Hi, my name is Julian I am from Colombia, I am a newbie and this is my first post.
I want to capturate Azimuth and Elevation in realtime using Matlab and serial Communication
I had installed Gpredict 2.3.37 on Windows 10
Also Hamlib w32 3.3
And also uploaded “satnogs-rotator-firmware-master” to an arduino UNO from
I created a Module in gpredict with my location and a generic antenna to communicate with hamlib on localhost and all default options
Then, with the Arduino UNO plugged in, I started hamlib with the following line on CMD:
“C:\Program Files (x86)\hamlib-w32-3.3\bin\rotctld” rotctld -m 204 -r COM10 -s 9600 -T 127.0.0.1 -t 4533 -C timeout=500 -C retry=0 -vvvvvvvv > pause
Everything looks fine untill now but then when I hit “Engage” on gpredict the CMD console shows this ERROR:
read_string(): Timed out 1.49158 seconds after 0 chars
easycomm_transaction read_string failed with status -5
easycomm_rot_get_position got error: -5
No, don’t have any electronics mounted besides the Arduino UNO with no Shield nor any PCB, just a Serial to USB converter used for MATLAB communication
The other day I did the same and it worked, here is a video:
Any ideas on why is it not working now?
I also created a Station on SatNOGS network and used “image_2020-03-04-Raspbian-SatNOGS-lite” or “artifacts.zip” on a Raspberry Pi 4 and configured the basic setup, the /dev/ttyACM0, and connected the arduino but I didn’t get any data on the serial port apart from “ID;” or “FA;”
I feel this is a configuration related problem but I’m no expert, I hope you can help me
Thank you for the long reading and any help will be very much appreciated.
