T-Beam RED LED under NEO Chip

What is the red LED under the NEO chip. It starts flashing (2x) then stops. In some cases the flashing keeps going for some time before starting.

I believe it indicates GPS status. Once you have gps lock it should pulse at a steady rate

it is for gps status.
When the gps locks on the satellites it flashes every second, it stops flashing when there is no gps signal
