Property 0x5202. WB_RSQ_SNR_LO_THRESHOLD
Sets low threshold which will trigger the RSQ interrupt if the Audio SNR is below 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 0dB.
Available in: All
Default: 0x0000
Units: dB
Step: 1
Range: 0-127

Property 0x5203. WB_RSQ_RSSI_HI_THRESHOLD
Sets high threshold which will trigger the RSQ interrupt if the RSSI 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.
