When you look into the schematics of the BLE Pioneer board you will see that the UART-Tx pin is now on P1_4. When you change that, the USB-UART bridge will work again.
Thank you sir
Sir sorry to bother you. now I connected Pin P0.5( UART TX) to the pin P1.4 but still I am not getting required output.
and also sir In my one of serial data transfer project i connected pin P0.5 (UART TX) to pin P1.5 the it was giving output but now I added BLE then output is gone .
OK, too many assumptions and misleads due to language barrier (I am not natively English).
UART_TX_STS_FIFO_EMPTY is a constant != 1 so the if will always fail.
UART_PutString() is blocking and waits for the buffer to be free, so there would be no need to wait for an empty UART. If you want to wait better use the appropriate API to get the status and AND (&) the result with UART_TX_STS_FIFO_EMPTY.
Sorry to bother you again. sir I want to to transfer many motion sensors data one by one using UART of PSOC 4 to the UART of other board. So please guide me for this....
You have to write a "Protocol" that assumes a controlled data flow. When you transfer printable ASCII characters only you need a conversion on both sides, but you are able to work with "Message Blocks" These blocks (as a suggestion only) consist of
Sensor Number ('00" to "99"
Sensor Data (fixed number of digits)
Message delimiter (\n or \r)
