How to build DTM for BlueNRG-1 from sources?

Hi,

I cannot build working DTM for BlueNRG-1 on TrueSTUDIO (9.0.0).

When I program the device with prebuilt DTM_SPI.hex from Firmware folder in ST Development Kit it works fine. STM32 connects with BlueNRG, configures it, etc.

Unfortunatelly, the program built from sources (Projects/BLE_Examples/BlueNRG-1/DTM) is not working. It looks like BlueNRG does not raise IRQ line for notification its initial event.

Below I illustrate comparison of initial sequence for these two programs.

What I am missing in compilation?

Regards,

Piotr

PS

I am using idb007v1 board.#truestudio #bluenrg-1 #dtm #building-from-sources #st-development-kit

My misktake.

I followed reference design STEVAL-IDB007V1 where BlueNRG has two CS lines:1) one for control a sensor,2) second for communication with host processor.

I controlled incorect one.

After fixing this, everything works fine.

Comparing to IDB007V1 I noticed only one minor difference: my BlueNRG-2 starts little slower - maybe a consequence of higher frequency of a clock 32MHz vs. 16MHz.
