need to connect two esp module using SPI or UART.

[valmik thakar]

hi,

i use ESP-WROOM-02 module for our project.
as per our requirement we need to connect two esp modules with one esp module using UART or SPI.

one device can connect with UART because uart0 have both rxd/txd pins but uart1 have only txd so we need to use spi for another module. i port spi.c lib got from https://github.com/MetalPhreak/ESP8266_SPI_Driver.
but can anyone suggest me ,how can i communicate with two esp modules using SPI.
how can i make one esp as a master and another esp as a slave ,so i can communicate over SPI.

or if any one have a idea of how can we connect two esp using UART please answer me about that.
