nRF54L15-DK: Periodic "rx failed error" (1, 2, 9) in 802154_phy_test example

[yong0]

Hello, I am currently experiencing an issue with the 802154_phy_test example on the nRF54L15-DK board, and I would appreciate your technical support.

[ Environment ]

- Hardware: nRF54L15-DK

- SDK: nRF Connect SDK v3.3.0

- Toolchain: nRF Connect SDK Toolchain v3.3.0

- Application: 802154_phy_test example (Default configuration)

[ Symptom / Problem ]

When running the example without modification, the following error messages are continuously printed on the console log:

- "rx failed error 1!" - "rx failed error 2!" - "rx failed error 9!"

[ Additional Context ]

- The errors appear randomly without any specific pattern or constant period.

- To rule out any RF interference or multi-path fading from the surrounding environment, we conducted a test in the middle of a wide-open soccer field. However, the exact same errors occurred.

- We have not modified the core PHY test source code. Could you please provide insight into what causes these specific error codes (1, 2, and 9) during RX operations? Any suggestions on how to debug or resolve this issue would be highly appreciated. Thank you.

Hi

Sorry that this took so long to get back to you on, but we've been short on staff for the month of July, and haven't gotten to this issue until now.

The 802154_phy_test sample is set to RX here, so it listens to all transmissions. The error log "rx failed error 2!" means the radio received on-air data with an incorrect CRC (usually caused by noise). The preamble matches IEEE 802.25.4, but the data is rejected due to a checksum error). You may also see rx failed error 3!, caused by communication between two other devices - the data is not addressed to your DK (incorrect address). This is expected and does not cause a crash.

Regarding the specific issue you're seeing, we've not been able to reproduce it on our end. Did you run a "west update" command on your end?

Best regards,

Simon
