mbed OS V5 BLE UARTService to USB/UART PassThru Example

Moxon Design : mbed OS V5 BLE UartService to USBUART passthru example

This example will advertise on BLE as "BLART" and allow BLE serial echo to the USB Serial port. Open a Bluetooth terminal application, like Nordic "nRF UART" and connect to "BLART", open a terminal emulator program, like "TeraTERM", and connect to the USB COM Port (like JLink CDC UART Port), and echo characters back and forth. Set UART_LoopBack = 1 for local loopback (e.g. BLE to BLE, USB-UART to USB-UART)

moxondesign 0:2d1d68397ff7 2
moxondesign 0:2d1d68397ff7 3 This guide reviews the steps required to get Blinky working on an mbed OS platform.
moxondesign 0:2d1d68397ff7 4
moxondesign 0:2d1d68397ff7 5 Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).
moxondesign 0:2d1d68397ff7 6
moxondesign 0:2d1d68397ff7 7 ## Import the example application
moxondesign 0:2d1d68397ff7 8
moxondesign 0:2d1d68397ff7 9 From the command-line, import the example:
moxondesign 0:2d1d68397ff7 10
moxondesign 0:2d1d68397ff7 11 ```
moxondesign 0:2d1d68397ff7 12 mbed import mbed-os-example-blinky
moxondesign 0:2d1d68397ff7 13 cd mbed-os-example-blinky
moxondesign 0:2d1d68397ff7 14 ```
moxondesign 0:2d1d68397ff7 15
moxondesign 0:2d1d68397ff7 16 ### Now compile
moxondesign 0:2d1d68397ff7 17
moxondesign 0:2d1d68397ff7 18 Invoke `mbed compile`, and specify the name of your platform and your favorite toolchain (`GCC_ARM`, `ARM`, `IAR`). For example, for the ARM Compiler 5:
moxondesign 0:2d1d68397ff7 19
moxondesign 0:2d1d68397ff7 20 ```
moxondesign 0:2d1d68397ff7 21 mbed compile -m K64F -t ARM
moxondesign 0:2d1d68397ff7 22 ```
moxondesign 0:2d1d68397ff7 23
moxondesign 0:2d1d68397ff7 24 Your PC may take a few minutes to compile your code. At the end, you see the following result:
moxondesign 0:2d1d68397ff7 25
moxondesign 0:2d1d68397ff7 26 ```

moxondesign 0:2d1d68397ff7 73 ## Troubleshooting
moxondesign 0:2d1d68397ff7 74
moxondesign 0:2d1d68397ff7 75 1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`
moxondesign 0:2d1d68397ff7 76
moxondesign 0:2d1d68397ff7 77 ```
moxondesign 0:2d1d68397ff7 78 mbed --version
moxondesign 0:2d1d68397ff7 79 ```
moxondesign 0:2d1d68397ff7 80
moxondesign 0:2d1d68397ff7 81 If not, you can update it:
moxondesign 0:2d1d68397ff7 82
moxondesign 0:2d1d68397ff7 83 ```
moxondesign 0:2d1d68397ff7 84 pip install mbed-cli --upgrade
moxondesign 0:2d1d68397ff7 85 ```
moxondesign 0:2d1d68397ff7 86
moxondesign 0:2d1d68397ff7 87 2. If using Keil MDK, make sure you have a license installed. [MDK-Lite](http://www.keil.com/arm/mdk.asp) has a 32 KB restriction on code size.
