The ESP8266 shuts down internal clocks to save power. Please use a GPIO trigger to wake the chip up from light sleep before resuming with operations. Try AT+WAKEUPGPIO command before sleep mode.
Also, take a look at the attached guide to understand sleep modes better.

[SOLVED] Strange behavior after AT+SLEEP=1

2016-11-04T19:27:27+08:00

Hi,

I am using Huzzah as development platform. I installed AT command firmware from SDK 2.0.0.

My command set is simple:

AT+CWMODE_CUR=1
AT+CWJAP_CUR="bitoad","ropuchabi2"
AT+SLEEP=1

I have found that after AT+SLEEP=1 ESP is less responsible then without it.
I need to try AT\r\n several time to trigger OK. ESP ignores that commands and react after 2-6 retries.

I am testing on FTDI with Rx/Tx/VCC/GND connected on Putty and terminal emulator on Mac.

Is it normal behavior? Why?

Thank you in advance for help.

Best regards
