I recently bought a couple of ESP modules from Sparkfun and have not been able to get either one to communicate. Here is what I have tried so far.

Direct connection to a Raspberry Pi.
Connection to my PC using a 3V FTDI cable and a bench power supply.

I don't get any messages when I power it up, and when I send a command the blue LED blinks.

Here is how I specifically have things connected.

VCC to 3.3V from a bench top power supply
GND to GND on a breadboard
TX to FTDI TX (Note, I tried it the other way and got no indications)
RX to FTDI RX (see note above)
FTDI GND to GND on the breadboard
The ESP Enable pin to 3.3V

Software that I'm using is CuteCom on a Linux Debian desktop system. I have tried both as a regular user and as root. The settings are as follows.

Device = /dev/ttyUSB0
Baud Rate = 115200 (Note, I did try several other baud rates with the same results)
Data Bits = 8
Stop Bits = 1
Parity = none
Line Ending = /cr/lf

As I said above, the blue LED blinks when I try to send a command, but I get no response. Any ideas? If you need any other information please let me know. Thanks in advance.

the bootloader's default baud rate is 74880 - did you try that?

I tried 74880 as well, still no response.

I went back to attempting communication with a Raspberry Pi and connected it as follows.

TX on ESP to TX on Pi
RX on ESP to RX on Pi
Reset on ESP to GND
CH_PD on ESP to 3.3V
ESP GND to Raspberry Pi GND and external power supply GND

No matter which terminal program I use, I still get the same result. The blue LED flashes when I try to send a command, but no response on the terminal.
