Hello all,
I'm new to the ESP8266 scene and so far I haven't been able to do much. I've purchased black ESP8266-01 modules (apparently those are 512k+512k boards) and flashed some firmwares, but I don't get the modules to work properly using AT commands. I tried the following:
- NONOS_SDK 1.5 following this tutorial: http://www.allaboutcircuits.com/project ... fi-module/
- AT firmware 1.3 using this tutorial: http://www.electrodragon.com/w/ESP8266_AT_Commands
Both times, the firmwares seem to flash just fine, but when I reboot the ESP board, I cannot communicate through Putty. This happens:
- NONOS SDK: The red led is very dim and I can only receive communication when I use a baud rate of 74880. This is the error I'm getting
ets Jan 8 2013,rst cause:2, boot mode:(3,6)

2nd boot version : 1.5
SPI Speed : 40MHz
SPI Mode : QIO
SPI Flash Size & Map: 8Mbit(512KB+512KB)
jump to run user1 @ 1000
- AT 1.3: everytime I press the reset button, I get this message: "don't use rtc mem data". I cannot send AT commands.
FYI:
when I sync the ESP flash donwload tool, I see this information:
flash vendor:
E0h : N/A
flash devID:
4014h
QUAD;8Mbit
crystal:
26 Mhz
What am I doing wrong? i'd love to get started with this very interesting device, but this is holding me back. I've searching for some days now for a solution, but I didn't find any... Any help is greatly appreciated!
