串行端口

I've gone through the code for the serial port service, and since it is set up with pointers that are shared between UART and SPS, I'm not sure the best way to send data from the app to a mobile device. For example, I'd like to send ASCII values from sensors periodically, but what is the best way to do this using the example code, should I be allocating my own pointers in memory and then calling app_uart_push()? Maybe a couple lines example code would help. Thanks!
