Hi @freynder , and thanks for your help.
I use Arduino IDE with stm32duino library to compile and upload . I haven't change the bootloader.
This setup works without problem on my bluepill ( I had run several example without porblem, specialy to found which uart pin are used by stm32duino).
I had a STLink connected to my blue pin (JTAG Clk/Data and SWO (and GND of course)).
I have enable debug option : #define MY_DEBUG and #define MY_DEBUG_VERBOSE_RF24
Here is the output of my compilation/upload :
