Permanent setup of Mediatek 3329 GPS needed...

[quadflyer8]

Hello,

I search a way to permanently write settings into the Meditek 3329. Have successfully flashed 10Hz / 115200 Baud firmware and my Kopter is flying ok for GPS PH or CH, but I want to set it permanently to 5Hz and using DGPS for a more precise Position. In 10 Hz Mode no DGPS is possible.
I used MiniGPS or MtkDLut for changing settings in GPS Module, this works, but setting is lost after several time and sets back to 10 Hz / 115200...

The question is:
- Is there a programm for a permanently setup ofthe GPS?
- is there a firmware for Mediatek 3329 that setups 5Hz / 38400 and DGPS on permanently (as the 10Hz / 115200 Firmware does)
- if not, we have to send a init String to get it to the desired setting at each start...at the moment I can't find a place in the Code where a initstring could be placed...

shift+s or ctrl+s in MiniGPS saves settings to eeprom - not sure of the exact key combo - RTM

I have the SKYLAB SKM53 w/ the MTK3339. I make the changes in MiniGPS but after 10-12 hours it is back to default. I tried to flash with powerflash but get a syn error and cannot seem to get around it. I found some code to init the unit but, it compiles to big for a 328. Anyone know how to get around the sync error in powerflash?

CTRL + ALT + S

i dont think saving that was is supported with some of these modules

MTK 3329 can be updated with new firmware with 38400 5Hz defaults or 115200 baud 10Hz.

Thanks to Eos_Bandi, we can download all the tools needed from here:

..i agree BUT line 1176 of I2C_GPS_NAV.ino begins with the following comment:

Code: Select all

#if defined(MTK)
/* Using the AXN 1.51 firmware which defaults at 1Hz/38400 but supports binary protocol
 * First connect to it with 38400, then set the speed to 115200 
 * and set the update rate to 10Hz
 * and finally switch to Binary mode
 */

first of all AXN 1.51 does not default to 1hz/38400, but 5hz/38400!!
then it sets the speed at 115200 and update rate at 10hz which is too much for MTK.

iam confused once again..

im not sure either... maybe changing it with serial commands if cant be saved. ill try that new firmware

also btw in another thread eos advises to run this module at 5hz in binary (he didnt think it support 10hz)
