I am trying to publish discover dns-sd services on BNEP network interface. I have a Linux system and one Android phone. I have enabled tethering from my android phone and made the Linux System connect to the BNEP network. After making the set up, I was able to ping between both devices.
My requirement is to publish a service a DNS-SD service from the Linux System and discover that from the Android device. I am using Avahi for publishing the service from the Linux System and using an App from Android app to browse the services.
The issue I am facing is, the service is published locally in the Linux system but not on the BNEP network(because when I started a browse from Linux for the service published in Linux, the discovery is successful)

I have captured the tcpdump when I started the discovery from the android phone to check if the response is coming to the phone. And I found that the message is coming properly.
Android Phone IP : 192.168.44.1
Linux Device: mx6q.local

Avahi Config file

I think some configuration is missing from the Linux system which I am not able to identify, Please help me.
N.B: 1. When I publish a DNS-SD service from the Android Device, I can discover the same on the Linux system but the reverse is the problem. 2. Same set is working with Wifi, Ethernet and USB (rndis) network interface
