The central.c application is working fine on my machine. So can you provide more information about when this error occurs? Did you change any code? Which adapter method is giving you the error?

You can also try to see if everything works when using the 'bluetoothctl' command.

i made a couple changes, otherwise the code would not compile: (agent.c and application.c) to include errno.h otherwise, no change

i am running ubuntu 18, bluetooth 5.53

Right. Bluez 5.53 is super old and definitely not supported. The current version is 5.70. Try upgrading...

Not sure if it will work on Ubuntu 18 either. I am 22.04....but I'd first try to see if upgrading Bluez to a newer version solves your problem.

The examples compile file on my machine and no changes should be necessary
