Public bug reported:
If a host has 2 adapters, the scanner run for a few second then get an
error msg Could not receive advertising events: Broken pipe, then hci0
turns down when I run hciconfig
hci0: Type: Primary Bus: USB
BD Address: 00:1A:7D:DA:71:13 ACL MTU: 310:10 SCO MTU: 64:8
DOWN
RX bytes:574 acl:0 sco:0 events:30 errors:0
TX bytes:368 acl:0 sco:0 commands:30 errors:0
hci1: Type: Primary Bus: USB
BD Address: 00:1A:7D:DA:71:13 ACL MTU: 310:10 SCO MTU: 64:8
UP RUNNING
RX bytes:221883 acl:0 sco:0 events:8327 errors:0
TX bytes:1027 acl:0 sco:0 commands:67 errors:0
This happend after I updated bluez from 5.62 to 5.63.
If I do scan again, everything works fine with one adapter.
As both adapters use the same mac address, I changed the address of hci0
hci0: Type: Primary Bus: USB
BD Address: 00:01:07:00:47:0E ACL MTU: 310:10 SCO MTU: 64:8
UP RUNNING
RX bytes:1184 acl:0 sco:0 events:66 errors:0
TX bytes:1072 acl:0 sco:0 commands:66 errors:0
hci1: Type: Primary Bus: USB
BD Address: 00:1A:7D:DA:71:13 ACL MTU: 310:10 SCO MTU: 64:8
UP RUNNING
RX bytes:221961 acl:0 sco:0 events:8340 errors:0
TX bytes:3078 acl:0 sco:0 commands:80 errors:0
but the old address keeps reverted back which was not the case in 5.62
I ran scan again while running btmon
