Are you using any other library that possibly accessing the same interrupt vector? What version of the Arduino AVR board support are you using?

Hi I am using this with MySensor Library which might be using Interrupts. any possible solution to resolve this issue.?

Hi everyone,

I get the exact compilation error when trying to use it with MySensors 2.3.2 for Arduino Pro Mini. Is there any workaround possible? Thanks very much for your efforts, Joost

Hi all,

I want to use this library with the radiohead encrypted rf95 server and I am running in the same problem. Is there any possible workaround?

Yes I just came across this same thing. I can enable RadioHead RH_ENABLE_ENCRYPTION_MODULE, or I can use Low-Power, I cannot use both else it conflicts.

Go to LowPower.cpp, find this lines

ISR (WDT_vect)
{
    // WDIE & WDIF is cleared in hardware upon entering this ISR
    wdt_disable();
}

and comment it

I know this thread is 4 years stale, but thank you, eldiamond2; your solution helped me!!
