So I had a look at things. All files refernced are in /opt/dmrlink/ambe_audio So in dmrlink.cfg I have [AMBE_PEER] ENABLED: True RADIO_ID: 312107 IP: 192.168.0.203 PORT: 52345 ALIVE_TIMER: 5 MAX_MISSED: 20 PEER_OPER: True IPSC_MODE: DIGITAL TS1_LINK: True TS2_LINK: True CSBK_CALL: False RCM: True CON_APP: True XNL_CALL: False XNL_MASTER: False DATA_CALL: True VOICE_CALL: True MASTER_PEER: False AUTH_ENABLED: True AUTH_KEY: A1B2C3 MASTER_IP: 192.168.0.203 MASTER_PORT: 50001 I have in ambe_audio.cfg # DEFAULTS - General settings. These values are #inherited in each subsequent section (defined by section value). [DEFAULTS] debug = False # Debug output for each VOICE frame outToFile = False # Write each AMBE frame to a file called ambe.bin outToUDP = True # Send each AMBE frame to the _sock object (turn on/off DMRGateway operation) gateway = 127.0.0.1 # IP address of DMRGateway app toGatewayPort = 31000 # Port DMRGateway is listening on for AMBE frames to decode remoteControlPort = 31002 # Port that ambe_audio is listening on for remote control commands fromGatewayPort = 31003 # Port to listen on for AMBE frames to transmit to all peers gatewayDmrId = 312307 # id to use when transmitting from the gateway tgFilter = 42657 # A list of TG IDs to monitor. All TGs will be passed to DMRGateway txTg = 42657 # TG to use for all frames received from DMRGateway -> IPSC txTs = 2 # Slot to use for frames received from DMRGateway -> IPSC # # The section setting defines the current section to use. By default, the ‘ENABLED’ section in dmrlink.cfg is used. # Any values in the named section override the values from the DEFAULTS section. For example, if the BM section # has a value for gatewayDmrId it would override the value above. Only one section should be set here. Think # of this as an easy way to switch between several different configurations with a single line. # #section = BM # Use BM section values #section = Sandbox # Use SANDBOX section values [AMBE_PEER] gatewayDmrId = 312307 tgFilter = 42657 txTg = 42657 txTs = 2 [ME_SW] # BrandMeister tgFilter = 3123 # A list of TG IDs to monitor. All TGs will be passed to DMRGateway txTg = 3123 # TG to use for all frames received from DMRGateway -> IPSC txTs = 2 # Slot to use for frames received from DMRGateway -> IPSC So AMBE_PEER works fine, I attempted to add ME_SW which only works one way. The way I tested this is by using my dv4mini on 3123 attempting to talk to my repeater. Audio passed from my dv4mini to my repeater, but my repeater (from ASL) will not pass audio to the dv4mini. Also my bridge is setup for 3123 and my local users on the repeater can use 3123 for QSOs. I'm guessing part of my problem is I need to add ME_SW to dmrlink.cfg. Although I'm confused about some of the settings such as using duplicate information, such as ports and IDs. Thanks
