This is most likely a misconfiguration

[dusk0r]

/sys/class/gpio is obsolete and was removed.

Replace following lines in start.sh:

# Reset iC880a PIN
SX1301_RESET_BCM_PIN=25
# REMOVE
#echo "$SX1301_RESET_BCM_PIN"  > /sys/class/gpio/export
#echo "out" > /sys/class/gpio/gpio$SX1301_RESET_BCM_PIN/direction
#echo "0"   > /sys/class/gpio/gpio$SX1301_RESET_BCM_PIN/value
#sleep 0.1
#echo "1"   > /sys/class/gpio/gpio$SX1301_RESET_BCM_PIN/value
#sleep 0.1
#echo "0"   > /sys/class/gpio/gpio$SX1301_RESET_BCM_PIN/value
#sleep 0.1
#echo "$SX1301_RESET_BCM_PIN"  > /sys/class/gpio/unexport

# ADD
pinctrl set $SX1301_RESET_BCM_PIN op dl
sleep 0.1
pinctrl set $SX1301_RESET_BCM_PIN op dh
sleep 0.1
pinctrl set $SX1301_RESET_BCM_PIN op dl
sleep 0.1

Would you have time to send a pull request with the fix?
