double display using wireless connection ,, wired is ok

By xtal
- Mon Sep 07, 2015 7:44 am #28425 using the following code with a wired connection to AP and wireless to ESP , the ESP displays single page,, then pressing blink button , the picture and data values can change....Using a wireless connection to AP and wireless to ESP, then pressing the blink button , it is appending to the display rather than over writing i.e. looks like double display...
