Hi,
I am trying to read a value form a barcode scan using UART and the RX pin on the CY8CKIT-042-BLE (PSoC 4 BLE). The following is my code (modified from the HID Keyboard Example, as the goal is to send the value of the scan to a device, emulating a keyboard). I am unable to get any results from the scan to output on a PuTTY terminal. Any ideas on what I am doing wrong?
int main()
{
uint32 rxData;
CyGlobalIntEnable;
#if (DEBUG_UART_ENABLED == ENABLED)
UART_DEB_Start();
#endif /* (DEBUG_UART_ENABLED == ENABLED) */
DBG_PRINTF("BLE HID Keyboard Example Project \r\n");
Disconnect_LED_Write(LED_OFF);
Advertising_LED_Write(LED_OFF);
CapsLock_LED_Write(LED_OFF);
/* Start CYBLE component and register generic event handler */
CyBle_Start(AppCallBack);
WDT_Start();
#if (BAS_MEASURE_ENABLE != 0)
ADC_Start();
#endif /* BAS_MEASURE_ENABLE != 0 */
while(1)
{
/* CyBle_ProcessEvents() allows BLE stack to process pending events */
CyBle_ProcessEvents();
/* To achieve low power in the device */
LowPowerImplementation();
rxData = UART_DEB_UartGetChar();
if(rxData)
{
UART_DEB_UartPutChar(rxData);
}
.......
Thanks in advance,
Ryan

If you didn't setup your UART for interrupting the low power modes, then it won't wake up upon receiving UART data.
As a test, try commenting out the LowPowerImplementation(); and see if the unit starts echoing the data properly, if so, then it is the lower power mode not being setup correctly to allow UART wakeup/checking.
