gpsinit can't seem to set port baud rate correctly on RPi Jessie #5

gpsinit -s 115200 -f /etc/gpsinit_nav.conf /dev/gps0
Making sure the unit is in NMEA mode
Making sure the speeds match
The GPS speed and the port speed couldn't be synchronized.
Retrying
Making sure the speeds match
The GPS speed and the port speed couldn't be synchronized.

stty -F /dev/gps0 --all speed 115200 baud; rows 0; columns 0; line = 0;

Doesn't result in readable data from port.

stty -F /dev/gps0 9600 resets tty to 9600, which is what the GPS unit is at.

Seemed to work of wheezy.

Ah, stand-by. More testing indicates the chip isn't receiving ANY commands. If true, this would be why the chip didn't change speeds. Investigating.

Never mind. :-(. Bad HAT. I won't reveal how it was damaged.

I seem to have a similar/the same issue - could you share how you confirmed that it was broken without revealing "why" it was damaged :-) @K6TD ?

Sure...I replaced the HAT and all worked just fine. I don't recall how I damaged the HAT, now. That was over a year ago. I did damage it electrically. I think I either installed it mis-aligned, or some other mistake like that.
