There is an icon just below the menus that looks like an equals sign turned on its side. Click on that and watch it. If it flashes red every second, that means you are getting data. The next thing is to find out what. Ensure the following windows are open: Signal View, Map View, Radar View, Geodetic Nav View, Debug View, Response View and Error View. If windows are flashing, there should be something in at least one of those windows. Error View if baud rate is mismatched, Debug View if output is NMEA, and elsewhere if output is Binary. Anything?

One clarification: that icon I had you click on, the one that looks like an equals sign turned sideways, blocks screen updates. Once you see it flashing red, you know data is coming in. But you need to click it again to get the screen to update.

now it is getting "better", I guess the connection between bluetooth adapter and gps is fake. After reinstall my BT usb driver, the notebook does find gps but can not start service...
So SirfDemo can change the baud that comunicate with BT usb adapter?
is there a reset button on Slim236? I may open the small box and uncharge the backup battery...:(
thanks |

Hi, in the geodetic nav view window:
Map Datum: HDOP
COG: Hdg Error
Clk Bias: Error
Clk Drft: Error
Traveled: Error
others are blank...:(
also I saw GPS bluetoot light blink abnormally. for Slim236 it should be 3s a time if connected, right? Mine like 3 time long, and 4 time short... |

I got reply from Holux, they said I can use "CE Monitor utility " to reset the manufactory setting. They also sent me a link, which after download, I found it is winfast! So what should I do?
thanks |

Unfortunately I don't know the Holux details. My suggestion: pull out the battery and let it go back to factory defaults. And a warning to everyone: if you try to use the SiRFDemo feature "Synchronize Protocol and Baud Rate" it will tell your receiver to go to 57600 SiRF binary protocol. If you have a BT receiver like this one, where the BT modem only handles 38400, you just sent the receiver to never-never land! Unless you can directly connect to the serial port inside the receiver box, you have lost contact with it and battery removal is the only cure I know.

Thanks Carl.
I am gonna buy a bloody usb data cable with next day shipping, just in case I want to do expirment with it in the future :(
so how long do I have to let it set to completely dead? like 12+ days? do I have to pull out the battery? or just leave it there and let the power button on?
Or maybe I can open the box and discharge the backup battery(is there any?) Do you have a chart to show me how to open the Holux slim 236?
thanks |

In my experience, though not with this unit, leaving the battery out overnight should do it. On some units an hour is enough. Carl works for SiRF, and is here just to help out on technical issues, so he is not the one to ask about questions regarding individual units. That is out of topic here.
You might want to post your question over in the forum that is discussing the 236 and get some input from people who are actually using the unit.

Hi, I am new to the GPS world. I have a GlobalSat BT-338. I downloaded the SiRF demo 3.61 here and installed on my PC. I followed instructions and was able to connected to the GPS and browsed through the settings. However, when I switched from SiRF protocol back to NMEA protocol, it had a NMEA setup pop-up window with a set of values showed up. e.g. GLL, ...
Do I take the presented value and click "send"? I do not want to alter the factory setting but since I do not know what was the factory setting, I have nothinf to compare with. If the presented values are not the factory setting, how can I get them back? |

You can get them back by sending a factory reset command, the values by default are actually ok, the numbers represent the frequency of the messages.
Catching up with the activity in this thread !
1. I believe version 3.61 used the 38,400 baudrate when switching to SiRF, more recent ones use 57,600 for some reason, and that is inconvenient for use with most BT GPS receivers.
2. The good news though is that manufacturers don't let you change the baudrate of the GPS module independently from the BT module anymore, that happened with the Emact v1 prototype, Globalsat BT-308 and Holux 230 v1, but that was indeed a mess (neverland indeed) as there was no way to communicate with the GPS module anymore. From what I've seen since while a command may make you lose communication temporarily when switching protocol and baudrate at the same time, you can't desynch the BT and GPS modules anyore. If a receiver does not accept the SiRFdemo switch to SiRF the solution is to first swith to 38,400 or 57,600 with CE Monitor (Winfast) or spgps in NMEA and then connect via SiRFdemo at 38,400 or 57,600. You can also try connecting directly at the proper baudrat from SiRFdemo (i.e. 38,400 or 57,600, not 4,800)

| Is there any advantage using Static Navigation on SIRF IIe/LP chips, or is it almost the same with SN disabled? |

Won't change much as IIe/LP chips unlike SS3 chips don't work with the very low signal that can cause the "jumping" that SN tries to smooth out.

Biggest advantage to using SN is in automotive applications with map displays. These are often configured to show current heading at the top of the screen. Without SN enabled, such a display will often jump and spin while a vehicle is stationary at a stop light in urban environments. That was why the feature was first developed. For someone using a receiver in pedestrian mode, or even on a boat, I would never recommend it.

Ok. Thanks for the answers. I asked this beacause I have two Haicom HI-303MMF with me. One made in 2002 with SN disabled by default. The other one made in 2004 with SN enabled by default. This SN only ignores speeds under 3Km/h. Both receivers use the same chipset.
As the heading in automotive applications doesn't bother me much and I like to hike with the GPS sometimes I think I'll stick around with the older one.
Thanks for helping me choose. |
