 ## Hardware Setup
 
-This example uses esp32 chip to run the example `bleprph_host_only` that runs the nimble-host and sends and receives the commands and events using uart. The another chip used is esp32c6 that runs the esp-hosted `esp-hosted/esp_hosted_fg/esp/esp_driver/network_adapter` example that runs the controller and receives commands and sends events using UART. Below is the setup of esp32 and esp32c6.

-Note that the esp32s gpio pins tx=4 and rx=5 are defined in [uart_driver.c](../main/uart_driver.c) file. The tx pin of one chip connectes to the rx pin of the other and vice versa.
+Note that the esp32 gpio pins tx=4 and rx=5 are configurable using idf.py menuconfig -> example config -> Uart Configuration. The tx pin of one chip connectes to the rx pin of the other and vice versa.
