Before project configuration and build, be sure to set the correct chip target using:
```bash
idf.py set-target <chip_name>
```
To configure the project, you can follow these steps:
1. In order to maximize throughput, we need to set the uart print baud rate at `921600` or more:
Go to: `idf.py menuconfig --> Component config --> ESP32-specific --> UART console baud rate` and set to `921600` or `1500000` and don't print too much log.
2. We can only test notify or write throughput at the same time, this demo default to test the notify throughput, if want to test the write throughput,
4. Should change the CPU frequency to 160 MHZ or 240 MHz in the `idf.py menuconfig` and `Component config ---> ESP32-specific ---> CPU frequency (240 MHz or 160 MHz)`.
5. Should change the bluetooth controller and Bluedroid run in different Core in the `idf.py menuconfig` on `Component config ---> Bluetooth ---> The cpu core which bluetooth controller run (Core 0 (PRO CPU))` and `Bluedroid Enable ---> The cpu core which Bluedroid run (Core 1 (APP CPU))`.
6. In order to maximize throughput, please test in a clean environment without many BLE devices working and esure both test devices are ESP32.
