skygate's Introduction

skygate - Modular Python/GTK HAB Receiver and Uploader

HAB receiver software for tracking LoRa and RTTY payloads, and uploading telemetry and image data to Habitat along with the receiver's GPS position. Uses external software (dl-fldigi) to decode RTTY, using audio from a real radio or from an RTL-SDR using rtl_fm program.

Receiver

This software is written for Python 3.

It needs these items to be installed:

sudo apt-get install wmctrl rtl-sdr dl-fldigi ssdv

Raspbian Configuration

Enable the following with raspi-config:

Interfacing Options --> SPI --> Yes

If you are using a GPS HAT, then you also need to set the serial port:

Interfacing Options --> Serial --> No (login) --> Yes (hardware)

Loopback Sound Device

Create a new ~/.asoundrc file using the supplied file, with

cp ~/skygate/.asoundrc ~

Usage (Autostart)

Edit the following text file:

~/.config/lxsession/LXDE-pi/autostart

and append these 2 lines:

@/home/pi/skygate/skygate/start_gateway.sh  
@/home/pi/skygate/skygate/start_rtty.sh

Usage (Manual)

Set up the loopback audio device, with

modprobe snd-aloop pcm_substreams=1

Start the RTL SDR software with

rtl_fm -M usb -f 434.100M -s 192000 -r 8000 - | aplay -f S16_LE -t raw -c 1

Start dl-fldigi with

./src/dl-fldigi --wfall-only

At startup, enter your receiver callsign. Then, on the audio config page, select Port Audio and the first device.

Then configure dl-fldigi through its menus (these settings suit pytrack and Pi In The Sky default settings):

Op Mode --> RTTY Custom --> Set 300 baud, 8 data bits, 2 stop bits, 830Hz shift

(or, if not using SSDV) 50 baud, 7 data bits, 2 stop bits, 830Hz shift

dl-fldigi includes an fldigi bug that causes it to sometimes fail on startup with an error code of 11. Try again if this happens.

The receiver program can be started manually from a terminal window in an X session with:

cd
cd skygate/gateway
python3 skygate.py

skygate's Issues

LoRa: RSSI Display

Hello,

To decide if a signal is good or if the reception strength has changed, it would be good to display the RSSI level on the main screen or lora screen.

Would that be possible?

No GTK enabled python3

Hello install normal via apt on stretch:

whats wrong?

How can i call the test files

Hello,

i'll test the lora connection between this boards:

Tracker: dragino Lora/GPS Hat (http://wiki.dragino.com/index.php?title=Lora/GPS_HAT)
Skygate: pi-gate (https://github.com/pi-gate/driver)

Problem i can't start the test_lora.py, maybe i'm wrong:

i@XSkyGateway:/usr/lib/python3/dist-packages/skygate $ python3 ./test_lora.py
Traceback (most recent call last):
  File "./test_lora.py", line 1, in <module>
    from skygate.lora import *
  File "/usr/lib/python3/dist-packages/skygate/skygate.py", line 7, in <module>
    import skygate.misc
ImportError: No module named 'skygate.misc'; 'skygate' is not a package

How can i call this files on my raspbian with installed skygate or from sources.

HAB Ballon is tracking?

Hmm, i don't found a balloon tracking on habhub tracker.habhub.org ... just the gps position of chaising car, but where is my balloon data on this tracker?

sed error on install

The final part of the install, the autostart script throws a sed error:

sed: -e expression #1, char 1: unknown command: `@'
sed: -e expression #1, char 1: unknown command: `@'

Open repo to public

@ghollingworth We've soft launched this project and have pages pointing to it, can the repo be made public please?

Problems with skygate and asoundrc

Hello.

At first I have to admit that I‘m pretty new to all things Pi and Linux.

I followed the description step by step, I think. Installed ssdv dm-fldigi rtl-sdr etc.

I tried to create the file under home/Pi/skygate, but it told me there is no such directory.

Python3-Skygate is installed.

Would be huge if one could help a beginner. #

loraChannel default=1

Please let the user decide which module he want to use:
https://github.com/raspberrypi/skygate/blob/master/skygate/skygate.py#L106

IMHO, a good candidate for setup screen. (Channel 0 or 1)

I test and try to find the bug for houres, better to display the connect data @ console to find the problem:
@XSkyGateway:~/skygate/skygate $ python3 ./skygate.py
Cannot get client list properties.
(_NET_CLIENT_LIST or _WIN_CLIENT_LIST)
Cannot get client list properties.
(_NET_CLIENT_LIST or _WIN_CLIENT_LIST)
LORA: Ch: 0 Freq: 434.434 Mode: 1

apt install doesnt work

Hmm, whats wrong here?
