Strange behaviour - Check Wires and Version Mismatch
-
Hey @marceltrapman - I just upgraded one of my sketches from 1.3 to 1.4 ( im finally moving to 1.4 in "production!!)
Anyway, i had the same issue with version mismatch error and spewing out
version mismatch read: 255-255-255 s=255,c=7,t=255,pt=7,l=31:NAN version mismatch read: 255-255-255 s=255,c=7,t=255,pt=7,l=31:NAN version mismatch read: 255-255-255 s=255,c=7,t=255,pt=7,l=31:NAN version mismatch read: 255-255-255 s=255,c=7,t=255,pt=7,l=31:NANwondering wtf was going on, i disconnected the relays board connected to VCC... the messages stopped and everything worked correctly- other than the relays actuating...
figured it could be a power issue, i connected proper power source as the issue occured with just a USB 5v from my PC....and reconnecting relay all worked properly..including now the relay.So, check your powersupply!
HTH..

I don't see the version mismatch thing anymore luckily but it would have surprised me if it was power. Not only did I check it but I also use a power converter in this case to supply constant 3.3v (I use pro mini 3.3v).
Anyway, thanks for the tip :)

Same here. I had to go up to 5V to power my Arduino Pro Mini 3.3V sufficiently.
