Tool/software:
Hi,
Customer is doing stability test, fast temp change between -40~85.
Zigbee protocol. ZR role.
if 30s network sync, the device's RF has issue to communicate. looks the PLL is unlocked based on the snapshot of Spectrum (right one is the issue happens). the M4F is still working well. after reset, all is recovered.
if 5s data transfer, almost works normally.
guess there is a temperature calibration/compensation mechanism? how to optimize it?
