NRF24L01 vs ESP8266: How to Identify Modules and Firmware Upload Issues with ESPlorer

Hello . I recently purchased two modules for Arduino . When I bought them the first one was under the name - "NRF24L01 NRF24L01+ Wireless Module 2.4G Wireless Communication Module Upgrade Module" . When I got it I did some looking at pictures of this module on the internet and it appeared to me that it is an ESP8266 serial WIFI module . So reading the descriptions I tried to upload to it the latest firmware (something like file -AT22SDK100-2015-03-20-boot1.2) Firmware goes into the module without any problem . Then I want to upload to it with ESPlorer the wi-fi network configuration , etc configuration data . And here there is already a problem . The program seems to load , but after each line it gives an eror . It does not help to change the upload speed or other configuration changes . I should also add that when I use ESPlorer to send him ready-made commands sewn into the program buttons (e.g. AT), the module responds OK . Please help in deciphering what module I finally bought . Below is a picture .



While the second module was described as - "ESP8266 serial WIFI model ESP-03"
And I am also no longer sure what it is . Is it just a wireless module , or is it already a wi-fi module with wireless support . If anyone has already had such modules then please direct . Here is a picture of the second module .

And the internet is silent, isn't it? No one in the world knows what the ESP-03 is with the ESP8266....

Both modules are functionally identical, the first being the ESP-01.

If I still knew how to search for something in foreign languages , then maybe something could be found . So I can assume that the module from the first photo is not NRF24L01 and after programming it should connect to my wi-fi network. But why can't it be programmed ? . You can forget about the second module , because I tried to make legs for it , but this baby is so small that I cut the tracks and the module to the trash .
