Multiwii 2.4 GPS not working

[joergw]

Good Morning.

I have the following problem. prior upgrading to Multiwii 2.4 my GPS was working fine. After changing to 2.4, GPS will not find any satelites. Changed the config.h to the settings of 2.3 as follows:

#define GPS_SERIAL 2
#define GPS_BAUD 57600
#define UBLOX

//#define MTK_BINARY16
//#define MTK_BINARY19

#define INIT_MTK_GPS

//#define I2C_GPS
// If your I2C GPS board has Sonar support enabled
//#define I2C_GPS_SONAR

#define GPS_LED_INDICATOR
#define USE_MSP_WP

Any help?

I also tried to change the serial from 3 to 2, in the config.h and the connection to the board. Still no fix...

using Crius AIO Pro, UBLOX-6M, Bluetooth..

Thx in advance,

cheers, Jörg.

Having both #define UBLOX and #define INIT_MTK_GPS does not look right.

Hi . Tried also without init_mtk and worked with 2.3 so i left it unchanged. But will try again ...

Have now uncommemted the Init_MTK_GPS and it worked for about a minute. Then it lost all satelites again. I guess it is a hardware issue ...

Found the Problem. Have now GPS Signal and this inside the room...
It is the bluetooth. When i disconnect it everything works as designed. Now i have to figure out what is wrong ...
Any ideas ?

Cheers, Jörg

It's working. Used a different GND connection for the bluetooth and i have GPS and Bluetooth... now i need a new Prop and then lets fly ...

Cheers, Jörg .
