v0.2.0-alpha.1
8c79b16

Prerelease: not yet run on a radio. The app passes its host tests: its own code, compiled for a PC, against a model of the firmware's API and of the radio's audio path. Try it on the bench first, with a dummy load or on a free frequency.

KISS TNC 0.9 from F4HWN v6.3.0 plus three extensions, all opt-in or invisible to a host that does not use them (APRSdroid works as before):

  • ACKMODE (G8BPQ, KISS 0x0C): the host sends C0 0C hi lo <frame> C0, the app answers C0 0C hi lo C0 once the frame has left the TNC. AXLink uses it with -profile f4hwn-kisstnc-ackmode.
  • Host frames lost: a frame from the host that arrives while another waits for the channel is counted in lost N (line 3).
  • USB reset: a frame cut off by a USB re-enumeration (RF on the cable at key-up) or a lapped receive ring is dropped instead of being sent on air truncated.

Install: F4HWN Labs v6.3.0 on the radio. Unzip AXLinkTNC-v0.2.0-alpha.1.zip (GitHub does not accept .app files as release assets), then in UV Studio: Apps → Community → Install a .app → AXLinkTNC.app. On the radio: F + 7, AXLink TNC, MENU.

Built by CI with the ARM GNU Toolchain 13.3.rel1 (as F4HWN builds): 3,812 B of the 4 KiB overlay.
