# GPIO access

## Question

Asked by leventelist on 2017-03-30 in Wireless.

I want to access GPIOs of the module. When I say:

echo “19” >/sys/class/gpio/export

I get:

-ash: write error: Resource busy

This is with a recent, clean install of LEDE, but I have similar results with OpenWRT.

What do I miss?

Thanks,
Lev
