I wanted to see if the bno055 sensor is ready and set the PB8, PB9 pins as SDA, SCL. (my mcu = stm32f334r8)connectionsSDA_pin -> SDA pin sensorSCL_pin -> SCL pin sensorVCC -> VCCGND -> GNDbut the variable is never HAL_OKthanks for answer.

I am doing xbee communication with stm32, I am sending and receiving data, there is no problem, but I cannot see message on the serail monitor of stm32. (but it appears in debug process) why?
