Heltec WiFi_LoRa_32_V3 Compile Error - undefined reference to `Radio'

PlatformIO IDE

Thanks for the suggestion.
Actually, adding -D WIFI_LoRa_32_V3 in the build_flags generates many warning starting with

warning: "WIFI_LoRa_32_V3" redefined

and when linking several errors starting with this one

toolchain-xtensa-esp32s3/bin/../lib/gcc/xtensa-esp32s3-elf/8.4.0/../../../../xtensa-esp32s3-elf/bin/ld: .pio/build/heltec_wifi_lora_32_V3/libaf0/libLoraWan102.a(radio.c.o):(.literal.RadioInit+0x20): undefined reference to `TimerInit'
