ESP8266 Community Forum

- Sun Dec 27, 2015 10:15 am #37231 I am new to esp8266 so forgive if this question seems basic .
I got one 2 weeks ago and played around with it by connecting it to an Arduino uno and using Arduino serial monitor.It worked fine and responded to all AT commands
However,once I was using AT+CIPSTART command and it was not responding and being the impatient guy I used AT+RST command .Thereafter a load of garbage came on the serial monitor which didn't stop unless I unplugged it from the computer.
Later I flashed it with firmware .However now it doesn't respond to AT+CIPSTART and some other commands
I used this firmware flasher

What is the problem and solutions
Also if it's a problem of the firmware ,can I get a link that works along with instructions on how to flash .I searched a lot but seem unable to find a suitable one.

- Sun Dec 27, 2015 12:57 pm #37249 When you press reset button or re-power what does your serial terminal say......
1> nothing --- change terminal baud and reset again usually 9600 or 115200....
2> you will see meaningfull info when baud is correct......
If AI thinker then probably supports AT commands
If Nodemcu then supports LUA commands
yada-yada-yada
3> Try using ESPlorer v0.2 for the serial monitor .. very usfull & works well

4> for flashing try ESP FLASH TOOL V2.4

Firmware - google to find etc
Nodemcu - use Frightantic.com [dev/sdk1.4.0] build 7 preselected + desired modules
Basic -- ESPBasic.com -- code + flasher
AT+ can get sdk 1.5.0 from Espressif -- Might be difficult for 1st loads [multi-segment]
ArduinoIDE, + others available

sorry for jumping in this post but I prefer this way instead of open a new thread.
I have a very similar problem. I have an ESP-01 that works perfectly, and a new ESP-07 that i'm not able to make it work.
I'm using Arduino UNO as serial communicator, ESPtool as flasher, and CoolTerm as interface.
When I connect ESP-01, I can have various answers vía CoolTerm to AT Commands, and also queries vía ESPtool such as flash_id or read_mac works fine.
When I connect ESP-07, I still have answers to queries vía ESPtool, but I'm not able to have any good answer from CoolTerm AT commands. I already flashed successfully to ESP-07 firmwares SP_8266_BIN0.92.bin and v0.9.2.2_AT_Firmware.bin. I'm now trying with 0.9.2.5 version but I'm not expecting something different.
Any idea?

Thanks
