# Troubleshooting communication with ESP-12e

I have an ESP-12e and set it up like here with the exception that I am using FT232RL chip. The problem is I can't receive anything from the module despite the command I send. When I try to connect the REST pin to ground for a second I get garbage on putty.

What I tried:

1. Different baud rates.
2. Connecting REST pin to ground for a second.
3. Used CR after LF and vice-versa in Putty.
4. Used ESPlorer software.
5. Powering it from a standalone 3.3V line from an ATX power supply instead of using a 3.3 voltage regulator.

If I'm not mistaken I have seen that some are using capacitors with the 3.3V line going to the module (Which I am not using). Anything we can do before concluding the chip is broken? Because I haven't run it in a like a year.

• The default baud rate for esp devices is 74480 if I'm not mistaken .. or 74840 ... it's a very strange baud rate ... are you using it with AT+ commands or are you programming it? I think the AT+ commands source is 115200 baud – morcillo Apr 4 '18 at 16:37
• Well I found out I am connecting in firmware mode through GPIO pin to ground. I disconnected it and now I can see it but through termite not putty. – 3bdalla Apr 4 '18 at 16:39
• Try programming it ... download esptool or the espressif flash download tool and program it before declaring it gone .. also you may have inverted the tx and rx pins (seems to be very simple and sometimes you assume you know the pins and just connect them .. I know I've done that many times) – morcillo Apr 4 '18 at 16:40
• Then maybe try clearing CR and LF ... try using putty in the simples way possible, it has to work – morcillo Apr 4 '18 at 16:40
• I will look into your suggestions. Thank you very much! :) What do you mean by clearing CR and LF? – 3bdalla Apr 4 '18 at 16:41
