i am developing my project in a stm32f103c8 (bluepill) with Keil and CubeMX, i want to use a nrf24l01 transmitter and for this i looked for a tutorial which is exactly what i want to do. the problem is that when i do it i notice that the radio transceiver does not transmit or receive, i have seen on the internet that some people have problems with this card that i am using, just me this is failing me using this library. I leave a link to a video that shows the same steps that I made in addition to the library. precisely the function nrf24_write is the one that is not working. I hope you can help me because I've been trying to understand why it does not work for several days.
