I am trying to do some troubleshooting of BlueTooth connectivity and
wouild like to see the packets, or maybe make a simple slave (like GPS
slave).
I have this BlueTooth USB dongle:
ubt0: <vendor 0x0a12 product 0x0001, class 224/1, rev 2.00/19.15, addr
3> on usbus1
Then I stop bluetooth (master) stack, so that ubt0 has no hooks.
Then I direct all packets to ng_hole node:
ngctl mkpeer ubt0: hole hook hhook
Then I run DTrace script showing when some msg or data comes:
#!/usr/sbin/dtrace -s
fbt::ngh_rcvmsg:entry
{
printf("ngh_rcvmsg * ");
}
fbt::ngh_rcvdata:entry
{
printf("ngh_rcvdata * ");
}
Attaching the hook to ubtN causes it to start bulk and interrupt
transfers (according to the code).
Then I turn the cellphone (master) into discovery mode. But nothing
comes to the ng_hole at all. Supposedly, master in discovery mode should
announce itself to slaves.
Why no messages arrive to the hole? Where is the problem?
