I can only see REG_INTERRUPT_SOURCE_B here. What about REG_INTERRUPT_SOURCE_A ? Is it automatically read or is there something missing here ?

Anyone got interrupts to work?

I am using the following code : sx.begin(address); uint16_t intStatus = sx.interruptSource(); // Read and clear int status Serial.println("intstatus:"+String(intStatus, BIN));

Ofcourse I have also followed the other example and added the requisite lines for enabling interrupt, but somehow I am getting intStatus = 0 everytime.

It reads values from register A also. Closing this issue for now.
