I have been working with the Bluetooth on the Dragonboard and all is running great with it.
I am now looking how to improving the testing of what I have done. This is when I found that BlueZ has an emulator as part of the tools (if you build it from source) that allows you to create virtual adapters on your machine which would be very helpful. However this does not seem to be working on the Dragonboard:
linaro@linaro-alip:~/bluez/bluez-5.43$ sudo ./emulator/btvirt -l2
Bluetooth emulator ver 5.43
Failed to open Virtual HCI device
I posted a question in the BlueZ mailing list but did not get any response.
The emulator seems to run OK on an x86 box that I tried it on. However it does not seem to want to run on a Dragonboard. Nothing seems to be logged to btmon or syslog so I do not know how to go about debugging this.
Has anyone got any suggestions about how to debug this?
Thanks in advance,
