Hi Iqtidar,
sorry for my late response.
I have already written something related to this topic earlier in this group ... The problems came with the major changes to bluez from version 4.98 to version 5.0. I have ported the bluez-plugin of antidote to the recent version 5 of bluez in order to work with newer version of Manjaro or Debian (but the port makes antidote incompatible with bluez 4.x. But this shouldn't be a problem for the system you are targeting).
Please find attached my port (which is in this case just one changed file). After recompiling antidote, it should work. However, I have only tested my port with Ubuntu 16.04 and Manjaro. I have not tested it yet with Ubuntu 18.04. or newer. Maybe there are new changes to antidote required.
Hope this helps you.
BR Michael
