ESP8266 Sparkfun wifi hat with Uno or Mega 2560


i'm using esp8266 wifi project, running sparkfun esp8266 arduino wifi hat , example code sparkfun library. i've been successful running arduino uno, , being able access putty, on ubuntu laptop.

however, when try run same code on arduino mega 2560, thing tells me it's looping forever when accessing putty. run uno, runs fine, run mega 2560, loop forever.

maybe there rx/tx pin difference , need rewiring, maybe need use serial1 command, few other possibilities nothing see on web states issues clearly.

any thoughts on might going wrong?

incidentally, i'm trying mega because had issue uno. using uno/esp8266 web server, when amount of lines of html code using in uno code got past point, 25 lines, server start dropping lines when accessed client (browser on separate laptop). instance, ok, if added 1 button html code, when added second button, not appear. if right clicked on browser @ html source code server, line missing defined second button. 1 curious thing was not line end of code missing, more typically line middle of code.

i hoping error due limited memory resources in uno, trying mega.

please let me know if can me either problem.

thanks,

steve
