As discussed offline:

• Offloaded ScanFilters may or may not work depending on the OS/vendor peculiarities. You could try using emulated scan filters.
• Offloaded ScanFilters usually check only the primary Advertisement packet. If a name (or any other scan property) is transmitted in the Extended Advertisement Packet will most likely not work because the Android does not send Extended Advertisement Inquiry when doing scans with ScanFilters. If you control the peripheral you should be able to transmit the filter elements in the primary Advertisement Packet
