Homebrew/MMDVM® connector

You can use this connector to connect to a network which supports the

Homebrew

 or the 

MMDVM®

 protocol, like BrandMeister, TGIF, DMRplus,

Phoenix, DMR-MARC, XLX etc.

The easiest way is to use the 

Quick setup

 to connect to these networks.

This connector supports 2 protocols: 

Homebrew

 and 

MMDVM®

. Use the

Homebrew protocol to connect to BrandMeister network servers, and the
MMDVM® protocol to connect to TGIF, DMRplus, Phoenix, DMR-MARC, XLX etc.
servers.

The default server password for BrandMeister servers is 

passw0rd or password,

but some servers do not use these defaults. In this case take a look at the

BrandMeister wiki

, or ask the server's admin for the password if the openSPOT4

won't connect with the default one.

If you can't connect to a BrandMeister server because the 

authentication has

failed

, then turn off 

Hotspot Security

 on your 

BrandMeister SelfCare

 page, or

use the 

hotspot password

 you've set there as the server password.

If you are using a BrandMeister server in Homebrew protocol mode, you can see
the list of currently linked static, dynamic talkgroups and reflectors on the
openSPOT4's Status page.

Cross mode usage

The Homebrew/MMDVM® connector is a DMR connector, but it supports C4FM
and NXDN® cross modes, and also D-STAR® with the openSPOT4 Pro.
