My lorawan gateway can’t control its reset gpios via the sx1302_reset_chip and sx1302_reset_pin settings in the toml file, so my idea is I can do that with the reset_commands. But how can I do that? I tried reset_commands=[["./reset_lgw.sh", ["stop"]],["./reset_lgw.sh", ["start"]]], but it seems nothing happens.
I am using concentratord v4.4.5, these are my logs. And I can’t find Configuring raw reset commands from it, which means the reset commands aren’t executed.

What is your gateway and what commands are needed to reset the SX1302?
I am using a seeedstudio sensecap gateway, and I normally use the sysfs interface to control the reset pin, like this:
echo "1" > /sys/class/gpio/gpio$SX1302_RESET_PIN/value; WAIT_GPIO
echo "0" > /sys/class/gpio/gpio$SX1302_RESET_PIN/value; WAIT_GPIO
The reason that I can’t use the chardev interface to control pin is the kernel version is too low:
~$ uname -a
Linux sensecap 4.9.80-ti-r98 #1 SMP PREEMPT Wed Feb 7 01:23:46 UTC 2018 armv7l GNU/Linux
# gpio0-22 is the reset pin of 1302, but I can't control it
~$ gpioinfo 0 | grep "line 22"
line 22: "GPMC_AD8" "P8_19" output active-high [used]
~$ gpioget 0 22
gpioget: error reading GPIO values: Device or resource busy
The best solution would be to add support for the SenseCap gateway directly into the Concentratord. Unfortunately, I do not have this gateway in my office, but if you like to work on this and create a pull-request, then you could take this as an example: chirpstack-concentratord/chirpstack-concentratord-sx1302/src/config/vendor/multitech/mtcap3_003e00.rs at master · chirpstack/chirpstack-concentratord · GitHub.
