This is great. If of interest, please consider adding Hubble Networks's scanning gateway SDK to your devices in the future (https://hubble.com). Happy to chat privately about what incentives there may be available especially at logistics warehouses.
You're right, and Hubble Network (https://hubble.com) is proof. We make commodity Bluetooth LE chips talk to satellites. That required antenna design and link budget work no software abstraction would fix.
Hubble does the deep RF work so that firmware engineers building IoT devices never have to.
Hubble Network (https://hubble.com) is building something similar - an open, global BLE network.
Both let you transmit arbitrary data, but the custom setup here is a lot of overhead. Hubble gives you an SDK and lets you get back to building your device.
