MediaTeK update rate resitricted to 4Hz. How to make it to 10Hz

Posted by Qian Zhengyin on June 10, 2012 at 8:58pm

Hi, All

I am currently using MediaTeK (firmware 1.4) and ArduIMU version 3.0 together for my UAV project. Everything works well except that the GPS update rate is only 4Hz. Can I ask how could I update it to 10 Hz?

Is it got anything to do with the GPS firmware version? But I seems can't receive anything with a v1.6 firmware GPS...

Thanks and any help is appreciated!

I think the binary protocol changed over the FW versions. I think it is a different preamble (sync word) and the byteorder is reversed (the 4 bytes of lat/lon etc are now incoming from low to high byte).

So long
