  NMEA 0183 interface questions
Posted by: baltika_no_9 - 09-06-2016, 10:27 AM - Forum: General discussion - Replies (2)

Hello all

I'm in the early stages with setting up OpenPlotter. I've established connection with the AIS transponder by creating an input serial port descriptor on the NMEA 0183 tab. AIS contacts and boat's position now display happily on the OpenCPN chart - great so far.

I now need to extend that to incorporate other devices (wind/depth/autopilot etc). I plan to use the USB<>RS422 converter (or similar, the instruments are Seatalk) for this. My question is:

Is it possible to "drive" an autopilot from OpenCPN/OpenPlotter, say to direct it to change course?

Thank you very much

  SMS and Internet simultaneously with GSM Stick?
Posted by: Alpenskipper - 09-05-2016, 04:35 PM - Forum: How do I...? - No Replies

Is it possible to send SMS and use the internet with a GSM stick at the same time?
When my Huawei 169 Stick has an internet connection, I can't send SMS and vice versa.

Or is it a configuratiin error?


  ? EMail reports blocked by Google
Posted by: Alpenskipper - 09-05-2016, 01:28 PM - Forum: Bug Reports - No Replies


Since yesterday, I cant't send reports from OP via Google.

I got a notice from Google, that s unknown App was blocked. I unblocked the App via the Google account settings, but still I cant't send reports.
When I use Googlemail via a browser on the same Pi, it works.

Any ideas?


  RPi 3 in a metal Case
Posted by: warrenden - 09-05-2016, 09:22 AM - Forum: General discussion - Replies (6)

There are some very nice metal cases which make the RPi look like a “proper” bit of kit worthy of being added to your boat's nav equipment.

Unfortunately they would kill the internal wifi of an RPi 3.

You could fix this by adding an external dongle as you would have done for previous Pis.  But then you’d have 2 wifis operative.

Has anyone tried unscrambling the resulting confusion?  Is it possible in OpenPlotter?

Thanks for comment,


  Manage wifi network settings in /etc/network/interfaces
Posted by: jossie67 - 08-31-2016, 04:13 PM - Forum: How do I...? - Replies (1)

I have multible wifi networks .
So I want to manage the settings in /etc/wpa_supplicant/wpa_supplicant.conf
And config the network adaptors in /etc/network/interfaces.

But when I modify /etc/network/interfaces, after a reboot boot all the modifications are gone.

How can I solve this?

  How to get IMU data in correct format in OpenCPN?
Posted by: Ewald Harmsen - 08-30-2016, 02:40 PM - Forum: How do I...? - Replies (3)

I have connected a IMU + Pressure sensor to my RPI, it is working fine but...

The data is outputted as for instance "$OSXDR,A,33.3,D,I2CX,A,-2.7,D,I2CY*48"

According to this page "I2CX" should be "Barometer", "TempAir", "PTCH", "ROLL" or "ENV_WATER_T"

As of now the data is not recognised by OpenCpn. How have others dealed with this issue?

Photo Waypoints from InavX to autopilot
Posted by: hironimus - 08-27-2016, 02:59 PM - Forum: How do I...? - No Replies

Hi guys, first my equipment: Ipad with InavX navigation, raspi 3, a usb connected nmea-seatalk bridge (translates all seatalk1 data to nmea183 and viceversa) and running OP 0.8.0. With this constellation i get all nav data from connected Raymarine StT60 instruments on my ipad/inavx. But i could not find a way to send the waypoint data to OP respectively to the ST60 autopilot via usb / nmea bridge. Send data via second tcp adress or different port like in the other thread with opencpn is not possible, see below screenshot from inavx. The yellow lines are the via TCP sended waypoints from InavX. Hoping you have a solution, best regards     

  No touch on official 7" Touchdisplay
Posted by: Jan - 08-25-2016, 01:58 PM - Forum: Bug Reports - Replies (16)


i have the problem, that i can not use the touchscreen to control OpenCpn. To control the "normal" raspbbery pi system the touchscreen works fine. Only in the OpenCpn program i can not use it.
When i tap on the menue items in OpenCpn nothing happens. With an external mouse everything works fine.
I tried to install OpenCpn on an Raspbian installation, all works fine there.

Any idea?

  Connecting a GME AIS to RPi
Posted by: Tacmed - 08-24-2016, 07:46 AM - Forum: General discussion - Replies (5)

After connecting the usb lead on a GME AIS transponder to the raspberry Pi3 I noticed the lights would light up on the AIS as soon as i put power onto the Pi.
This will damage the AIS unit if left like that.

GME sugested i buy a isolation unit for the usb port.
They also advised that blowing up USB ports is commin when powering up a laptop with mains adaptor connected.

Anyway, I was wondering if anyone has one of these AIS units and has cut the 5volt line comming out of the Pi to fix thier own problem.

Wink openplotter_rpi_v0.8.0.noobs.zip
Posted by: pscheepe - 08-19-2016, 02:57 PM - Forum: Bug Reports - Replies (1)

I'm new to Openplotter but not to the Raspberry Pi.
I downloaded openplotter_rpi_v0.8.0.noobs.zip, extracted the files on my MAC and copied them to a freshly formatted 16 GB class 10 SD card (I used SD card formatter to do this) in the boot directory.
Inserted it in my Raspberry PI 1B and booted.
It started and expanded the directories and started NOOBS, however no OS was listed in Noobs to install.
I redownloaded the file extracted it again and repeated the process three times, but all with the same result.

This is the same procedure I have used on numerous OS  that I installed on my Raspberry Pi and it does work with the standard NOOBS from Raspian.org.

Am I doing something wrong or is this an undocumented feature [Image: wink.png]?
