Berrygps-imu v3 not getting a primary fix

[fox6288]

I am a complete noob to this…

I have connected and installed all appropriate software and have an external antenna.  The switch is on ‘ext’.  When I try to use cat, screen, or minicom, there is no response. None.  Just a cursor in the case of screen and a new blank window in the case of cat.  I have let it sit for a couple of hours at the longest and am baffled.  I am also by a window with nothing blocking the sky except the glass.

Any help would be great. 🙂

Hi

You are not seeing any output when using minicom?

Can you  show me the output of this command

dmesg | grep tty

And what happens if you kill GPSD using this;
sudo killall gpsd
and then try minicom again
minicom -b 9600 -o -D /dev/serial0

you should be able to just copy the text from the terminal window. select it and the Ctrl-C.

 

what is the output after doing this;
sudo killall gpsd
and then try minicom again
minicom -b 9600 -o -D /dev/serial0

and when I do the ‘sudo killall’ it says it can’t do that, so I try and restart minicom and I get a blank box. Then I scrolled down a bit and it showed this.

you need to solder the headers onto the PCB

even if they are making contact? I wanted to make sure it was running properly before I made that sort of a commitment. lol

[fox6288]

I soldered it.  Now this is the message I am getting.  Is this correct?

Mmmm.. show me an image after how you soldered it

Ok.  Worst soldering job ever, but it’s a big soldering iron.

yes.. i can see that the pins are not soldered completely. You need to try and get it properly soldered.

I restarted the pi and double checked the solder points, its scrolling now like something out of the Matrix, but it looks just like the photos that have been provided.  I will continue to go down this path and let you know the result. 🙂
