Heltec LoRa 32 V3

[scapingerman]

I’m attempting to implement RF95modem with a Heltec LoRa 32 v3, which uses an ESP32-S3 microcontroller instead of the standard ESP32 in previous versions. To match the pin layout of this Heltec v3 model, I’ve configured the following in platformio.ini:

[env:esp32s3_heltec_config]
platform = espressif32
board = heltec_wifi_lora_32_V3
framework = arduino
build_flags =
-fexceptions
-DRFM95_CS=8
-DRFM95_RST=12
-DRFM95_INT=14
-DUSE_DISPLAY
-DOLED_ADDRESS=0x3C
-DOLED_SDA=17
-DOLED_SCL=18
-DOLED_RST=21
lib_deps =
${env.lib_deps}
${env.libs_display}
board_build.partitions = no_ota.csv

When running pio run -t upload -e esp32s3_heltec_config, it compiles successfully, but when opening the Serial Monitor in Arduino IDE to check the initialization message, I get the following LoRa radio initialization error:

Any guidance on resolving the LoRa radio initialization issues would be greatly appreciated.
