CC3351: Cetiication of ETSI 2.4G Adaptivity SCST Fail for CC33xx R1.0.0.8

Part Number: CC3351


Tool/software:

Dear Sirs:

  We are using CC33XX-LINUX-MPU R1.0.0.8

And the certification lab respond with the ETSI 2.4G Adaptitivity SCST fail in CH1_2412MHz_11b.

By using the default CC33XX R1.0.0.8 configuration inside the release, the test can only be passed when the unwanted signal reaching -67dbm.

By creating the cc33xx_conf.bin from cc33conf_src/cc33xx-conf_ETSI.ini, the test can only be passed when the unwanted signal reaching -64dbm.

Both of the signal strength are already over the pass criteria -70dbm. And even adding minimum gain 1.4dbm, it still over the pass criteria.

In other vendor chips, there are some parameters like ED threshold or CCA that can be set to help passing the certification.

Does TI have any parameters that is undocumented and can be used to pass the Certification.

I see the CCA has parameter inside acx but it is not used inside the driver.

1. I would like to know whether TI has already pass the FCC/ETSI or not?

2. Does TI have any other way that can change the ED/CCA during certification?
