Lora expLoRaBLE upload problems

I am running low on ideas.

  1. Back to basics: double-check/reinstall the drivers, the setup of the power supply, and the correct board etc. etc. This issue is caused by something fundamental/basic.

  2. There is another post that is working on the LORA EXPLORABLE with other problems, but maybe that person is better help than me https://forum.sparkfun.com/viewtopic.php?f=99&t=59421

  3. Try to install the Sparkfun bootloader. you can get that from https://github.com/sparkfun/Apollo3_Uploader_SVL

  4. Maybe you have bad luck and 2 boards and should return them.
