Is it possible on Wear OS to constantly record heart rate data and/or other sensor data in the background and send it via WiFi/4G without a phone?
Can such a service start on boot?
Can I run a service in the background on Wear OS, constantly sending heart rate data via WiFi/LTE?

Yes - but if long lived you must use passive updates to get batched data, otherwise you will likely ruin battery life.

You can request an LTE or Wifi network to sned data when you have enough to send. But you shouldn't try to keep the network open permanently.
