#18794 How are you connected? Is it possible that your wires are too long, improperly grounded, catches too much noise, weak power supply and thing like that?
If you can provide a schematic of connection or/and make a picture, that may give more ideas.

So maybe this whole thing is just not enough power.

It could be a power problem. Sending data is when the esp uses the most current.
But I've been using the 3.3v on an UNO w/o a problem.
i have a test sketch that sends different length strings of random chars. The recving end is a perl script.
I use it to test different modules to make sure they work consistently.
If you're interested I'll attach the code and script.
