Hi (NB I've resent this as plain text) I've been trying out /tools/3dsp.c on a Raspberry Pi 3. There's some background in this thread that Marcel mentioned http://www.spinics.net/lists/linux-bluetooth/msg62198.html The Raspberry Pi uses the Broadcom bcm43438 chip, which according to the registration documents does support connectionless slave broadcast I don't see any errors, but nothing seems to happen, so have been taking a close look at the code, especially the start_glasses method. In there I see the event masks: https://git.kernel.org/pub/scm/bluetooth/bluez.git/tree/tools/3dsp.c#n316 uint8_t evtmask1[] = { 0x1c, 0xe0, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 }; uint8_t evtmask2[] = { 0x00, 0xc0, 0x74, 0x00, 0x00, 0x00, 0x00, 0x00 }; I thus looked at the spec for set event mask page 2 (section 7.3.69) - but this mask, especially evtmask2, doesn't seem to make sense. Here's the full table (edit resending as plain text): Value Parameter Description 0x0000000000000000 No events specified (default) 0x0000000000000001 Physical Link Complete Event 0x0000000000000002 Channel Selected Event 0x0000000000000004 Disconnection Physical Link Event 0x0000000000000008 Physical Link Loss Early Warning Event 0x0000000000000010 Physical Link Recovery Event 0x0000000000000020 Logical Link Complete Event 0x0000000000000040 Disconnection Logical Link Complete Event 0x0000000000000080 Flow Spec Modify Complete Event 0x0000000000000100 Number of Completed Data Blocks Event 0x0000000000000200 AMP Start Test Event 0x0000000000000400 AMP Test End Event 0x0000000000000800 AMP Receiver Report Event 0x0000000000001000 Short Range Mode Change Complete Event 0x0000000000002000 AMP Status Change Event 0xFFFFFFFFFFFFC0 00 Reserved for future use Only the first two octets (by which I mean the rightmost four digits in the table above, assuming little endianess) are in use. So is it right to say 0xC0 => 8 + 4 + 0 + 0 for the 4th column, which only contains options for 1 (Short range mode) and 2 (AMP Status change) And 0x74 is even more confusing, as there doesn't seem to be any parameters mapped to that. Can anyone help here please?
