Re: Thumb DV Baud rate change #ambe #ambeserver #thumbdv

 

Gary,
Yes, I would as the task to change the band rate is quite intensive.
They are identical except for the band rate.
I will await your research.
Please let me know.
Thanks

Hi Don. I recall reading a how-to from John Hays of NW Digital Radio, where he explains how to do "surgery" to an Original ThumbDV to change the baud rate from 230,400 to 460,800, I believe that it involved in cutting a couple of traces on the PCB and re-jumpering.
I'll see if I can locate the document.

ThumbDV ambeserver intermittent transmission #ambeserver #thumbdv

roylosbanes@...
 

Hello everyone, I recently setup ambeserver linke to peanut and to our YSF Reflector which is alos link to our club's repeater (Yaesu DR1X). We recently encountered intermittent transmissions when TX from Peanut App to C4FM. All other modes don't have any issues. So from Peanut to any other modes, TX is ok, RX to peanut from other modes also have no issues. So the main issue is why are we having intermittent transmissions from Peanut going to YSFReflector? Anyone here encountered the same issue?
-Setup:
ThumbDV connected to RPI3B+ with 30mbps internet connection
MMDVM Repeater setup for YSF connected to Motorola GM300>Linked to Yeasu DR1x

Thanks,

Thanks John,
That does work. I've tested and it does start automatically on reboot. I'm not really sure of the security ramifications of running this way especially since pi this will be port forwarded through to the internet so I can use it remotely.
I wonder if there is anything I could add to the systemctl cmd (-user or something) when starting Ambeserver rather than changing the user to root.
Again thanks for all your help in getting this going. I learned a few things LOL.

Re: PiDV, AMBEserver and Buster

John,
Thanks for the help. 
I'm definitely a noob when it comes to a lot of Linux  commands and I appreciate you sending me the references. I will study the documentation to get more familiar with the system administration commands. I had tried a few things on my own researching the problem and decided to start fresh last night and here is where it stands.

Re-installed the OS and configured the pi using latest version from raspberry pi web site
Using sudo-raspi config, I set up the serial port turning off the boot console and enabling the com port
Ran the AMBEserver3.py test to verify the PiDV serial communications. (FYI, I had to modify the AMBEserver3.py file to delete the tm symbol after ThumbDV on line 22 as my python program couldn't understand the symbol)
Test runs fine so I proceed with the ambesocktesy.py running AMBEserver -i /dev/ttyS0 and that runs fine too.
 In fact I operated BlueDV on my PC as additional verification of the AMBEserver.

The wheels come off when I try to run the server as a service using sudo systemctl enable ambeserver@ttyS0 and  sudo systemctl start ambeserver@ttyS0 and  sudo systemctl status ambeserver@ttyS0
 I get the ever troubling error " AMBEserver: Unable to open GPIO export interface: Permission denied"

I then change the ownership of /dev/ttyS0 with:
sudo chown root:dialout /dev/ttyS0
sudo chmod 660 /dev/ttyS0
after testing I get 
ls -l /dev/tty[AS]*
crw-rw---- 1 root dialout 204, 64 Oct  1 17:48 /dev/ttyAMA0
crw-rw---- 1 root dialout   4, 64 Oct  2 09:14 /dev/ttyS0

but when I start the server again the same problems. Server fails with the GPIO permission failure and
the ownership of ttyS0 reverts back to this state.
ls -l /dev/tty[AS]*
crw-rw---- 1 root dialout 204, 64 Oct  1 17:48 /dev/ttyAMA0
crw--w---- 1 root tty       4, 64 Oct  2 09:21 /dev/ttyS0

somehow the  sudo systemctl start ambeserver@ttyS0 resets the ownership of of ttyS0

Again being a noob, I'm not sure where to go from here. I'm hoping this info will give you some insight as to how I can proceed from here.

Thanks again for your help.
