Jetson TX1's WiFi controller can be run in Access Point (AP) hot-spot mode, enabling TX1 to host it's own WiFi network.

Setting Broadcom op_mode

To enable SSID broadcast, the driver’s op_mode parameter has to be set to 2.

This can be set in two ways:

  1. Manually via /sys/module/bcmdhd/paramters/op_mode node:
$ echo 2 > /sys/module/bcmdhd/parameters/op_mode
  1. Add the following line to /etc/modprobe.d/bcmdhd.conf:
options bcmdhd op_mode=2

Using hostapd

See the following guide to using hostapd service for running the Access Point: https://seravo.fi/2014/create-wireless-access-point-hostapd
