Helge replied to the topic 'Astroberry Server - HAT' in the forum. 15 hours 14 minutes ago

Dear Radek,

Wanted to share some pictures showing the „Astroberry-HAT“, which hosts the stepper driver (A4988) for the astroberry-focuser and the connection to the gps breakout board, as well as the circuit for the reset / shutdown button / led. The HAT receives the 5v input for the stepper and the Raspberry from a 12v to 5v converter. From the HAT 3,3v go to the gps board. Also the HAT connects the RX/TX pins.

The mount is connected via Bluetooth. Only for the ASI cams I need the RPi USB plug. The focuser / stepper is connected via a 5pol MIDI cable.

If of interest to anyone, I can provide more detail description.

Thank you once again for the astroberry server + drivers!

Helge

Hi Rob,

Many thanks for your reply. Actually, I am using the astroberry server, headless. I guess it may not have the dummy driver installed. I have seen your instructions. The HDMI settings were already configured as suggested. I will then give your dummy driver a try and revert.

Best, Helge

Great, now it is working. Not sure what made the difference, I tried again back home, updated /etc/default/gpsd by adding „-b“. I did not touch the ntp.conf file.

Either it is the different position, the „-b“ or just luck. Anyway appreciate the support received!

Hi Rob,

I have read about the issue with a blank screen you observed for the Rock64. I wonder if it is the identical issue I occasionally observed with the Raspberry (which I recently thought I might have resolved, see my post in the astroberry thread, - but then it was not)..

If this fix can help also for my Raspberry (astroberry server), then I just need to download your script „installdummyvideodriver“ and execute, correct?

Many thanks! Helge

P.S. I have put aside the Rock for some time, since I cannot run the astroberry-diy drivers, due to the different chip behind the GPIOs. Have you by chance identified a robust library to address the GPIOs?

This is the lib I found some time ago: github.com/swkim01/RPi.GPIO-PineA64

Though as it looks to me, it cannot directly replace the BCM2835-based commands, I found in Radek‘s script, see for instance:

github.com/rkaczorek/astroberry-diy/blob/master/rpi_focus.cpp

Unfortunately, my programming skills are close to zero, otherwise I would feel tempted to convert for the Rock64! :unsure:

Thanks a lot! With the minicom command, I am receiving a NMEA datastrea („raw“).

„id gpsd“ gives: uid=123(gpsd) gid =20 (dialout) groups = 20 (dialout), 5(tty)

Not sure if this is expected?

I also entered the following command, but probably it did not make a lot of sense and the result was confusing me:

gpsd -N -D3 /var/run/gpsd.sock following which I received error messages that can‘t bind to IPv4 and 6, suggesting that „maybe gpsd is already running“

Can I discard this kind of result?

If - as you say - the serial device is working, maybe I need to connect to an external antenna - I was relying on the antenna that is placed on the board.

First I run sudo killall gpsd.

I checked the connection with sudo cat /dev/ttyS0 and received a datastream in NMEA format, but mostly zero values, please see also previously attached screenshot (see bottom row of top left window). Does it mean that the serial connection works?

When starting up minicom, I am not getting a lot of information, except it says port/dev/tty8 - not sure why tty8. But no datastream or anything else.

Which command is needed to check baud rate? The wiring is fine, checked again.

I have been trying to get above gps board up and running, following these instructions:

learn.adafruit.com/adafruit-ultimate-gps...aspberry-pi?view=all

Looks I am not receiving any meaningful data, the NMEA sentences coming in on gpsmon contain zero’s but no positional data, but time only. Needless to say, „no fix“.

I wonder whether someone more experienced could tell from the screenshot whether this has to do with poor configuration or just signals being too weak?

N.B. I also applied recommendations from Radek in another thread on gps.

Thanks inadvance! Helge

Helge replied to the topic 'Astroberry Server - wlanconfig' in the forum. 6 days ago

Resolved. I have put a # in front of auto wlan0 in the /etc/network/interfaces file. Now the hotspot is coming up, as it used to.

I guess going forward I will rather use the ethernet.

Helge replied to the topic 'Astroberry Server - wlanconfig' in the forum. 7 days ago

For some strange reason I can no longer access the RPi via browser, vnc or ssh. I am actually away from home, i.e. from my WLAN, maybe this is the reason. After powering up the RPi, it takes 5-10 minutes until I can see the astroberry as available network, but connection fails. Only a one or two times, I could see the astroberry desktop, then disappearing.

Help would be greatly appreciated.

Hi Radek,

Wanted to share this one: for some time I had - from time to time - issues with a „black“ screen when establishing remote connection between laptop and the RPi (astroberry server). Usually fine after reset. Since I have been editing the config file setting for hdmi_ignore_edid, it did not happen again. See also this link:

support.realvnc.com/knowledgebase/articl...-on-the-raspberry-pi

I am not sure if that makes sense, but seems to help.

Best, Helge

Hm...not sure if I can be of any help. To be honest, I am myself still fairly new to all this. Just in case this is useful, I copied below the content of what is written in the wpa_supplicant file, which you can access with the following command: sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

Maybe this is also useful (but I am sure you already found this or similar pages): www.raspberrypi.org/documentation/config...less/wireless-cli.md

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={

Hi James,

I assume you were using the wlanconf command (see section how to configure, attached link), correct?

github.com/rkaczorek/astroberry-server

I remember that I once also had the problem with networks not being accessible or network adapter. Did you try “ipconfig” to check network status? There are many hints to restart wlan0 on the internet (but better not to change any of the scripts - not needed!).

Good luck!

Helge created a new topic ' Startup Script to bind Bluetooth' in the forum. 2 weeks ago

Hi.
I have created a desktop launcher to a) bind to the bluetooth adapter and b) to start Kstars in one go. When initiating the script manually in the terminal (just enterting the name), I can verify that binding took place (running ls -al /dev/rfcomm0). When initiating the script via clicking on desktop icon, this is not working. I think it must have to do with "sudo", so I added a line using "visudo", but that did not help, i.e.

"astroberry ALL= NOPASSWD: /usr/local/sbin/startup"

This my script (path /usr/local/sbin/startup), for which I run "sudo chmod +x startup":

#!/bin/bash

sudo rfcomm bind hci0 20:17:09:18:52:58 1
sleep 10
sudo chown astroberry /dev/rfcomm0
kstars

Under path astroberry/Desktop/Startup, I have placed a file as follows:

[Desktop Entry]
version=0.1
Name=Startup
Comment=Bluetooth
Exec=/usr/local/sbin/startup
Icon=/home/astroberry/Pictures/Gold_Telescope.png
Terminal=false
Type=Application
Categories=Utility; Application;

Any ideas really appreciated!

Best, Helge

Update: tried separate power supply for the 3.3V input to the module, situation unchanged.

Would be great if someone had an idea why gps is not connecting - strange, since it did before!
