Try different baud rate, try 9600 or 115200 and see if it fix your issue

I have been switching between those two to see if anything changes. Its mostly just the speed of random characters.

Random stream of characters could be GPIO2 held low while booting. GPIO0 has to be HIGH (3V3 VCC via resistor) so does CH_EN (and if you want RST via resistors). GPIO2 could be either left floating (it is set to VCC while booting) or you could pull it up via a resistor.

This is an esp-01.
I am using an ftdi232 also to communicate, set to 3.3v.

It seems like ive tried every combination. I have had both gpios, vcc, and ch_en on 3.3v before I plug it in. Do I need to pull one of those after I plug it in?
The only response I get from it is when vcc and ch_en are on 3.3v, thats when I get non stop characters or feedback from the unit.

Should I try using my arduino to communicate?

Which module revision do you use?

ESP-01
