QCA9300 → QCA9300: RX fails with RxSBasicSegment cannot parse the segment with version v256
Summary
I have two UP Squared boards (Board A and Board B), each with two Wi-Fi NICs:
- Intel AX210
- Qualcomm Atheros AR93xx / QCA9300
Test scenarios:
| Scenario |
Result |
| AX210 → AX210 (injector on TX board, logger on RX board) |
✅ Works correctly |
| QCA9300 → QCA9300 (injector on TX board, logger on RX board) |
❌ TX seems OK, but RX fails with repeated parsing errors |
Error message on RX:
RxSBasicSegment cannot parse the segment with version v256.. Error skipped
Hardware
- Board A: UP Squared + Intel AX210 + Qualcomm Atheros AR93xx (QCA9300)
- Board B: UP Squared + Intel AX210 + Qualcomm Atheros AR93xx (QCA9300)
Both machines show the same PCI devices:

Scenario 2 — QCA9300 → QCA9300 ❌ (failing)
Channel config: 2417 MHz, HT20 — Format: HT, MCS 0
TX — Board B (QCA9300 injector)
PicoScenes -d debug -i 1 --channel "2417e6 20e6 2417e6" \
--mode injector --repeat 500 --delay 10000 \
--format HT --mcs 0
The injector prints TxFrame debug output, so transmission appears to be happening normally.
RX — Board A (QCA9300 logger)
PicoScenes -d debug -i 1 --channel "2417e6 20e6 2417e6" \
--mode logger --output captura
Actual output (repeated):
Error occurs during Rx frame parsing: RxSBasicSegment cannot parse the segment with version v256.. Error skipped
Question
Could you help identify what might cause the QCA9300 RX parsing to fail with segment version v256?
Any suggested parameters, recommended QCA9300 logging mode, or extra diagnostics to collect are very welcome. Thank you!
