Supported Radios

Handi-Talky Commander works with Benshi-protocol radios connected over Classic Bluetooth (RFCOMM / SPP) — the same radios supported by upstream HTCommander.

Supported models

• BTech UV-Pro, UV-50Pro
• Radioddity GA-5WB, DB50-B Mini
• Vero VR-N75 / VR-N76 / VR-N7500 / VR-N7600

Most testing to date is on the BTech UV-PRO. Other Benshi-protocol radios use the same command set and should work, but may be less exercised.

How it connects

These radios use Classic Bluetooth RFCOMM / SPP (a serial-port profile), not BLE GATT. That has a few practical consequences:

• You pair in your OS Bluetooth settings first (see Getting Started).
• On Linux, the app uses BlueZ (raw RFCOMM/SDP).
• On macOS, it uses an IOBluetooth bridge, because Apple's public CoreBluetooth API has no classic-RFCOMM support. (This is why the macOS port needed dedicated Bluetooth work — see Architecture.)

"Digital mode" caveat (Benshi UV-PRO)

The radio's TNC (KISS path) — used by Winlink, BBS, and the App-TNC APRS beacon — requires the radio's "Digital mode" to be OFF. Digital mode is only for the radio's built-in beacon and disables the TNC. The two are mutually exclusive.

Not sure if yours works?

If you have a Benshi-protocol radio not in the list above, try it and open an issue with the model and what you observe — including a Bluetooth debug log (see Troubleshooting).
