Topic: Freertos stm32f439
Hi i am struggling with some configurations issues.
I am using the STM32CcubeMx and like to have an Freertos, lwip and wolfssl as my setup. I basically left all in it's default. Tried a client connection but failed. It's hard to figure out the correct setting in multiple header files and here to set callbacks.
My debug error
Your IO Send callback is null, please set
wolfSSL Leaving SendClientHello, return -308
wolfSSL error occurred, error = -308
wolfSSL Leaving wolfSSL_negotiate, return -1
wolfSSL Leaving wolfSSL_write, return -1
