Re: #mqtt Failed to obtain RX buffer #mqtt #api

Hi Erik,

you are running out of RX network buffers. Try to increase the value of
CONFIG_NET_BUF_RX_COUNT
and optionally
CONFIG_NET_PKT_RX_COUNT
options.

Cheers,
Jukka

Hi,

I'm implementing mqtt on an nucleo stm32 board (stm32f767zi). The
communication from the broker seemed to work OK at first, however
when stressing the communication a bit the next error appears
multiple times in the log:
==> "<err> eth_stm32_hal: Failed to obtain RX buffer".

What can be the cause of this?

Kind regards
