Tested with both our fork AND upstream RNode firmware — neither can receive LoRa packets on this T-Beam Supreme unit. TX works (14KB transmitted via rnsd), noise floor measured (-86 dBm), airtime detected from watch beacon, but RX_DONE interrupt never fires. Decoded packets = 0 in all tests. The watch beacon firmware is verified correct: - IFAC crypto: all 4 tests PASS (Python round-trip verified) - Packet format: byte-for-byte match with Python IFAC apply - IFAC key: stored correctly in NVS, matches computed value To verify the beacon end-to-end, a working RNode receiver is needed (different T-Beam unit, Heltec, or the GL.inet's RNode brought within range).

"""Compute the ESP32 partition hash for an RNode firmware binary.
|
|
|
|
The ESP32 build toolchain appends a SHA256 hash to firmware binaries.
|
|
esp_partition_get_sha256() returns this embedded hash (the last 32 bytes).
|
|
This is different from sha256sum of the entire file.
|
|
|
|
Usage:
|
|
python3 get_partition_hash.py <firmware.bin>
|
|
|
|
# Flash and set hash:
|
|
python3 get_partition_hash.py build/esp32.esp32.esp32s3/RNode_Firmware.ino.bin
|
|
rnodeconf -H <output_hash> /dev/ttyACM0
