Android Peers Don't See Each Other

Recommended Posts



I am using the current v2.1.1 on the Windows machine and also the current 2.0.107 on HTC One M8 and a Nexus 9. These devices are using the same LAN. Windows client has LAN broadcast enabled.



     The two android devices are not seeing each other. They see only the Windows machine.



  • How can they be made to see each other so they can REALLY use the mesh topology that Sync promises to be using?
  • Is this something only the PRO version has? (using free now)


Thanks for any help!

All Sync instances (regardless of pro/free license) use UDP multicast to port 3838 for local peer discovery as well as tracker server. I suggest to verify:


1) if your router is multicast aware and in general routes multicast traffic

2) if your network has range of local IPs according to RFC1918 (192.168.x.x, 172.16.x.x - 172.31.x.x, 10.x.x.x)

3) if your router / firewall allows connection to internet over port 3000 (that for the tracker server in case something is wrong with multicast).
