Hi! I'm trying to estabilish connection between two discovery stm32f4 boards. Everything seems fine, I'm sending alway value of "0x01". First transmission is okay, but next is not receiving "0x01" but " 0x08 then 0x10 then 0x20, 0x40, 0x80 and then back to 0x01?

What 's the problem here? I tried flusing buffor nothing helps.
I'm coding in IAR.
