ESP8266 ESP-WROOM-02D

[UserApplied]

I am looking for information regarding my WROOM ESP-WROOM-02D module. I am trying to understand the following terminal output:

WS:ac

:rn 22
:rch 22, 5
:rch 27, 8
:rch 35, 22
:rch 57, 5
:rch 62, 8

I have created a program where I am listening for packets from a host, but sometimes the ESP does not respond. It won’t even process the packet in the handler function. I have enabled ESP CORE debug, and I noticed that the ESP is still alive, because even when the packets are not processed by the higher‑level function, the ESP still prints messages to the serial terminal.

Is there any documentation that explains each debug message for the different debug modes? I have only found basic reboot‑related descriptions, but the ESP CORE debug messages seem to be undocumented.
