      Hello! I'm trying to create a LoRa Mesh or PyMesh network. I'm using LoPy4 and FiPy with expansion board 3.1v. After a few problems, I was able to create a PyMesh network using Pybytes. I have a project on Pybytes with WiFi and LoRa added as networks.

      The devices have the same firmware version (1.20.2.rc11). They connet to Pybytes and they get a role (the rgbled change its color). However, I checked the monitoring tab and they don't find neighbours.

      Moreover, I set the FiPy as Border Router, but something happened because in the image above it isn't appear as I defined previously.

      I'm running tests right now, the FiPy is the leader of the network (MAGENTA) and the LoPy4 is a router (GREEN). Do I need another LoPy/FiPy to find neighbours between them?

      I read the tutorials in the Pycom website, but I'm getting a bit confused because what I found here (https://docs.pycom.io/pymesh/licence/) works, but couldn't find neighbours in the network, and what I also found on the website (https://docs.pycom.io/firmwareapi/pycom/network/lora/pymesh/) doesn't work. It throws an error:

      The code above had some core dump info but it was a bunch of letters without much sense and I decided not to put it here.

      So I would appreciate if someone can give me some hints about whats happening or what to do now.
