How APRS Connect talks to real radios on Android — Bluetooth, BLE, and USB KISS TNCs, an AFSK audio modem, KISS over TCP, and APRS-IS, in any combination.

Connect APRS Connect to a Bluetooth Classic KISS TNC on Android — Kenwood TH-D74 and TH-D75, Mobilinkd TNC3, pairing, KISS mode, and troubleshooting.

Connect APRS Connect to a Bluetooth Low Energy KISS TNC on Android — Mobilinkd TNC4 in LE mode, B.B. Link, scanning, and why a BLE TNC never appears in the paired list.

Plug a KISS TNC into your Android phone's USB-C port with an OTG cable — the permission prompt, baud rate, and the DTR setting some radios need.

Use any radio for APRS with no TNC at all — the app's built-in AFSK 1200 software modem encodes and decodes packet audio through a cable to the radio.
