  • By the way, you can use the green light from HRM sensor as a flashlight in bjs2

    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.

  • hi,
    if possible, please add NFC to BJ v3.

    with that, may be we can replace yubico key with BJ v3.
    and use xxx pay, xxx door card with a single device?

    ps: google previously have titan key provied in NFC and bluetooth version.
