Likely a misinterpretation of the error.  I'm guessing either one 
needs to be root to write to this [likely virtual] file, or a 
member of an associated group.  It would help to have the output of

bash$ whoami
bash$ id

and

bash$ ls -lsF 
/sys/kernel/debug/ieee80211/phy*/iwlagn/data/continuous_tx


I'd be particularly interested in the group association and the 
permission bits.
