Thanks for your swift reply.
I seem to have sorted the problem as I now have the naturewatch camera working as it ‘says on the tin’
The problem seems to lie with my Android device running Android 4.4.2 (Kitkat).
I too was getting the ‘double’ try to connect the wifi. The first time it rejected the badgersandfoxex password and presented the password box again. The second time I entered the password it logged me in but then presented the issues I described in my earlier message.
Whilst waiting for your reply I suddenly thought to try my laptop running Win10 and ‘hey presto’ it worked first time!
So it could be that the wifi on the Samsung Galaxy Tab3 (or Andriod 4.4.2) doesn’t implement the wifi in a way that Raspberry Pi Zero likes?
So your suggestion of ‘Try another device’ was indeed inspired.
