Every time 001-m17 sends data, you need to press "Ctrl + enter". Which function of "wireless—UART" does "Ctrl + enter" correspond to? How to remove this restriction?
The Wireless UART example expects to receive an ASCII char from Tera Term to send it Over the Air. In code, this is handled with CallBacks (Uart_RxCallBack, UartStreamFlushTimerCallback, BleApp_FlushUartStream).
The BleApp_FlushUartStream collects the data from the serial manager, and then, sends it Over the Air.
Hope this makes sense
