Hi
I am testing samples/bluetooth/beacon with QEMU.
The version of zephyr is recent master branch.
1)
The beacon sample test with local Bluetooth adapter on Linux PC, gives the
init failed error
[QEMU] CPU: qemu32
qemu-system-i386: warning: Unknown firmware file in legacy mode:
genroms/multiboot.bin
Starting Beacon Demo
Bluetooth init failed (err -35)
2)
So, I test the sample "beacon" with emulation support with BlueZ.
Attached wireshark capture.
Could someone verify if my setup (tools and commands) is correct or I am
missing something here?
For further bluetooth tests, has anyone tried the tools "l2ping" and
"l2test" ?
When I do "make qemu" : Bluetooth is initialized and Beacon started. BD
address is 00:aa:01:00:00:23 (public).
However, "hciconfig -a" gives
[bt] [ERR] read_payload: Not enough space in buffer
[bt] [WRN] hci_cmd_done: pool id 1 pool 0x00405098 != &hci_cmd_pool
0x00405078
I have following running in different terminals.
$ sudo ./btvirt -l2

$ sudo tools/btproxy -i 0 -u

I don't get this error when using a real controller:

Perhaps this has something to do with the emulator as it is now
emulating 5.0 features there maybe something not working quite right.
