Hello,
we have a 7002 module working on our custom 5340 board. It can connect to our 2.4 GHz network and perform some initial network tests.
I am getting net_pkt errors and net_con warnings periodically after it has made a connection to our access point and is just maintaining the connection.

The memory allocation settings in our .conf file are:
CONFIG_NET_TX_STACK_SIZE=4096
CONFIG_NET_RX_STACK_SIZE=4096
CONFIG_NET_MGMT_EVENT_STACK_SIZE=2048
CONFIG_HEAP_MEM_POOL_SIZE=153600
CONFIG_MAIN_STACK_SIZE=4096
CONFIG_SHELL_STACK_SIZE=4096
CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=2048
We do not have any applications that are trying to send or receive IP messages using the stack, any activity would be normal Wi-Fi AP actions or maybe the DHCP client.
How should I resolve these log warnings and errors?
BR
