Hi, I found an old uart example (for Bluetooth SDK 2.4.x) and tried to migrate it into the latest SDK. Alas, things seem to have changed too vastly (for example, we do not see any hardware configurator file for newly generated projects), so I was not able to run it succesfully. It would be a great help if there is an newer example.
The project in the zip file is using the old SDK.
But you can use the attached .c and .h files in newer SDKs.
Thank you for your advice. After a little work (I had to forge uart_echo.h which is missing &c.) now my BGM121 on SLWSTK6101C flawlessly echos input from uart!
