Can't enter deep-sleep mode due to fault

[seanli]

Hi everyone,

I am using ESP32-PICO-Kit to evaluate AT command application (ESP32-PICO-D4 AT Bin V2.0). I followed the instruction, successfully downloaded the bin and connected to my test AP. When I try to enter deep-sleep mode using AT+GSLP=1000, I got the error below.

Is there any configuration needed before entering deep-sleep mode? I went through esp32_at_instruction_set_and_examples but didn't find any special things. Any clue to diagnose this problem? Thanks in advance.
