This is still a problem for me in 2.6 and 2.7 but not in 2.5. Is there work going on to fix this or a way to go around it?

OK I noticed the comment of not supported random(). But if this break on every windows it is maybe better to have the switch in the opposite way or default...

Take a look at https://github.com/thomasfla/Linux-ESPNOW But you need a wifi adapter with monitor capabilities so the RPi wifi adapter will not do.

Download autmake 1.14 from [here](http://ftp.gnu.org/gnu/automake/) and put the install folder in you path and continue the build might help.

I second this. The IV should preferably be generated new on each send and be sent along the frame.

@lhespress What do you mean with interaction? Is't it as easy as adding a 16-byte random IV (in clear text) at the end of the payload which was used together...

@lhespress Works perfect here. Thanks a lot for this one a truly fast patch indeed. Impressed!

@chenlijun99 no but it prevent the key from being exposed in a much better way then to use a static IV. I guess one must have some sort of time...

@chenlijun99 It's always also a matter to say how far you should go. esp-now is very nice in it's simplicity and used for not critical tasks I guess it is...
