What's new in v0.7.0

Wire-protocol additions (sector-array integration set)

Backwards-compatible — pre-v0.7 hosts work against v0.7 firmware and vice
versa; the new commands are simply skipped if unknown.

  • CMD_RADIO_STANDBY (0x40) / CMD_RADIO_RESUME (0x42) — host-driven radio gating
  • CMD_SET_DISPLAY_NAME (0x48) — sector name banner on the T114 TFT
  • CMD_SET_AUTO_CAD (0x4A) — auto-CAD before every TX, persisted in NVS on T114
  • CMD_ENTER_BOOTLOADER (0x74) — drop nRF52 into Adafruit DFU mode
  • CMD_LOG_MSG (0x80) — async log line (modem → host)
  • In-app OTA over the transport: CMD_OTA_BEGIN / CHUNK / VERIFY / APPLY / ABORT (0x90 / 0x92 / 0x94 / 0x96 / 0x98) — required path for T114 since it has no Wi-Fi

fw_suffix rename (aligns with pymc_sector_array OTA scanner)

CMD_GET_VERSION / VERSION_RESP now report:

  • Heltec T114: v0.7.0-heltec_t114 (renamed from t114)
  • ESP32-P4-Nano: v0.7.0-esp32_p4 (renamed from esp32p4)

This lets pymc_sector_array auto-detect the board from an uploaded .bin
during OTA — previously these two boards fell through the matcher.

Heltec T114 pymc_usb-v0.7.0-heltec_t114.hex + -dfu.zip nRF52840 + SX1262 + TFT 135×240; no Wi-Fi/TCP — USB-CDC + UART only

Flashing

ESP32 boards (USB CDC):

esptool.py --port /dev/ttyACM0 write_flash 0x10000 pymc_usb-v0.7.0-<board>.bin
# or, with PlatformIO source checkout:
cd firmware && pio run -e <env> -t upload

Heltec T114 (nRF52840 with Adafruit bootloader): double-tap reset to
enter DFU, then either drag the .uf2 (if you build one from the hex)
or use adafruit-nrfutil:

adafruit-nrfutil dfu serial -pkg pymc_usb-v0.7.0-heltec_t114-dfu.zip -p /dev/ttyACM0 -b 115200

Lilygo T3-S3 is the tightest (86% flash used); consider partition table
adjustments before adding ~150 KB more features on that target.
