FRDM-MCXW72: AN14889 Sensitivity test

[Marcon]

Hello,

I am following the steps in the AN14889 to run sensitivity tests on  FRDM-MCXW72 but without success

I use the following sequence to run the test on channel 0 (2402 MHz).
Could you check it?

Connectivity Test Interface short cuts
------------------------------------------
-Press [t] for Tx operation
-Press [r] for Rx operation
-Press [z] to increase mode (GENFSK, BLE) and rate
-Press [x] to decrease mode (GENFSK, BLE) and rate
-Press [c] to toggle between fixed or per channel whitening (for BLE only)
-Press [q] for channel up
-Press [w] for channel down
-Press [a] for Power up
-Press [s] for Power down
-Press [n] to increase the Payload
-Press [m] to decrease the Payload
-Press [d] to increase the XTAL Trim value
-Press [f] to decrease the XTAL Trim value
These keys can be used all over the application to change
the test parameters

Average Rssi during PER: 0 dBm
Received 0 of 0 packets transmitted

Press [ENTER] to go back to the Per Rx test menu

I use a BLE tester to send the standard BLE test packets but the board doesn't receive any packet.
The application note does not specify any setting for the sensitivity test.

On the other hand if I use hci_bb application and standard HCI commands, the board gets stuck randomly at all PHY only when the tester sends the HCI_LE_RECEIVER_TEST or HCI_LE_ENHANCED_RECEIVER_TEST make it impossible to run the tests.
The transmitter test command works flawlessly.

Could you give me some advices?
I am using SDK_26_06_00_FRDM-MCXW72.

Thanks,
Marco
