STM32F767ZI MQTT Issue

[Dawid Żądło]

Hi all,

I have issue with stm33f767zi and LWiP mqtt. I'm trying to send data over mqtt every 10ms. Data is 400 samples from 3 ADCs represented as cJSON. After sending a few packets Im getting hardfault on tcp_out(), but if I set interval to 100ms every thinks works just fine. Could you suggest me what should I check in my configuration?

Thanks in advance

Hi, I have a similar project, and I can't achieve stable operation even for 1 second! Here, I asked a question... https://community.st.com/t5/stm32-mcus-products/what-are-the-potential-causes-cab-be-when-combining-the-mqtt/m-p/662077#M241065
