Detailed Description

SX1262 implementation of RadioDriver.

Manages the SX1262 via opcode‑based SPI using the SpiAccess interface. Configures the chip in FSK mode with software CRC‑CCITT to match the IO‑Homecontrol protocol (the SX1262 lacks the SX1276's IoHomeOn mode). The IRQ-driven RX/TX orchestration is inherited from SoftPhyDriverBase; this class supplies the SPI transport and every SX1262-specific register/opcode encoding underneath it.

Todo
Confirm whether additional SX1262 board variants need board-specific FEM defaults beyond the currently documented Heltec V3/V4 assumptions.

Member Function Documentation

◆ apply_tuning()

void esphome::home_io_control::RadioSX1262::apply_tuning ( const TuningConfig & tuning)
inlineoverridevirtual

Apply SX1262 runtime tuning: RX bandwidth, response preamble, post-TX settle delay.

Reimplemented from esphome::home_io_control::RadioDriver.

Definition at line 135 of file radio_sx1262.h.

Here is the call graph for this function:

◆ apply_tx_modulation_workaround_()

void esphome::home_io_control::RadioSX1262::apply_tx_modulation_workaround_ ( )
protected

Apply the Semtech TX modulation-quality erratum workaround (datasheet §15.1).

The datasheet requires it "before any packet transmission", so it hangs off before_tx_arm rather than running once at init — same placement rationale as RadioLR1121's high-ACP workaround.

Definition at line 223 of file radio_sx1262.cpp.

Here is the call graph for this function:

◆ before_tx_arm()

void esphome::home_io_control::RadioSX1262::before_tx_arm ( )
inlineoverrideprotectedvirtual

Hook run immediately before every SetTx.

No-op by default; LR1121 overrides this to apply its high-ACP TX-quality workaround, which Semtech's own reference applies unconditionally before every SetRx/SetTx.

TX modulation-quality erratum (SX1262_REG_TX_MODULATION): the datasheet requires bit 2 be set for every (G)FSK transmission, so it is re-asserted before each SetTx rather than assumed to survive from init.

◆ clear_irq_status()

void esphome::home_io_control::RadioSX1262::clear_irq_status ( uint32_t irq_mask)

Parameters
irq_maskBitmask of IRQs to clear (each driver narrows to its own IRQ word width).

Here is the call graph for this function:

◆ configure_buffer_base()

void esphome::home_io_control::RadioSX1262::configure_buffer_base ( )
overrideprotectedvirtual

Hook run as part of reset_rx_state_, before re-entering RX.

No-op by default; SX1262 overrides this to (re-)write its buffer base address, which LR1121 doesn't need.

SX1262's buffer base addresses (TX=0x00, RX=0x80) are re-asserted on every RX reset — LR1121 has no equivalent register.

◆ discovery_hop_slice_ms()

uint16_t esphome::home_io_control::RadioSX1262::discovery_hop_slice_ms ( const TuningConfig & tuning) const
inlinenodiscardoverridevirtual

Per-channel dwell while pairing discovery hops (SX1262).

SX1262 frequency changes require a standby→SetRfFrequency→RX cycle (no fast hop), so discovery needs a much longer dwell than the SX1276. The value comes from the user-facing sx1262_discovery_hop_slice_ms tuning field.

Implements esphome::home_io_control::RadioDriver.

Definition at line 150 of file radio_sx1262.h.

◆ dump_debug()

Reimplemented from esphome::home_io_control::RadioDriver.

Definition at line 277 of file radio_sx1262.cpp.

Here is the call graph for this function:

◆ early_rx_read_offset()

int16_t esphome::home_io_control::RadioSX1262::early_rx_read_offset ( ) const
inlinenodiscardoverrideprotectedvirtual

Data-buffer offset an in-flight reception is being written to, or a negative value when this chip must not be read before RX_DONE.

Neither chip's RX_DONE marks the end of the frame: with no hardware framing, RX runs in fixed-length mode at SOFT_PHY_RX_PROBE_PACKET_LEN, so RX_DONE arrives a fixed ~10 ms after the sync word no matter how short the frame actually was. That delay lands squarely on the protocol's tightest turnaround — the hub's reply to a device's challenge — so a driver that can read its buffer while reception is still running opts in here and the shared flow finishes on the frame's own air time instead (see try_early_completion_).

Default is -1: wait for RX_DONE exactly as before. SX1262 overrides it with the RX base address it programs in configure_buffer_base(), which is where a single in-flight packet always starts. LR1121 is left on the RX_DONE path pending hardware validation.

The SX1262 writes demodulated bytes into its data buffer as they arrive, and a single in-flight packet always starts at the RX base address programmed by configure_buffer_base(), so the shared flow can read the frame out on its own air time rather than waiting the fixed ~10 ms for the 48-byte RX_DONE.

Reimplemented from esphome::home_io_control::SoftPhyDriverBase.

Definition at line 251 of file radio_sx1262.h.

◆ exchange_wait_slice_ms()

uint32_t esphome::home_io_control::RadioSX1262::exchange_wait_slice_ms ( ) const
inlinenodiscardoverridevirtual

Per-channel dwell while waiting for exchange responses (SX1262).

Longer than the protocol baseline; rationale is documented at SX1262_EXCHANGE_RESPONSE_WAIT_SLICE_MS.

Reimplemented from esphome::home_io_control::RadioDriver.

Definition at line 144 of file radio_sx1262.h.

◆ fill_capture_info()

void esphome::home_io_control::RadioSX1262::fill_capture_info ( bool blocking_wait,
uint32_t irq_status,
uint8_t rx_offset,
uint8_t reported_len,
const uint8_t * raw,
uint8_t raw_len,
const uint8_t * frame,
uint8_t frame_len )
overrideprotectedvirtual

Populate the RadioCaptureInfo from chip-specific telemetry (RSSI opcode, packet-status byte, and IRQ-word-width narrowing all differ per chip).

Note: crc_error is set from the CrcErr IRQ bit — unlike the SX1276, this driver sees and reports frames with a bad CRC.

◆ has_fast_tx_rx_turnaround()

bool esphome::home_io_control::RadioSX1262::has_fast_tx_rx_turnaround ( ) const
inlinenodiscardoverridevirtual

TX→RX turnaround capability (SX1262): slow.

The TX→standby→RX transition plus the post-TX settle delay is too slow to catch a device's immediate reply through the standard exchange wait; in pairing, the key-confirm (0x33) is missed that way. PairingEngine therefore uses its dedicated key-confirm wait with key-init re-trigger on this driver.
