There used to be GAP events (connect/disconnect). The main purpose for
these events was to allow applications to re-start advertisement when a
connection was lost - on nrf. Unfortunately things work differently on
Linux, which already has this behavior and for which I haven't yet
implemented these events. Therefore I have removed these events and
instead added code to automatically restart advertisement on connection
loss.
Supporting multiple (incoming) connections as a peripheral would be
useful, but is not currently supported.
This changes the previous raw advertisement packets to structured
advertisement configuration. That means you can set the local name not
with a raw byte array but with a normal string.
While this departs a bit from the original low-level interface as is
often used on microcontroller BLE stacks, it is certainly easier to use
and better matches higher level APIs that are commonly provided by
general-purpose operating systems. If there is a need for raw BLE
packets (for baremetal systems only), this can easily be added in the
future.
