- ESP32-C3 (single-core) with 4MB flash memory, ceramic antenna, USB port is USB not UART
A workaround is to add or enable in configuration.h:
#define ESP32_WIFI_TX_POWER WIFI_POWER_15dBm
You may also need to lower the value if not working, the possible values are WIFI_POWER_5dBm, WIFI_POWER_8_5dBm, WIFI_POWER_15dBm
