I have bought ESP8266 ESP-01 module, the black one, with 1MB flash, with "AI - cloud inside" text on board.
I tried with AT commands on Putty with all possible baud rates with no luck. Then I set the baud rate to 74880 and reset the device, which gave me something like "main_ets.c" as response. I googled a little and read somewhere that module is blank.
First, I downloaded the latest version of SDK "ESP8266_NONOS_SDK_V2.0.0_16_07_19" and flasher and successfully flashed the module. Again tried some AT commands with Putty and it worked. AT commands work, but WIFI is not working. AT+CWLAP not listing APs, just returns OK (I tried with two different APs). I tried with station and AP+station mode, nothing. When I set it to AP mode, I do not see its wifi network from my phone and notebook.
I have downloaded other versions of SDK and flashers and some AI thinker bins. Flashed successfully. AT commands work, but no APs listed, no WIFI, nothing.
Is it possible that only wifi part of the module is not working? Somobody with an idea?
P.S. I tried with two different power supplies and with both of them the voltage drops from 3.3v to 2,8v when I connect the module.
