Got ESP-05. Made interface circuit that allows to talk to ESP05 via USB from computer.
Getting message as on picture:
The two types on interface used as on pictures below:



To talk to ESP05 using minicom on linux machine. Can see SSID on wireless network. So this gizmo seems to be working .... sort of. Can assign IP of choice, and router address while setting connection to the ESP05 on computer WiFi settings (macMini Apple).
When you look on diagrams the pinout on ESP05 seems to be different than published on the net.
When get from ESP response "ready" - this happens on reset by pulling down RST pin.
Trying to send AT commands .... nothing comes back from the ESP. Using oscilloscope for monitoring ...... and line sits at 3.3V. No signal.
Qustions:
1. AT commands - which way have to be issued? AT RST ( as old days on Hayes modem ) or AT+RST ??? (for example).
2. Is it possible that pin 2 is "dead" ????

Any ideas, please help
Thanks for your time, regards

If you see the "ready" coming in to your PC, that means "RX" is working.
When you type a AT command, do you send "CR/LF" at the end, not only "CR" ?

I try can not remebr exactly right now. Going to try again. There are options in minicom to have auto LF. I thing this is ON.
When ESP is "on the air" would RX line give the "messages" from the air that ESP can hear/see ??
Also was trying other comms programs like putty and xc. But could not see even reset message.
Strange ... from pinout pictures on internet do not correspond to actual pinout, RX and TX seems to be swapped. Is this normal ???
By the way bot interface circuits work fine.

Thanks for your time ...... K

Hurray .... got ESP 05 talking back.
I do not know the reason, fromexperience in electronics World at times washing the board in alcohol (methylated spirit) did the job. So put the module in the metho for a while, shake a bit and tha let it dry.

Copy of the conversation with ESP

ready
AT=RST
no this fun
AT=CIFSR
no this fun

wrong syntax

ERROR
AP+CWMODE=1
wrong syntax

So something happening but commands are wrong ..... looking on the net for answers.
Any idea where to find command list ?
Tried commands people put in the source code for their Arduinos, so far none of them did work. I guess different versions must have different command sets.
Using xc on linux box.

Thanks for your time Kris
