ESP8266 Community Forum

- Sun Dec 27, 2015 11:43 am #37241 I just posted in guru for some help.
Still waiting for other esp8266 demo boards to arrive with AT commands recognition?
I still remember trying to use Zilog's new development tools and got lost in all the includes/not includes during assembly.
Listing got too confusing to follow in the emulators.
I do better doing one small thing/step at a time.
Understanding it inside and out then adding one module at a time.
Thanks again,
Ray

I still having problems with any serial communication for re-flashing using my pc and serial link.
I do have other boards coming.

(sorry if my post is duplicated... )

did you manage to get it working?
i can receive the AP info on startup on any terminal (putty, etc) with 115200 bps, but i can't send any AT command toward this 'yellow board' ESP 12

i can connect to it via wifi with the app Android and with my notebook also.

but i suppose no AT commands means no chance to flash it ...
still trying...

if you succeeded please tell me HOW! thank you!!!

AT firmware has nothing to do about the Flash upload procedure, the latest is handled by bootloader placed in ROM.
You can upload any kind of firmware to replace the AT firmware.
