9.3 Can I make my own firmware for the gateway, where can I find the source
code?
Yes, You can make your own firmware for the DLOS8 for branding purposes or to add customized
applications.
The source code and compile instructions can be found at:
https://github.com/dragino/openwrt_lede-18.06
9.4 Can I use 868Mhz version for 915Mhz bands?
It is possible but the distance will be very short, you can select US915 frequency band in 868Mhz
version hardware. It will work but you will see the performance is greatly decreased because the
868Mhz version has an RF filter for band 863~870Mhz, all other frequencies will have high
attenuation.
9.5 Can I control the LEDs?
Except the PWR LED is controlled by +3v3 power directly. All other LEDs can be controlled by
developer.
Control Globe LED:
ON: echo 1 > /sys/class/leds/dragino2\:red\:wlan/brightness
OFF: echo 0 > /sys/class/leds/dragino2\:red\:wlan/brightness
Control HEART LED:
First export the gpio27 and set to out
echo 27 > /sys/class/gpio/export
echo out > /sys/class/gpio/gpio27/direction
ON: echo 0 > /sys/class/gpio/gpio27/value
OFF: echo 1 > /sys/class/gpio/gpio27/value
