Flashing pre-built esp32 binary

Hooray!! I found the problem. Your package uses the 80MHz SPI speed. Flashing with the 40MHz and using corresponding bootloader yielded success! So what I did was: esptool --chip esp32 --port /dev/ttyUSB0 --baud 115200 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_freq **40m** --flash_size detect 0xe000 **boot_app0.bin** 0x1000 **bootloader/bootloader_dio_40m.bin** 0x10000 ESP32_OpenMQTTGateway_V092_BLE.bin 0x8000 ESP32_OpenMQTTGateway_V092_BLE_partitions.b…
