Any one knows for support for heltec_wifi_lora_32_V3?

While browsing and reading the source code of the Heltec_ESP32 library, I found LORAWAN_PREAMBLE_LENGTH=8 as the default setting and have now removed it from platform.ini.
You now have the option of generating the devEUI randomly or from the chipId. In addition, for appEUI and devEUI, bits 0 and 1 of byte 0 are set according to the post: DevEUI for non-hardware assigned values - #23 by terrillmoore.
I will work on entering the EUIs and the key via the serial interface over the weekend.
