External sensor commands: Add sensor ID to command: In the previous version a command was send without information regarding the target sensor. To have the possibility in future to e.g. calibrate a specific sensor, the sensor ID is now transmitted together with the command. As example in the new implementation the O2 Sensor selected in the sensor menu will blink to enable sensor identification.

# How to Create From Scratch a Project for _CPU2-RTE_ Code #

Follow the same procedure than for [CPU1](Detailed CPU1-Discovery Project.md), with changes:

- Create a new _board_ for processor:  
>   Series: `STM32F4`  
>   Mcu: `STM32F411xE`  
>   Debug: `JTAG`  

- Add `Small_CPU` linked source directory (instead of _Discovery_)

- Use linker script `OSTC4/Small_CPU/CPU2-F411.ld`
