Part Number: CC2652R
Hi,
A customer uses one CC2652 launchpad as the coordinator and another one as end device with example code doorlock, the coordinator tries to unlock the door every 20 seconds, they found sometimes the coordinator didn't send the "Unlock" command.
According to the sniffer, "Frame Pending" bit is set to be 1 in ACK to Data Request, but the coordinator didn't send the "Unlock" command.
On the channel 14 they are using, there is strong interference from Wi-Fi.
If switching to another clean channel, the coordinator works well.
As "25.5.4.1.5 CCA Monitoring" of http://www.ti.com/lit/ug/swcu185d/swcu185d.pdf, if ccaEnEnergy = 0 and ccaEnCorr = 0 and ccaEnSync = 0, then ccaState = IDLE. In the latest ZNP project in v3.30.00.03 SDK, ccaEnEnergy, ccaEnCorr and ccaEnSync are set to be 0 by default.
Does it mean it's always CCA idle? Please advise how to modify the relevant parameters to improve. Thanks!
Regards,
Yonghua
