipsets, as can be seen here.
Looking forward to using the 201, a test model is on its way to me courtesy of Semsons ;-)
@obarnes - nice find, have you had a chance to try it with your WBT-100 ? |

I just tried to use WBT-100 with TimeMachine X – is not compatible. As these two units use different chipset the software is also different. So you cannot use WBT-100 with TimeMachine X and WBT-201 with G-Tools.
Oops. Update. I did not change the Baund Rate and left in in 9600. Also I did not noticed that there is a new G-Tool upgrade. Version 2.83 which suppose to give “Additional track transfer format----WBT201(G-Rays II (*.tk1)).”. Hm, let see.
Ok, there we go. I could connect WBT-201 to G-Tool. Have to change Baud Rate to 57600. Otherwise does not work. The satellite status maybe displayed. And now I’m getting to track points. Right now I have over 84 000 points (64% of capacity) on the WBT-201. Let see…. “Software can’t get the device name. Please, re-connect again.” Did it and still nothing. 
So, I cannot use G-Tools to download the track, but can convert the tracks from WBT-100 to the WBT-201 format.
Playing with WBT-201: now I have 130.969 log points (99% of capacity).

Did you get your eval unit yet? I'm VERY intrigued by this device, and am interested in your opinion.

| That’s right. Now can confirm without doubts that it has over 130.000 track points. If you have any questions do not hesitate I’ll help as much as I can. |

Does the WBT-201 work under linux? (the WBT-200 is supported via gpsbabel, but
as the WBT-201 has a different chipset, this is unlikely to work out-of-the-box,
I'd guess)
How accurately does the WBT-201 track when walking (do you maybe have an example)?
In addition I would be interested in a direct comparison to the Globalsat DG-100
in this respect.
(The long battery life and use of normal batteries still make the DG-100 more
interesting to me, but so far I was not able to buy this device from Germany)

I was wondering if it gives altitude too. And how about speed?
Any idea if the WBT-201 would work with Tom Tom Nav 6 running on a Treo 700p (Palm OS)? I presume I'd need to use a PC for the data logging functions, which is fine for my needs.
I'm also wondering about the speed and sensitivity of this new chipset. I've read (here on this forum) that prior models (WBT-100/200) were lacking compared to the sirfIII. Have they closed the gap? I have a Globalsat BT-338 w/sirfIII, and am just learning about data logging. Would hate to take a step backwards from sirfIII to gain the data logging.
Thanks for being hospitable to a newbie! |

Yes, it does give the altitude and also speed.
Hm, I was trying to add a screen shot from Google Earth with my track this morning, but cannot do it (where should I save the picture?). Any suggestions, please.
The software (TimeMachine X) which is coming with the unit supports only Windows XP. For PPC only with Windows Moblie. Up to now there is no software for Palm OS. But it does not mean it will not work with Palm or Linux.
Log Mode Settings:
• Possible to disable data logger
• Heading interval record mode
• Speed auto-change time interval record mode
• Time interval record mode
• Range interval record mode
• Mix Range-Time interval record mode
Also possible to mark a waypoint and divide the tracks without using any additional hardware. 
The first function (Heading interval record mode) works wonderfully. It may safe some tracks points and more important making the readings on Google Earth clearer as is not marking points while driving straight.
Personally I think it is nice piece of equipment for the price (at semsons sale price USD 94.99) |

It's cool that it includes altitude and speed!
I'm still trying to figure out if it will work with Palm OS. Semson's says the output is "Output Message : NMEA 0183 (GPRMC, GPGGA, GPGSA, GPGSV)"
The globalsat bt-338 (which clearly does work with PalmOS) reports out as "Output format: GGA(1sec), GSA(5sec), GSV(5sec), RMC(1sec),VTG(1sec)"
These look pretty similar, but I don't really know what I'm looking at.
Lastly, Semson's is offering a pre-order discount of $20, making it only $74.99!

I just noticed a little problem with the WBT-201's TimemachineX program.
I live in New York area, [GMT-5] zone and as you know starting from this year, the daylight savings time started two weeks earlier than usual and will end an hour later.
When I loaded the track info in TimemachineX, I see that the time code is incorrect for -5 zone. It's an hour ahead of the actual time. (2 pm rather than acutal 1 pm)
Is this the satelite problem or the program problem?

For your information, I am attaching a picture of TimemachineX generated google map image.
As you can see, the accuracy is not superb but acceptable.
I walked around the building taking pictures.

Thanks a lot for this interesting image.
Somehow there seem to be some larger jumps in the track,
but maybe that's the path you walked?
(If it's not too much effort, could you
draw, by hand on top of the image,
the path which you used?)
Does the track correspond to logging every second?
Thanks a lot, Arnd |
