WROOM-S2 - SPI AT Commands?

Postby lloureiro » Fri Dec 09, 2016 6:18 am

Hello,

i heard about WROOM-S2 accepts AT commands through SPI(SDIO). This is true?

Im using PIC microchip and need interfacing with SPI and send AT commands over this interface.

WROOM-S2 chip is ready for accept it? Or needs to be flashed?

Thanks a lot.

Best regards.

Hi ESP_Xutao,

It's ready? Or i have to send boot bin file? "-ESP-WROOM-S2 will start only after it receives the boot file sent from MCU"

What kind of device is this??
