972274 - B2G Emulator: Suport Bluetooth host HCI pass through

Status: RESOLVED WONTFIX

(Firefox OS Graveyard :: Emulator, enhancement)

Description

[Vicamo Yang [:vicamo][:vyang]]

It would be nice if we can use emulator to connect a physical bluetooth dungle and analyze its packet flow.

To compile emulator with CONFIG_BLUEZ, libbluetooth-dev is required in the host environment.  Besides, due to the same problem we have in bug 897727, Debian libbluetooth-dev and libbluetooth-dev:i386 conflicts with each other, we have to trick Debian a little bit to have "libbluetooth.so" symlinks of both variants.

Working branch: https://github.com/vicamo/b2g_platform_external_qemu/tree/bugzilla/972274/bluetooth-host-hci-pass-through

To have a glance over current status:

1) (Debian Sid) install libbluetooth-dev, libbluetooth3:i386
2) ln -s /usr/lib/i386-linux-gnu/libbluetooth.so.3.13.0 /usr/lib/i386-linux-gnu/libbluetooth.so
3) checkout working HEAD in external/qemu
4) recompile emulator
5) edit ${B2G_ROOT}/run-emulator.sh to include: TAIL_ARGS="-bt hci,host"
6) ./run-emulator.sh
