Minimum Debian/Ubuntu support

[fromage9747]

I came across your library and have successfully run it in Debian 12. I have a device that I can't upgrade and is on Debian 7 but as this uses the low level HCI commands, I thought that I could get it to run there.

I managed to compile it and start it, but it crashes my bluetooth and displays the message:

Initialising...
No root permission or Bluetooth (hci0) is off or crashed
Must run with root permission via sudo as follows:
  sudo ./btferret (for C) or  sudo python3 btferret.py

What would be the minimum version/OS that this can run on? Or maybe I need to update something?

Any help would be greatly appreciated.

Looks like this is the problem, Unable to load keys to adapter_ops: Function not implemented (38)

I do not have Debian 7, so I can't check it myself. From the syslog it looks like hci0 is OK. Check by running:

hciconfig

See if you get a listing for hci0.
Try enabling or disabling hci0 first:

sudo hciconfig hci0 down
OR
sudo hciconfig hci0 up

Or try shutting down bluetooth before running btferret:

sudo service bluetooth stop

Or - this is a bit more complicated because the library must be edited. Get more information about the failure by enabling verbose mode and save the results to a text file as follows. I'm not sure if you're running C or Python. If Python - run btfpy.py build again.

In btlib.c file Line 1342

  set_print_flag(PRINT_NORMAL);  
  // set_print_flag(PRINT_VERBOSE);

CHANGE TO

  // set_print_flag(PRINT_NORMAL);  
   set_print_flag(PRINT_VERBOSE);

Then run this code.

C

int main()
  {
  init_blue("devices.txt");
  output_file("bug.txt");
  return(0);
  }


PYTHON

btfpy.Init_blue("devices.txt")
btfpy.Output_file("bug.txt")
