esp-at v1.2 with SparkFun ESP32 Thing

[almoniplo]

Hi,

I want to flash esp32-at project to my SparkFun ESP32 Thing board.

I matched the uart settings to my board - UART0, RX (GPIO1), TX (GPIO3), RTS (GPIO22), CTS (GPIO19), and flashed version 1.2 successfully, but didn't get READY in my terminal (I use HyperTerminal).

In addition, I downloaded ESP32 AT Bin V1.1.3 and Espressif's official Flash Download Tools and tried to work with that, but got gibberish in my terminal (already checked the baudrate).

Did anyone flash esp32-at project to SparkFun ESP32 board before? What did I do wrong?

Thanks a lot!

AT command is via GPIO16, GPIO17 by default. Could it due to the wrong pins?
