This is great. I was wondering how to implement a TLS inside a STM32 without Embedded Linux or anything. Thanks!

Nice. Is there support for custom STM32 microcontroller boards? I noticed only Nucleo boards and discovery kits in the video. Thank you

@mongoose-networking-library Күн бұрын

The simplest way is to choose the board which is closest to yours, then modify. Join the chat, and we'll assist !

@mongoose-networking-library Thanks. I actually have an STM32F4 nucleo board but I plan on experimenting with the Mongoose wizard for a custom board. I haven't made up my mind on the exact STM32 MCU that I'll be using. IDE: STM32CubeIDE RTOS: FreeRTOS

Hi, I uploaded the code by adapting it to the STM32F746G-DISCO development board. I added Dashboard UI. I compiled it without any errors But when I ran it, it could not get an IP address from DHCP. Before adding Dashboard, it was getting an IP from DHCP and sending OK to the browser. You can see the data coming from the serial communication below. What could be the error?
