MediaTek 3329 weird baud rate

Posted by Jose Olcese on January 17, 2011 at 7:02am

Hi,

I just bought a GPS module and it was working correctly at 38400 bps. After some power cycles I wasn't able to get more NMEA sentences from and instead I was getting some garbage.

I hooked a scope and realize the bit time which corresponds to 24400 bps. I switched baurate on mu PC to 24400 bps and I can get NMEA sentences however I can't change baudrate any longer. Even powering it off keeps the 24400 baud rate.

Tried to flash the firmware but flash tool does not recognize the module (I assume because of the wrong speed)

Any ideas?

Thanks

Jose
