Why is my custom board SX1280 not changing the values of the IRQ flag? It is always 0. One more problem is when I receive with this code, the value of buffer[0] is equivalent to the received packet length is always 0. Please help me to solve the problem this topic, thank you very much.

Hi !
Make sure you set irqmask and at least one DIO with the bits you want to check with your read command. Else, the chip is not toggling them.
