By the way, you can use the green light from HRM sensor as a flashlight in bjs2.
Just run HRM and shine it in a dark place, visibility will be much higher than from the screen as a flashlight ⚡

Thanks for the tip! 🙂

Was also thinking it could be used for some sort of communication when BLE does not work or is too complicated similar to IrDA or NFC - sending via blinking (led or even display) and receiving by the sensor. Display to HR sensor is unidirectional but two sensors pointing each other could be bidirectional.

Maybe a flashlight on model 3? Could be neat!
