Just wondering if anyone is using this. It ticks all the boxes for me and seemed easy to set up but, despite having it running, I don’t think I’ve got it right. The translation is a little confusing at times I think.

…and my knowledge is very patchy.

Hello,

Here for y base, I have :

NeoM8T
Rpi Zero W
NeoM8T is connected via USB to Rpi, Rpi is powered by standard 5 V AC-DC
Rpi runs strsvr and transmit to my box via wifi and then to rtk2go
If this this could helps you …

Thanks. So many options for this sort of thing.

One reason for using RPINtripBase is that it produces the 1008 message required by some trimble receivers.

Output from /usr/bin/socat TCP:localhost:2102 - is very garbled, much like baud a rate issue. Not sure where I am wrong.

Is possible to us m8t as base? Where did you find the instructions? I have f9p which I use with public NTRIP caster, but when I started to build my setup I used m8t and rtklib. Could you share a guide to properly setup a base with m8t and a raspberry? Thank you

This is the software I am trying to use. I think it it working fine. Just not got my internet set up properly.

# RpiNtripBase

Dies ist eine einfach zu konfigurierende RTK-Basisstation für Linux. Verschiedene GPS-Empfänger können angeschlossen werden,
normalerweise über USB, direkt an der seriellen Schnittstellen geht aber auch.

# Attention
**Please don't fork the repository, if you're not planning to do any changes to the source to send back as Pull Request. There is a button with a star on the page header, besides that is the button to watch for updates. Both help you keep track of the repositories you like.**

Forking makes it extremely hard to keep track of the improvements upstream, where a simple clone is updated in seconds. There's no sense in running an out of date version.

# Achtung
**Bitte forkt das Repository nicht, wenn ihr nicht vorhabt, Änderungen daran zu machen, welche ihr mir als Pull Request wieder zurückschickt. Ein Fork aktuell zu halten, ist kompliziert und zeitraubend. Es gibt extra zwei Köpfe in der Kopfzeile, wo man das Repository merken und beobachten kann.**

# Features
* NTRIP Caster auf Port 2101
* Proxy für die serielle Schnittstelle auf dem Port 2102; die Basis kann auch nach der 
  Installation mit dem uCenter konfiguriert und geupdatet werden
* Alles über systemd-services geregelt; werden automatisch gestartet, haben in eingebautes logging und starten sich bei Absturz selber neu
* Baudrate einfach änderbar
* Läuft grundsätzlich überall, wo ein Linux läuft, `systemd` verwendet wird und man `root`-Zugriff hat.

Hello,

Here are for the big lines :
For the M8T

set RAWX and SFRBX on the USB (1Hz ?) speed 115200
For the Rpi 0 W
download rapsbian
start in headless (I’ve no micro hdmi adapter)
add the 2 files with ssid and pwd for enable the rpi on your box via wifi
Download on Rpi (I use Win32DiskImager)
at this point, you can log on the rpi with ssh, (personaly, I use moba xterm)
set to fixed IP address on wlan0
download and put rtklib 2.4.3 on the rpi
compile str2str on the rpi (make in the directory there is makefile)
add the following command in the crontab (it’s better than to put it in /etc/rc.local, it restarts automatiquely)
This is the best I’ve found (pwd and ip are the rtk2go login)
** * * * pidof str2str > /dev/null || /home/pi/RTKLIB-rtklib_2.4.3/app/str2str/gcc/str2str -in serial://ttyACM0:115200:8:n:1:off#ubx -out ntrips://:pwd@ip:2101/FRA_62160 > /$
For me it works, you can test at FRA_62160 (in binary ubx format, but I think it could be configured as a RTCM output format with str2str, I’ll see that later …)
Best regards
