RT3S radio not detected in linux

[detournemint]

Says "No Matching Radio Found" Anyway to get it to detect?

This may depend a bit on how you installed qdmr and the distribution.

First, can you check if the radio is detected by the kernel. Call lsusb an look for a VID/PID 0483:df11. It should be named something like STM device in DFU mode. Also, your device should not be in firmware flash mode. Do not press the side buttons while switching it on.

If you installed the Snap package, you need to allow qdmr raw access to USB devices (see https://dm3mat.darc.de/qdmr/install.html) with

snap connect qdmr:raw-usb

to grant the access.

If you installed qdmr by building it from the source code, ensure that the udev rules are installed properly. There should be a file name 99-qdmr.rules in /etc/udev/rules.d/. If it is there try running

sudo udevadm control --reload-rules

to reload these rules (although this should have happened automatically).

If you installed one of the pre-build packages for Ubuntu, Arch, OpenSuSE or Gentoo. It should work out of the box. To investigate it further, install (if not already present) dmrconf the command line version of qdmr. Then run

dmrconf --verbose detect

and dump the output here.

I'm not finding the dmrconf package, i found dmrconfig but it doesn't have that command. I'm running ubuntu and i installed qdmr from the software store

Ok I see two issues here.,

First, when you install qdmr via the software store in Ubuntu, the snap package gets installed by default. This variant should work with the RT3S. However, you need to grant qdmr raw access to the USB devices. This can be done by calling

snap connect qdmr:raw-usb

This should do the trick.

However, even then I see a problem: Your lsusb list you send, did not contain the device. There must be a device listed, that is called "STM device in DFU mode" or something like that. I saw, however, that there was a device called "FT232 Serial (UART) IC". This one and similar chips are used in some cables to connect to HTs. However, not for the Retevis RT3S. There a direct USB connection is used to the MCU within the radio. Are you sure that you are using the correct cable for this device? Does this cable work under windows with the manufacturer CPS?

I was able to get it working using the cable that came with the radio, Thank to you so much
