Connecting to the Boomerang
There are 2 methods to connect to the Boomerang hotspot.
1 - Using the LAN (BMHSPI3 only):
• Type pi-star.local on a web browser in a computer that
is connected to the same LAN
• If the pi-star.local does not work, use the unit’s IP
address instead of pi-star.local
• The IP address can be found through the router or
using an IP address network scanner software.
2 - Using wireless (BMHSPI3 and BMHSPI0):
• Using a laptop or smartphone, look for “Pi-Star” or “Pi-
Star Setup” wireless access point which will be
available after the “Startup” message appears on the
hotspot screen.
• Connect to the Pi-Star WIFI access point. A web
browser should open up automatically open on the pi-
star page. If not, open a web browser to connect to
the default Pi-Star gateway IP address 192.168.50.1

Powering up the unit
1 – Connect the ethernet port to a DHCP
router (BMHSPI3 - LAN)
2 – Connect the power to the USB port
3 – Allow 1 minute for the BMHSPI3 to
boot up and about 2 minutes for the
BMHSPI0. A “startup” message and the
MMDVM logo will appear on the screen
the during this process indicating the pi-
star software is loading. This could take up
to an additional minute to complete
depending on different variables.
Note:
- Wait for the hotspot to bootup before looking
connecting.
- Disconnecting power while booting up or during
operation can cause file corruption.
