IPAQ 5720 and satellite lag on memory map

Just bought an IPAQ 5720 which is great but......

The device comes with tomtom 6 which works well.

I have loaded my old version of memory map v 4.4.3

The memory map gps position lagged so I fired up MMSiRF and all was well - but only for a couple of minutes. I reran MMSIRF again all was well but not for long!

MMSIRFsetup is port 1 and baudrate 9600

I guess some other program is resetting tje gps. W4e were not running tomtom at this time.

 

Any ideas?

I have run MMSIRFSETUP and the memory map position updates on time but for less than a minute.

Are there any other setup options or chnages I should make?

Could it be that everyone else uses a later version of memory map?

Dunno if this helps but my Ipaq 5720 uses port 7 I am running MM5 though, but I would have thought the ports would be the same ?

 

There is a sirf tutorial HERE that might be worth a look :rolleyes:

To expand on that, my 5720 has the following GPS settings:

In the Programs tab the port is set to COM7

In the Hardware tab the port is COM1 at 9600 baud

In the Access tab the box is ticked to "Manage GPS automatically".

That all works for me - but I have not tried to use TomTom and MM at the same time.

Thanks for all the help you good people but I am not there yet!

 

I exit tomtom and memory map using the exit command rather than the red X! Have also checked all ports and they are as suggested.

 

Just experimented with memory map after a hardware reset ie tomtom has not been run.

Placed the GPS on display location and I could see the time lag from when I changed direction. This was after setting MMSIRFSETUP.

 

I am now wondering if it is because I am using an old copy of memory map - version 4.3.3. Does anybody else run this version of MM?

I downloaded MMsirfsetup in to the Mio and tried it out on Monday but MM v4.3.3 was still lagging behind and while walking towards a cache I was having a little play with the settings in MMsirfsetup but all it did was freeze the PDA, tried again yesterday after first making sure no other programmes were running and managed to set up MMsirfsetup, I originally set the com port to the same one as MM but found this didn't work and changed it to the GPS programme port setting and it now works perfectly.

 

Thanks all.

Looks like Des is working fine but I am still struggling.

To I am running MM 4.4.3 and my settings are :

Settings menu

GPS program port 7

GPS hardware port 1 9600 baud

Manage gps automatically

 

MM

Type NMEA (but there is an option for SIRF)

Port com 7

Baud 4800

Disable power off

 

SIRFSETUP com1 9600

Attempted to set up with com 7 as suggested by Snerdbe but program just hangs

I am running MM 5.1.3 and have the MM baud rate set to 38400 - all other settings are the same.
