When using normal transmit on UART i can send a message from a router to a coordinator without no issue
HAL_UART_Transmit(&huart2, (uint8_t*)xFrame, sLen,100);
, but when i try to send it using
HAL_UART_Transmit_DMA(&huart2, (uint8_t*)xFrame, sLen);
while (xUartReady != SET)
xUartReady = RESET;
The xUartReady is handled in the callback function.
Did any of you had this issue? How it was solved?
