Brew Interconnect

Brew Interconnect

Brew is the protocol FlowStation uses to connect your local cell to a wider TETRA network — TetraPack or BrandMeister. Once connected, group calls and SDS messages flow between your cell and the network core.

Configuration

[brew]
host = "core.tetraflow.ro"
port = 9000
tls = true
username = 123456700
password = "your_password"

Field	Description
host	Brew core hostname
port	Brew core port
tls	Use TLS for the connection
username	Your hotspot / node number
password	Hotspot password

What flows over Brew

• Group calls — calls on networked talkgroups are bridged in both directions
• Individual (P2P) calls — full-duplex P2P works across Brew
• SDS messages — text forwarded to/from the network

Connection status

The dashboard System tab shows live Brew connection status. If it shows disconnected:

1. Check host/port reachability from the Pi
2. Verify username/password
3. Confirm tls matches what the core expects
4. Check the Log tab for Brew handshake errors
