Finding conflicting info when trying to research this on my own I think because of the different products and how the methods have evolved over time - but if we have an msom device and our desire is to get location info say once every 10-30 minutes - and this location would include wifi/cell tower approximation if the gps couldn’t get a signal - what is the preferred way to do this today?
Do we have to manually code something on the firmware to generate and then publish this data to a service we need to then collect? Or since the particle cloud is already getting this info apparently by default can we just query that whenever we want?
The M-SoM does cellular tower geolocation from device vitals once per week if enabled. See location. On enterprise plans, you can do it more often. This does not incorporate other features like GNSS or Wi-Fi geolocation.
Using Wi-Fi geolocation requires location fusion. This is included on all Tracker devices. For M-SoM (and other non-Tracker devices), it typically requires an enterprise plan, as the basic and plus plans do not include location fusion. It can be used on the free plan, however each location fusion query counts at 50 data operations, so you may reach the monthly limit.
On the M-SoM, if you are using the built-in GNSS (or an external GNSS), you can use that to generate loc events. Optionally you can also fall back to using Wi-Fi or cellular tower with location fusion on plans that allow it. This is not built into Device OS, and you will need to manually generate the loc events as there is no equivalent to Tracker Edge on M-SoM.
