 - **BLE connectivity**, scan for devices, select default device, connect to default device on startup, must be explicitly enabled from settings, requires location permission for scan, modem must conform to [BLE KISS API](https://github.com/hessu/aprs-specs/blob/master/BLE-KISS-API.md) (BLE service, RX/TX characteristics UUID), no authentication
 - **TCP/IP connectivity** on startup, application can connect to TCP/IP based modem and operate through the network, for example, with [Direwolf](https://github.com/wb2osz/direwolf) application and your existing analog transceiver
 - **Voice Codec2 mode selection**, which allows you to select various Codec2 modes from 450 up to 3200 bps on the fly, sender and receiver should agree on the codec mode and use the same codec mode on both ends as Codec2 mode negotiation between clients is not implemented at the moment
-- **Sound modem**, use phone microphone/speaker to send and receive data using AFSK1200 or FSK 300 (for HF packet, transmit only), only for APRS data. For voice need to use USB OTG audio adapter or transceiver with built-in USB audio such as MCHF/IC-7x000, there is also support for USB CAT PTT control for these transeivers

 - **Loopback transport**, which records and plays your recorded voice back to test and evaluate different Codec2 modes and speech quality, could be enabled or disabled from Preferences, this mode is also activated if no USB/Bluetooth/TCPIP connection was made
 - **Voice level VU indicator**, display audio level on transmit or receive
 - **S-meter**, displayed only when KISS extensions are enabled and modem is able to send signal level information
