@N8PC The executable is actually located at /usr/sbin/simpleusb-tune-menu
@Smalltalk Yes, you can, but it’s a bit more difficult because you need to know what the “menu codes” are by looking them up in the source code for simpleusb-tune-menu.
The error you are seeing means that there may have been a problem connecting to the local asterisk to run the command. Restarting would probably fix this. But you can also test the following command and report back what happens:
sudo asterisk -rx "susb tune menu-support 0"
Make sure you use the double quotes. If this reports back a string of numbers and commas like
500,500,0,1,1,0,1,0,2,2,0,0
then that means it should be working and you can try sudo simpleusb-tune-menu again.
If instead you receive some sort of error message, then you can post that for more help.
This suggests a configuration issue either with “rpt.conf” (the “rxchannel = SimpleUSB/node#” variable/value for the node) or “simpleusb.conf” file (a missing/mismatched “[node#]” stanza) … and remember to restart asterisk after making changes to the .conf files.
The asl-menu “Interface Tune CLI” option executes the simpleusb-tune-menu command. That code, in turn, ends up using the “susb tune …” commands to interact with the SimpleUSB channel driver.
