+	help
+	  Uses Zephyr's loramac-node-based LoRa driver for SX127x radios.
+	  Supports SX1272, SX1276, and SX1278 chips via the standard Zephyr
+	  LoRa API (lora_config, lora_send_async, lora_recv_async).
+
+	  Chip-specific features not available via standard API are stubbed:
+	    - Instantaneous RSSI (hwGetCurrentRSSI returns -80 dBm sentinel)
+	    - Preamble detection (always false — TX won't abort mid-preamble)
+	    - RX boost (no-op — SX127x has no dedicated boost register)
+	    - AGC reset (no-op — loramac-node manages AGC internally)
+	    - BUSY pin (false — SX127x has no BUSY signal)
+
+	  Used by: TTGO LoRa32, Heltec LoRa32 V1/V2, and any board with
+	  an SX1272/SX1276/SX1278 radio.
