Today, I finished 3D-printing the last two cases for my setup of three handheld LoRa RNodes.
The nodes are based on Heltec v4 boards and work great as far as I tested them.

I'm hyped about using them for off-grid secure and private communication in the future.

It is incredibly easy to clone, modify and build the official RNode firmware.
After realizing this, I went ahead and customized each RNode's bluetooth device name by changing the firmware source.
For this change, only Bluetooth.h and Display.h needed to be touched.

I encourage you to get into RNodes aswell and throw down the shackles of IP-based communication.

Internet?
Where we're going, we don't need Internet!
