Right way to remember the Wi-Fi credentials in ESP8266

[marcuka68]

Hello, I'm working with ESP8266 for one project in the company. I have a problem to remember the Wi-Fi credentials after successful smart config. The ESP8266 software version is as follow:
AT+GMR
AT version:1.2.0.0(Jul 1 2016 20:04:45)
SDK version:1.5.4.1(39cb9a32)
Ai-Thinker Technology Co. Ltd.
Dec 2 2016 14:21:16
OK

If Use the AT command AT+CWSMARTSTART=1 and after perform power cycle, the Wi-Fi credentials are remembered. I saw that command from older company project. It is not mentioned in the actual AT user manual.

If Use the AT command AT+CWSTARTSMART=1 and after perform power cycle, the Wi-Fi credentials are not remembered. That is the right AT command in the actual user manual. Also try to store the data with AT+CWJAP_DEF, but again no success.

What shall I do to remember the Wi-Fi credentials? Which is the correct way to do that?
