Appendix E - Stationary disturbance detection
In Enhanced ShockBurst™ it is recommended to use the Carrier Detect functionality only when the PTX
device does not succeed to get packets through, as indicated by the MAX_RT IRQ for single packets and by
the packet loss counter (PLOS_CNT) if several packets are lost. If the PLOS_CNT in the PTX device indi-
cates a high rate of packet losses, the device can be configured to a PRX device for a short time (T

CD-filter delay = 130µs+128µs = 258µs) to check CD. If CD was high (jam situation), the frequency channel
should be changed. If CD was low (out of range or jammed by broadband signals like WLAN), it may con-
tinue on the same frequency channel, but you must perform other adjustments (a dummy write to the
RF_CH clears the PLOS_CNT).
