JJS,
Before I contact Meshcore directly, I thought I would run this by you first. I bought 2 Heltec V4 devices per your recommendation and set them up watching the video. I think they’re done correctly. When I get to the flashing part I get an error message that states it didn’t work because it’s “looking for a serial port.” Any suggestions?

This happened to me, and I discovered I had selected the wrong device from the flashing page on their website.
Another time I had an issue was when I accidentally chose ‘Companion USB’ instead of ‘Companion Bluetooth’.
Be sure to select Companion Bluetooth when you flash it. Or just re-flash it if you’re not absolutely certain you selected Bluetooth.
Let us know how it turns out.
