I am trying to post data using MQTT in LWIP drivers. I am able to bring up the ethernet connection, can ping from PC to STM32F767 device as well. Tried to connect to MQTT broker. When publishing message I get an error as follows:-
tcp_write : could not allocate memory for pbuf copy size 88
mqtt_output_send: Send failed with err -1 ("Out of memory error.")
Why am I getting this error?
