Trouble with LoRaWAN Gateway Module WM1302 + WM1302 Pi Hat

Products & Technology Raspberry Pi
#1

Hey,
I’m new to the Seeed family and I’ve been facing some challenges setting up a simple gateway using the WM1302 module with 1302 Pi Hat on a Raspberry Pi 4B. I’ve been following the instructions on the official Wiki page (LoRaWAN® Gateway Module WM1302 | Seeed Studio Wiki),

but unfortunately, I can’t seem to get it to work properly.

Following the instructions in the wiki, I enabled both SPI and I2C. Additionally, I changed the SX1302_RESET_PIN from 23 to 17 and the SX1261_RESET_PIN from 22 to 5.

I found that others faced the same issue in 2022, but I couldn’t find a solution for it. Hopefully, someone out there might be able to assist me.

Thank you in advance!

I had the same issue. I believe it it something to do with echoing out pins. After so searching around and chatGPT help I found that changing the way the resent pins get set is what fixed it for me (avoid echoing).

This is my reset_lgw.sh code:
(I am using WM1302/SX1302 so no need for the SX1261 reset lines)

  GNU nano 7.2                                                                                                                                                                        
# Usage examples:
#       ./reset_lgw.sh stop
#       ./reset_lgw.sh start
# GPIO mapping has to be adapted with HW
#

SX1302_RESET_PIN=17
SX1302_POWER_EN_PIN=18

reset() {
   echo "CoreCell reset through GPIO$SX1302_RESET_PIN..."
    
     gpioset gpiochip0 $SX1302_RESET_PIN=1
     sleep 0.1
     gpioset gpiochip0 $SX1302_RESET_PIN=0
     sleep 0.1

}

term() {
   # "unexport" (set back to "input" by reading its value)
   gpioget gpiochip0 $SX1302_RESET_PIN
}

case "$1" in
    start)
    term # just in case
    reset
    ;;
    stop)
    reset
    term
    ;;
    *)
    echo "Usage: $0 {start|stop}"
    exit 1
    ;;
esac

exit 0
