由于时间关系，本博在整理文章时，均为蜻蜓点水，不做深入教程，原因是懂的自懂，不懂的知道太多也没什么意思。

其实AllStar就是我另一篇博文提到的DVSwitch (Server)， USRP是一种网络电话协议，可以用专用的电话，IP电话拨号接入，实现模拟转数字。DVSwitch 安卓客户端就是一个基于USRP协议的客户端，可以间接接入DMR服务器。

If I understand correctly, you are trying to use MMDVM hardware for AllStar, it is possible if you are trying to use an actual MMDVM modem, NOT a hotspot board. There is a branch of MMDVMHost that can talk to AllStar via USRP. You would have MMDVMHost and AllStar installed. This could be on the same host or different hosts on the same LAN.

If you are trying to use analog hardware to operate AllStar, DMR, D-Star, NXDN, P25, then you can add DVSwitch Server to your AllStar node and access all modes from an analog radio (and Android, HTML)

Hope this helps,

MMDVM_Bridge and Analog_Bridge.

A dummy node, 1999, was added to rpt.conf to facilitate the bridge:

[1999]
; CHANNEL DRIVER SETTINGS
rxchannel = USRP/127.0.0.1:34001:32001
duplex=0
hangtime=0
althangtime=0
tx_timeout=180000
idtime=600000
rx_timeout=180000
nounkeyct=1
holdofftelem=1
telemdefault=0
linktolink = no
idrecording = |ie
idtalkover = |ie

Analog_Bridge is listening on port 34001 so that’s how it’s talking with Asterisk.
