That's why it uses AT commands by default - it looks like a modem. The ESP modules are clever, but it all depends on what you want to do. They have limited I/O because they are actually microcontrollers. Linking them to something like a CMM2 opens up a lot of possibilities that they couldn't do otherwise. True certainly that the CMM2 offers many features unavailable on the ESP8266 and ESP32, especially the advanced graphics, but otherwise much of the pin I/O available with MMBasic is also available with Annex on the ESP. Some other uses of the ESP-01 with the CMM2: jirsoft's Napoleon Commander, frnno967's Maxiterm BBS client, html server.
