BQ79616-Q1: Why don't stack devices wake up?

Part Number: BQ79616-Q1
Other Parts Discussed in Thread: BQ79616

Tool/software:

Hello,

I have BQ79616 stack devices controlled by BQ79600 UART. After sending a wake-up signal with STM32, I observed that the bridge device wakes up, but the stack devices do not. I suspect that there may be a problem with the daisy chain structure, causing the wake-up signal to not be transmitted properly. I can also read and write to the registers of the bridge device. What could be the reason for this?
