multiple definitions of 'operator|='

Re: bluetooth code size enormous

i tried to compile esp-idf example to verify the size .... and its 715kb (compared to 950kb with arduino) ... still quite huge for something that doesn't do much (if you want to use OTA with it ... you have like 300kb left for your other code (and other libs ... like wifi and stuff) ... but running ...
