  The IPv6 over Bluetooth Low Energy (BLE) standard defines the transfer of IP
data via BLE connections. This connection-oriented approach provides high
reliability but increases packet delays and requires substantial overhead to
manage BLE connections. To overcome these drawbacks we present the design and
implementation of IPv6 over BLE advertisements, a standard-compliant
connection-less approach. We deploy our proposal on low-power IoT hardware and
comparatively measure key network performance metrics in a public testbed. Our
results show that IP over BLE advertisements offers network performance
characteristics complementary to IP over connection-based BLE, trading lower
reliability for shorter~latency.
