Using an interrupt and LoRaWAN

I know what my problem is now.
i start the interrupt() and hold it for one second this is how i am determining how many pulse per second there are.
then i use noInterrupts()....well this just shut off all my interrupts even the ones sending out bytes to the serial hardware....

Is there a way to just stop the interrupt on Pin 2 and allow other auto background interrupts to still do their thing?

interrupts();           // starts interupt
delay(1000);          //waits 1 sec
noInterrupts();           // ends interupt
