Thanks! I was hoping you would suggest ESB! I didn't want to waste effort trying it only to find out it wasn't supported. I'll start hammering together the project with ESB then as the chosen champion for communication.

Assuming your data rate is low since you've selected Lora. Using Bluetooth with Coded Phy would give that range.

Hi Peter,

Yes, Mesh and ESB could be the choices. Mesh allows devices to relay messages, creating a robust network that extends coverage through multiple hops. It is designed with power efficiency in mind, which is crucial for battery-operated sensors. But setting up and managing a Bluetooth Mesh network can be more complex compared to simpler point-to-point or star configurations. ESB provides low-latency communication, which is beneficial for real-time sensor data collection and is relatively simple to implement and manage. It is also designed to be power-efficient.

Please take a look at this ticket.

There is also the ESB guide which might be of help.
