I had a working encrypted mesh based on a self-compiled 18.06.8 openwrt solution. I also used wpad-mesh-wolfssl for the encryption of option ieee80211s_encryption 'psk2+tkip+ccmp' as described in the lime-community-example. This worked very well. Now I upgraded with the same options to 19.07.3. There I only got SAE-AUTH Failures. (No connection between the nodes) After some research I changed the encryption to wpad-mesh-openssl. Now it is working - but the package is much bigger than the wolfssl. Shouldn't this problem be mentioned somewhere in the Instructions? Is there another solution with wolfssl? Thanks, Andy
