Multicasting Issues in Android Host

Postby Ganesh de » Wed Jun 08, 2011 5:12 am

I am working on USB Connectivity between android 2.1 Host and Windows Mobiles 6.1 device...When I connect the windows mobile device to android host through USB (in RNDIS Mode), It is appearing as 'eth1' interface.

Case 1: I connected my Samsung Galaxy I7500 phone (android phone) to my Host (android) through USB Cable. It was in ECM Mode.It is detecting as 'usb0' device.

Case 2: I connected Windows Mobile to my Host(android) through USB Cable.It was in RNDIS Mode.It is detecting as 'eth1' device.

I connected Samsung phone and tried to send multicasting packets through 'usb0' interface...It is working fine...

Also i connected Windows Mobiles phone and tried to send multicasting packets through 'eth1' interface... But it "Cannot join Multicasting Group"...

Being both USB Devices, Why multicasting is not allowed in virtual ethernet connection(eth1) ?

Please provide me some help...
Thanks in advance

Regards,
Ganesh
