Both advertise iBeacon, Eddystone UID, Eddystone URL, Eddystone TLM and battery level to a range of up to 100m. They support button triggered (single/double/triple/long click) broadcast for detecting in apps or via Bluetooth gateways.
The B1 differs to the B2 in that the button is labelled ‘SOS’, has a larger CR2450, rather than CR2032, battery and also includes a wall mounting plate.
