If a person’s ICM, or loop recorder, uses a cellular or wireless signal to connect with the data transmitter, it is unlikely to interact with their Bluetooth® devices. If a person’s ICM uses Bluetooth® to connect to a phone app, it is using a special type of Bluetooth® called Bluetooth® Low Energy, which is not compatible with Bluetooth® Classic (the type of Bluetooth® in most cars). Check with the manufacturer on the way connectivity may impact your device.
