Meaning of serial output from ESP32

[AndrewJ]

Hi, all,
First post here. I'm from the UK and using a number of ESP32 boards (and also ESP8266's).
I'm running a micropython package on ESP32, and in between the expected output in the serial console I see a lot of messages like this...

Code: Select all

E (1820430) wifi: esf_buf: t=7 l=126 max:16, alloc:16 no eb

The number in brackets appears to be the time, it is different for each message.
The number after "l=" is sometimes 126 as shown in this example, and sometimes 1600.

I think it may be some kind of error message. What do all the parts mean, please?
Thanks in advance
AndrewJ

I am experiencing the same using ESP-WROOM-32, anybody got an idea of what this is and if we should be worried in a production scenario? I am using the Arduino framework.

Hi all,

This is the feedback I got on Github from the developers there.
