| So the response above indicates that the RSSI value is '''-75 dBm''' (because that's what 19 represents since it falls in the 2..30 range) and the channel bit error rate is '''Not known or not detectable''' (because that's what 99 represents). | | So the response above indicates that the RSSI value is '''-75 dBm''' (because that's what 19 represents since it falls in the 2..30 range) and the channel bit error rate is '''Not known or not detectable''' (because that's what 99 represents). |
