BC660K-GL can not wakup by MQTT packet

IoT Modules LPWA Module

I have replaced BC66NB-04-STD by BC660K-GL in our device recently. DRX function works well on BC66. I can wake our device up via MQTT command, and the average latency is usually 5~10 sec. But on BC660K. I can’t wake up our device until it sends its ALIVE uplink packet. Has anyone encountered the same problem? I would be very grateful if you could help me solve this problem.
