I’m researching best way to setup painless mesh network. Am wanting to use multiple Fire Tablets outdoors to communicate to multiple esp32 nodes with gps and weather sensors. Would be communicating to a node (mounted behind tablet) so am considering connecting via usb serial rather than wifi or bluetooth to save energy. Reasoning that tablet wifi should be left open in case wanted to stream data to cloud via tablet. Also thinking this might be easier than setting one of nodes as an AP in case several nodes are set to AP. This way multiple tablets on mesh network could be connected to cloud without issues – guessing.
Also wanting to tie data into a custom dashboard built using FlutterFlow. Has anyone used Flutter or FlutterFlow to communicate with ESP32 devices?
I don’t have a clear answer for you. You’ll have to test different methods and see which one works best for your project. With painlessmesh all nodes can talk to all nodes on the network, so it seems a good option.
You can take a look at all the examples and check some of the examples: https://gitlab.com/painlessMesh/painlessMesh/-/tree/develop/examples
I never experimented with FlutterFlow, but now that you mentioned it, it seems a good topic to explore.
