Simple AT command using ESP32-WROOM and usb/ttl connector

Postby momen_ahmed » Fri Sep 13, 2024 1:24 pm

I'm trying to test the AT commands with esp32-WROOM and usb/ttl ,
the connections : Tx of esp32 -> Rx of ttl
Rx of esp32 -> Tx of ttl
3.3v of esp32 -> 3.3v of ttl
GND of esp32 -> GND of ttl
EN pin of esp32 -> 3.3v
GPIO0 of esp32 -> 3.3v (for normal mode)
after that when I test a simple AT command that's what appears
