Was asked to post here if BLE solution is legal and deployable.

Hi guys, After getting bounced around by Apple support, I was told to post here to get confirmation(?) about usage of a product we are interested in using. I'm hoping to get some insight on this.

In a nutshell, we found some home brewed software that will allow us to flash an airtag like device with custom firmware. This device can then leverage Apple's BLE and send information(GPS) through icloud to a mac that we purchased(server resides there, we do not run/need Find My). We can then use that data internally to assist first responders. As this would be an internal project, there is no selling, no money changing hands for profit, etc.

Any thoughts if this is something we can do legally? I don't want to deploy this and find out we shouldn't be doing this. To be honest, if push came to shove, and the pricing was reasonable, we would be open to paying Apple a fee if that was a factor.

Any thoughts?
