System Workbench for STM32

Hi Mark,
Thank you for our email. I have already tried this procedure several time but it does not work, couple of points.

a. There are 4 projects (sample code) in this package Only one project (PingPong) uses the USE_BAND flag.
The other 3 projects use REGION_XXXX such as REGION_EU868 switch. Its described in region.h file.

b. I changed the pre-processor flag as follows:
project> Properties > C/C++ Build > Setting > Preprocessor
it had following setting:
STM32L072xx
USE_B_L072Z_LRWAN1
REGION_EU868

I changed REGION_EU868 > REGION_US915 but it does not change the frequency sounds like it hardwired to the EU868 switch, I tried finding the define statement in the code but was unenable to do so.

will appreciate any help,, Thx
