Need some help with ESP8266 modules.
Posted: Tue May 19, 2015 11:12 amHello,
I have two ESP8266 modules. Connected each of the modules to a PC via a TTL serial to USB converter and powered the modules with 3.3 VDC.
On the computer I am running a Terminal program set to 115 kbaud.
Below is a copy of what I am getting from either of the modules on power up or on hard reset. As you see, after some gibberish the modules respond with "ready", however my attempts to send some AT commands produce no action and no response other than echo.
I need and will appreciate help figuring out what I am doing wrong or what I am not doing and should be. I do have a jumper between Vcc and CH-PD pins on the header.
The modules here are certainly at 115k, they don't do anything on 9600, but respond with "ready" on 115k. Are they supposed to boot from the on-board FLASH or a UART boot is necessary even if I am not trying to customize the firmware?
Regards and thank you in advance
