GlassOnTin	09d1f6409f	Add R-Watch (T-Watch Ultra) board support with LoRa, GPS, PMU, RTC, and deep sleep ... Board definition (BOARD_TWATCH_ULT = 0x45) for LilyGo T-Watch Ultra with verified pin mapping from LilyGoLib hardware docs. Working subsystems: - SX1262 LoRa radio: online at 868 MHz, tested with rnsd/Reticulum - AXP2101 PMU: all power rails configured, battery monitoring, charging - MIA-M10Q GPS: UART at 38400 baud, TinyGPSPlus NMEA parsing - PCF85063A RTC: time read/write, GPS sync infrastructure - XL9555 GPIO expander: I2C driver, LoRa antenna switch - BLE: initialized, KISS protocol responsive - Deep sleep: button wake (PMU IRQ GPIO 7), timer wake for beacon - Beacon sleep cycle: periodic wake for GPS beacon TX in standalone mode New files: - VISION.md: R-Watch product vision document - XL9555.h: minimal I2C GPIO expander driver - CO5300.h: QSPI AMOLED display driver (not yet functional) Display driver (CO5300.h) is written but disabled (HAS_DISPLAY=false). QSPI init succeeds but pixel writes don't reach the display controller. Suspected XL9555/BHI260AP GPIO expander pin mapping issue under investigation.	2026-03-27 12:18:46 +00:00
GlassOnTin	033ddd6757	Add GPS beacon and LXMF telemetry for T-Beam Supreme and Heltec V4 ... Standalone GPS beacon mode: when no KISS host is connected for 15s, the RNode transmits position and battery telemetry over LoRa. Two beacon paths: - LXMF (recommended): encrypted per-packet messages with announces, compatible with Sideband and any LXMF application. Supports IFAC network authentication. - Legacy JSON: plaintext or encrypted raw packets for simple collectors. Key changes: - GPS support for T-Beam Supreme S3 (L76K) and Heltec V4 (external) - SX1262 radio fixes: IQ polarity, DCD preamble lockup, RX reliability - LXMF identity management with NVS-backed Ed25519/X25519 keys - IFAC authentication (CMD_IFAC_KEY 0x89) for private networks - Per-channel serial isolation (USB, BLE, WiFi) - GPS status page in OLED display rotation - Provisioning via rnlog: provision-lxmf, provision-ifac - Documentation in Documentation/BEACON.md	2026-03-12 17:01:29 +00:00
