I'm trying to run an example program - BLE_Sensor DEMO - built from sources.
I am using TrueSTUDIO for STM32 (v.9.0.0). The sources are from BlueNRG-1.2_DK_2.6.0 kit.
Unfortunatelly, when I download the image, the board does nothing: no led blinking, no BLE communication.
However, when I download prebuilt image (from Firmware folder in the development kit) it works fine.
What I am doing wrong?
