lora网关如何开启和如何解决报错

BeyondDream

1 原理：SX1301 需要复位，才能正常工作。




2 实现代码：reset_lgw.sh 驱动 raspberry-pi GPIO 复位 SX1301

iot_sk_init() {
    # setup GPIO 26
    echo "$RASPI_SX1301_RESET_PIN" > /sys/class/gpio/export; WAIT_GPIO

    # set GPIO 26 as output
    echo "out" > /sys/class/gpio/gpio$RASPI_SX1301_RESET_PIN/direction; WAIT_GPIO

    # write output for SX1301 reset
    echo "1" > /sys/class/gpio/gpio$RASPI_SX1301_RESET_PIN/value; WAIT_GPIO
    echo "0" > /sys/class/gpio/gpio$RASPI_SX1301_RESET_PIN/value; WAIT_GPIO

    # set GPIO 26 as input
    echo "in" > /sys/class/gpio/gpio$RASPI_SX1301_RESET_PIN/direction; WAIT_GPIO
}


3 找到复位 GPIO 的序号，以 锐米通信的开源 LoRaWAN Gateway，该 GPIO 为 22





4 在当前路径下，执行命令：./reset_lgw.sh start 22
