The default communication interface is port 0 of ESP32-H2 UART running at 460800 baud, change the configuration in [esp_ot_config.h](main/esp_ot_config.h) if you want to use another interface or need different communication parameters.
### RCP Size Optimization Configuration
To optimize the size of the RCP firmware, the following configurations are enabled by default:
```
CONFIG_COMPILER_OPTIMIZATION_SIZE=y
CONFIG_COMPILER_OPTIMIZATION_ASSERTIONS_SILENT=y
CONFIG_COMPILER_OPTIMIZATION_CHECKS_SILENT=y
CONFIG_COMPILER_SAVE_RESTORE_LIBCALLS=y
CONFIG_ESP_ERR_TO_NAME_LOOKUP=n
CONFIG_ESP_SYSTEM_PANIC_SILENT_REBOOT=y
CONFIG_LOG_DEFAULT_LEVEL_NONE=y
CONFIG_NEWLIB_NANO_FORMAT=y
CONFIG_OPENTHREAD_LOG_LEVEL_DYNAMIC=n
CONFIG_OPENTHREAD_LOG_LEVEL_NONE=y
```
Configure them via `idf.py menuconfig` if you need.
The firmware size are as follows (reference value):
```
Before Optimization After Optimization
esp_ot_rcp.bin for esp32h2 314KB 184KB
esp_ot_rcp.bin for esp32c6 299KB 208kb
```
### Build and Flash
Build the project and flash it to the board:
