ln -s libgpiod.so.ANY libgpiod.so

This is a workaround to make it work: I had to go to a Raspberry Pi running Debian 12, which has the correct library version for alterfrn to function.

On the Debian 12 Raspberry Pi:

root@pibao2:/usr/lib/aarch64-linux-gnu# lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 12 (bookworm)
Release: 12
Codename: bookworm

root@pibao2:/usr/lib/aarch64-linux-gnu# uname -m
aarch64

root@pibao2:/usr/lib/aarch64-linux-gnu# ls -lrat | grep -i libgpiod.so
-rw-r--r-- 1 root root 67512 Jan 5 2023 libgpiod.so.2.2.2
lrwxrwxrwx 1 root root 17 Jan 5 2023 libgpiod.so.2 -> libgpiod.so.2.2.2

I copied this library to the Raspberry Pi running Debian 13 and placed it in:

root@pibao:/usr/lib/aarch64-linux-gnu# pwd
/usr/lib/aarch64-linux-gnu

root@pibao:/usr/lib/aarch64-linux-gnu# ls -lrat | grep "libgpiod.so.2"
-rw-r--r-- 1 root root 67512 Oct 3 16:22 libgpiod.so.2.2.2
lrwxrwxrwx 1 root root 17 Oct 3 16:23 libgpiod.so.2 -> libgpiod.so.2.2.2

With this, I was able to start the alterfrn client:

FRNClientConsole.Linux-aarch64.r7312

To make GPIODEV PTT work, the configuration used is:

##### GPIO-DEV for Linux
PTT=GPIODEV:/dev/gpiochip0:6:I

This corresponds to the GPIO configured by Debian 13 for Raspberry Pi OS:

root@pibao:/usr/lib/aarch64-linux-gnu# ls -lrat /dev/gpiochip0
crw-rw---- 1 root gpio 254, 0 Oct 2 20:15 /dev/gpiochip0

Which is the same as on Debian 12:

root@pibao2:/usr/lib/aarch64-linux-gnu# ls -lrat /dev/gpiochip0
crw-rw---- 1 root gpio 254, 0 Oct 2 23:17 /dev/gpiochip0

Summary

Either alterfrn needs to be updated to use libgpiod.so.3 for future Debian versions,

Or you have to use this workaround with libgpiod.so.2 to make GPIODEV PTT work on Debian 13.

Regards.

In the newer Debian versions used on Raspberry Pi 3, 4, and 5—specifically Debian 13—alterfrn cannot run with the RADIO/PTT option set to GPIODEV.

The reason is that Debian 13 uses libgpiod3, whereas alterfrn requires libgpiod2. When you try to start alterfrn with GPIODEV, it fails and displays the following error:

ERROR: PTT: Radio interface type "GPIODEV" is not supported on the system. Install gpiod library

Even if you have gpiod and libgpiod3 installed, alterfrn cannot use GPIODEV because it specifically looks for libgpiod.so.2, which is provided by libgpiod2. Since Debian 13 only includes libgpiod3 by default, the interface is unsupported

You need to run AlterFRN client with debug parameter like:

FRNClientConsole.Win32.r7312.exe debug

save and run it!

Unfortunately, I was unable to run VOX as a radiogateway on any version of alterfrn windows

plz

Good day, there is a video of how this client works in windows, mainly the area of ​​adding Users, 73s from Panama

Buen día, hay un video de como funciona este cliente en windows, principalmente el área de agregar Usuarios, 73s de Panamá
Thanks

Hey..

Work good..
