Property 0x5201. WB_RSQ_SNR_HI_THRESHOLD
Sets high threshold which will trigger the RSQ interrupt if the Audio SNR is above this threshold. The CTS bit (and
optional interrupt) is set when it is safe to send the next command. This property may only be set or read when in
powerup mode. The default is 127dB.
Default: 0x007F
Units: dB

Interrupt Source Enable: Audio SNR High.
Enable SNR high as the source of interrupt which the threshold is set by
WB_RSQ_SNR_HI_THRESHOLD.
Interrupt Source Enable: Audio SNR Low.
Enable SNR low as the as the source of interrupt which the threshold is set by
WB_RSQ_SNR_LO_THRESHOLD.
Interrupt Source Enable: RSSI High.
Enable RSSI high as the source of interrupt which the threshold is set by
WB_RSQ_RSSI_HI_THRESHOLD.
Interrupt Source Enable: RSSI Low.
Enable RSSI low as the source of interrupt which the threshold is set by
WB_RSQ_RSSI_LO_THRESHOLD.
