Why get a bus id?
If you are using PJON on a shared medium, like radio, you could end up with device id collisions with buses in close range. Your neighbour could choose the same device id you selected to identify one of your devices, and one of them could have a foreign device in its reception range, exchanging unwanted and potentially misleading data. To avoid this we suggest you to use a valid unique bus id released by the PJON Foundation. Once obtained a unique bus id you will be able to both isolate your device's communication and network with other buses in range.
