I was trying to connect LoRa SX1278 module with ESP 32. I have done the wiring exactly as sown in the tutorial. but while running LoRa Sender code on ESP 32 I got the message
”

rst:0x1 (POWERON_RESET),boot:0x3 (DOWNLOAD_BOOT(UART0/UART1/SDIO_REI_REO_V2))
waiting for download”
or when i connect IO0 to 3.3 V and run again I get
“rst:0x1 (POWERON_RESET),boot:0x1b (SPI_FAST_FLASH_BOOT)

Hi.
That means your board is constantly in bootloader mode.
If GPIO0 is being held low or floating at the wrong level, it will cause you to stay in bootloader mode.
You need to make sure that IO00 stays high when your toggle the enable pin to reset.
