Till now I was very much satisfied with Banggood. I ordered several devices all came very fast, good quality and worked as expected. However, recently I bought ESP8266-03 and ESP8266-07, however, no luck with both. ESP8266-03 is responding to few AT commands (AT, AT RST, AT GMR, AT CWLAP etc) but gives error for AT CWJAP=\"SSID\",\"Pass\". ESP8266-07 even does not response to any AT commands. Any help from Bangggod or anybody els would be appreciated.

  • Zainul Aabdin I used "3.3V 5V TTL Bi-directional Logic Level Converter For Arduino" and it seems this was creating problem. When I removed logic level converter and used potential divider, at least ESP8266-03 module is working now.
