CCA Threshold #148

Open jeter1112 opened 6 years ago

jeter1112 commented 6 years ago

Hi, I wanted to change the CCA threshold of ar9271. I modified the ar9002_phy.h.

_#define AR_PHY_CCA_NOM_VAL_9271_2GHZ -20

define AR_PHY_CCA_MIN_GOOD_VAL_9271_2GHZ -27

define AR_PHY_CCA_MAX_GOOD_VAL_92712GHZ -16

However, it seems nothing to happen. I want to know how to change CCA threshold correctly.

Hi,

Thats for NF calibration. There's a separate CCA register which programs in the noise floor value. It's done in the PHY init path.

Which register represents CCA register?

@jeter1112 Not sure if it's still relevant for you, but here is a patch that allows for changing the threshold via module parameter: https://github.com/bortek/EZ-WifiBroadcast/blob/develop/kernel/linux-4.9.28-ath9k_htc-misc.patch
