MMR sensor dont working

I have a problem with my MMR sensor.
Since I updated the firmware, the light does not turn on and does not connect to the Bluetooth.
Please tell me what can I do?

    This is actual normal. The light turning on is not the default behavior of the MetaWear.
    We put the wrong firmware on some of the late MMR boards.

    Do you prefer the version of the firmware where the lights turn on? We've been thinking about making that standard.
