Hello!

Do you have some news for this GPS issue?

I have a v12 GPS MTK version too and I don't succeed in logging my gps to the IMU. Blue led stops blinking on the GPS but the IMU red Led always blinks ... Can you help me please. I didn't flash my GPS.

Thanks

Was this issue resolved? I'm getting 0 sats, 0 Fix, 0 HDOP but what looks like valid Long/Lat data even after an hour or so with APMega 1.02. I have alreday updated the GPS firmware, reset the IMU and have a GPS with battery.

You probably have the new firmware. Select GPS_PROTOCAL_MTK16. If that doesn't work, please wait a day or two and will release new software that supports it.
