STM32F10xx SPI UART conflict

ABouk

Good morning everyone,

I was trying to establish communication via UART1 - UART2 - SPI1, everything is fine until i use "HAL_SPI_TransmitReceive(...)" and suddenly UART1 and UART2 are locked (i can visualize both those "UART_HandleTypeDef" in my Expression window ...

After that i cannot use HAL_UART_Transmit(...) because it returns HAL_BUSY ....

Can someone help me please ?
