DMR: start a call to the IP address query ID (by default it's 9997). In
DMR mode, voice announcements are sent to TG9, so to hear them,
make sure you have TG9 in your radio's RX group list.
D-STAR®: start a call to the repeater info callsign .......A (7 spaces
and an A, replace dots with spaces), or enter DTMF code B.
C4FM/Fusion®: enter the Special command/cross mode private call
DTMF code (by default it's *) followed by DTMF code B.
NXDN®: start a call to the IP address query ID (by default it's 9997).
P25: start a call to the IP address query ID (by default it's 9997).
On Android and iOS phones, you can use MDNS/Bonjour and network
discovery applications. A recommended app for Android is Fing Network
Tools.
Notes: Android phones do not support LLMNR or MDNS name resolving so
http://openspot4/ and http://openspot4.local/ won't work. Use SharkRF Link or
enter the IP address of the openSPOT4 into the browser to open the web
interface.
If http://openspot4/ and http://openspot4.local/ do not work on your non-
Android device then make sure multicast data is not disabled on your Wi-Fi
network. Some Wi-Fi access points and routers have multicast data disabled by
default. This is required for LLMNR and MDNS name resolving.
