Well, definitely 2 good reasons..
OK I will flash them with the latest firmware,
and the single module that has 8Mbit will stay with v1.6.2.
BTW, is it possible to set in PuTTy what type of [Enter] (New Line) to send?
In Arduino IDE's SerialMonitor, we have a ComboBox on the bottom of the window, enabling to select for example "Both NL & CR",
I was looking for something similar in PuTTy,
and only found this:
But according to PuTTy's help, this talks about what to do (to add) to CR/LF coming from the server,
not about what to send to the server when you press [Enter]..
Any idea regarding it?
