Bootloader improve init sequence: Initialization of the BT module failed with the previous version. Root cause could be that the commands were send to fast to the module and the error counter expired before the configuration was stored. To avoid this problem a timer has been added which delays the transmission of commands by 100ms.

# How to Create From Scratch a Project for _CPU1-Upper_ Code #

The main CPU (aka. _CPU1 Discovery_) firmware is splitted in two parts:
- The proper _CPU1 Discovery_ firmware, with the main code.
- The _protected upper memory_ firmware, which is programmed during _OSTC4_ production, and contains (amongst other things) code used to upload and install firmware upgrades.

## Make a specific project ##

Follow the same procedure than for [CPU1-Discovery](Detailed CPU1-Discovery Project.md), (same processor, same includes) but include the `CPU1-Upper` source directory.
