Add setting and install logic for usb bluetooth module

[Marvo2011]

Some users have trouble with the integrated bluetooth in Raspberry Pi's, here I add a setting and install logic for an usb bluetooth module.

Usage:

• buy a usb bluetooth module with BLE support (bluetooth version > 4.0)
• add BLUETOOTH_USE_USB = True to config.ini
• run /data/etc/dbus-serialbattery/reinstall-local.sh
• do a reboot!

Should fix: #777
Should supersede: #830

Did you test this also with Ruuvii Bluetooth sensors?

[Marvo2011]

@mr-manuel oh no, I have no ruuvii sensor. Do you have an other idea to test this ?

[mr-manuel]

Unfortunately not. I think on the Discord server there are some users with Ruuvii sensors, but probably without Bluetooth USB adapter.

[Marvo2011]

@mr-manuel the ruuvii sensors are not really cheap, I have no usage for it. I think we must wait for some one that can test it.

Sorry for sounding stupid I have had nothing but disconnects with my pi’s and jbs’ After adding the usb can you confirm the version to install please /nightly dev?

[Marvo2011]

Nightly dev but with my edits from the PR, there is still open. That means not included to any branch. But you can edit /u-boot/config.txt manually. Replace all "miniuart-bt" with "disable-bt" and reboot the pi.

Thank you will try when back

[mr-manuel]

Please add a note to the config.default.ini, that this was not yet tested with Ruuvi tags or other Bluetooth devices. After I will merge this.

@mr-manuel Thanks, note is added.
