Function Documentation
◆ arq_modem_dequeue()
| bool arq_modem_dequeue | ( | arq_action_t * | action, |
| int | timeout_ms | ||
| ) |
Dequeue the next modem action (called from modem TX worker).
Blocks up to timeout_ms milliseconds waiting for an action.
- Parameters
-
action Output action. timeout_ms Wait timeout in milliseconds.
- Returns
- true if an action was dequeued, false on timeout.
◆ arq_modem_enqueue()
| int arq_modem_enqueue | ( | const arq_action_t * | action | ) |
Enqueue a modem action (called from FSM action callbacks).
- Returns
- 0 on success, -1 if queue full.
◆ arq_modem_preferred_rx_mode()
| int arq_modem_preferred_rx_mode | ( | const arq_session_t * | sess | ) |
Return the preferred RX FreeDV mode for the current session state.
- Parameters
-
sess Current session (read-only).
- Returns
- FREEDV_MODE_* constant.
◆ arq_modem_preferred_tx_mode()
| int arq_modem_preferred_tx_mode | ( | const arq_session_t * | sess | ) |
Return the preferred TX FreeDV mode for the current session state.
- Parameters
-
sess Current session (read-only).
- Returns
- FREEDV_MODE_* constant.
◆ arq_modem_ptt_off()
| void arq_modem_ptt_off | ( | void | ) |
Notify ARQ that PTT has gone OFF.
◆ arq_modem_ptt_on()
| void arq_modem_ptt_on | ( | int | mode, |
| size_t | frame_size | ||
| ) |
Notify ARQ that PTT has gone ON.
- Parameters
-
mode FreeDV mode of the frame now on air. frame_size Frame size in bytes.
◆ arq_modem_queue_init()
| int arq_modem_queue_init | ( | size_t | capacity | ) |
Initialise the action queue.
- Parameters
-
capacity Maximum number of pending actions.
- Returns
- 0 on success, -1 on allocation failure.
◆ arq_modem_queue_shutdown()
| void arq_modem_queue_shutdown | ( | void | ) |
Flush and destroy the action queue.
◆ arq_modem_set_event_fn()
| void arq_modem_set_event_fn | ( | void(*)(int mode, bool ptt_on) | fn | ) |
Register the PTT event injection function (called from arq.c init).
- Parameters
-
fn Callback: mode >= 0 and ptt_on=true → TX_STARTED; ptt_on=false → TX_COMPLETE.
