You know what? I'm not even surprised anymore. Whenever the 0.01% of the shareholders of everything gets hold of something, It declines. You replace your washing machine that lived a 20 years, The new one only goes 8. Same with the raspi, at least the OS sucks. Everything is different and on an other place. Ghhhhh. This thing is designed for children to learn microprocessors. I'm happy I'm not a child. Still not succeeded in getting a static ip.  |

Did not suceed with the Noops Buster. Several startupjobs taking ages, and it was a very enerving experience. So I tried OPENPLOTTER. Burned the image started up and ready. It is a buster with OpenCpn and a wifiacces point and a lot of things. But it starts up very rapidly. Next stop is finding the AIS port.  |

Hi Rik
making headway , good news
At present still muching around , thought would test the gps against gpsfake
these are the results
part of printout using
gpsfake -p -i gpsdata.txt
and the results of
./gps2 '$GPGGA,081850,3702.2023,N,03522.4668,E,1,07,1.2,62.2,M,29.7,M,,*77'
$GPGGA,081850,3702.2023,N,03522.4668,E,1,07,1.2,62.2,M,29.7,M,,*77

so looking further at the decimal places & print format
PS : Are the windows any better

Got it connected on /dev/ttyUSB0 baudrate 38400  So now get some charts. Incredibly how quick this Buster goes. I must have done something realy wrong in my previous attempts. Unfortunately, and to my astonishment BaCon is not pre installed.  Well, I'll leave it that way. Let's not meddle with this OS too much. BaCon executables compiled on the RPi3 seems to work, so I have this: ./gps2 '$GPRMC,023044,A,3907.3840,N,12102.4692,W,0.0,156.1,131102,15.3,E,A*37'Gives me: Talker ID: GP

I have no idea how to connect my gpsd to your gps2 however. What windows?  Rik. |

as regards Serial port read I have not implimented on pi4 till now Please refer to basic-converter.proboards.com/thread/175/serial-port-accessno need to Install the lib , use the .h and .c files as below as test here using gpsd test suit . not good at getting all results since access will block on a read , it is noted the files , but there is a time out funtion which should resolve this issue [b]cssl_settimeout[/b]but it does work, I think says he. bit from the terminal pi@raspberrypi:~/Downloads/libcssl-0.9.2 $ ./test2

maybe this will also work ' /dev/pts/2",(void*)callback,0,4800,8,0,1)

I think though that if you query your AIS/GPS then other applications can not query at the same time(?) As I have now understood, they have solved this in OpenPlotter with a server that polls the info and then gives it for all applications to use. It's called: Signal K(But I'm not so far yet, still using /dev/ttyUSB0) |

have not managed to get anything from the serial device yet, so looking further
as a quicky
This works
from the socat
pi@raspberrypi:~ $ socat -d -d pty,raw,echo=0 pty,raw,echo=0
2021/03/06 00:50:30 socat[28620] N PTY is /dev/pts/3
2021/03/06 00:50:30 socat[28620] N PTY is /dev/pts/4
2021/03/06 00:50:30 socat[28620] N starting data transfer loop with FDs [5,5] and [7,7]
and the
bacon code
OPEN "/dev/pts/3" FOR READING AS myfile
WHILE 1 DO
READLN txt$ FROM myfile
IF LEN(txt$) THEN
PRINT txt$
END IF
WEND
CLOSE FILE myfile
from the third terminal
pi@raspberrypi:~ $ echo "Test" > /dev/pts/4
pi@raspberrypi:~ $ echo '$GPGGA,081850,3702.2023,N,03522.4668,E,1,07,1.2,62.2,M,29.7,M,,*77' > /dev/pts/4
and from 2nd bacon terminal
pi@raspberrypi:~/bacon $ ./serial
Test
$GPGGA,081850,3702.2023,N,03522.4668,E,1,07,1.2,62.2,M,29.7,M,,*77
at end of day, will probably need the timeout and callback functions in the mentioned lib
as regards K signal , as soon as I see J then I want to run a mile
as Vovchik once said
'Why use a Howitzer when a peashooter will do'
+ I am looking at the exchange format 'JSON' that can be done with gpsd
as a side note and in short I broke the PI4 sd card, and had to get a new one
BR
Alex
Forgot to mention If have permission problems on tty's serial like /dev/ttyUSB0 with bacon (OPEN "/dev/pts/3" FOR READING AS myfile)
try adding the bit to dialout
If wanting to access different devices at the same time
look at the BaCon Web site and look for 'INCLUDE: POSIX Threads' + examples
more on that one later.

Agh Well
need to dig deeper
getting garbage from the real I am with bacon open file as normal on ttyUSB0
here is a sample from my ais gps

in there is AIS noted from '!'
also GPS noted from '$'
now going to download the necessary, as mentioned working with new install , for what it is worth , gpsd does not recognize the device
well up to now,
if can make udev rule from the lsusb -v command , it may be possible that the gpsd will connect , ie configure in gpsd.socket

I think that means that you have to change your baudrate.  |

Hi All
as part of this thread I will be using maps
For SeaMaps
go to the openseamp the free nautical charst . go to downloads and select the area
click on the downloads select format : mbtiles . note the size IE ensure esp on rpi there is enough disk space
for the download conversion . if 1.5gb = 1.5 *3 , can recover space by deleting the mbtiles after conversion
for conversion use mb-util its a python script . and need to convert to png
example
cd Downloads
git clone https://github.com/mapbox/mbutil.git
cd to the mbutil
command
mb-util --image_format png /pathto/*.mbtiles seamaps
in my case
mb-util --image_format png /home/pi/Downloads/OSM-OpenCPN2-NorthSea-20201106-2207.mbtiles seamaps
in there will be there will be the png files + a json file . leave as is.
if not want seamaps , will be posting details of the bacon tile server for openstreetmap later
