This patch addresses an issue where the some RTK BLE dongles fail to perform
an HCI reset after the transport is torn down and re-instantiated. To address
that, we prevent crashing the background threads when invalid data comes in,
and time out if no response is received within a fixed amount of time. When
the timeout occurs, we retry the reset, and ultimately skip over reading the
local version information if that fails.
* Add BaseBumbleException as a "real" root error
* Add several core error classes and properly replace builtin errors
with them
* Add several error classes for specific modules (transport, device)
Further adventures in porting tools to Rust to flesh out the supported
API.
These tools didn't feel like `example`s, so I made a top level `bumble`
CLI tool that hosts them all as subcommands. I also moved the usb probe
not-really-an-`example` into it as well. I'm open to suggestions on how
best to organize the subcommands to make them intuitive to explore with
`--help`, and how to leave room for other future tools.
I also adopted the per-OS project data dir for a default firmware
location so that users can download once and then use those .bin files
from anywhere without having to sprinkle .bin files in project
directories or reaching inside the python package dir hierarchy.
