Hi there, The error you provided states that the This is probably because you are using a version of Linux that has removed the sysfs interface for legacy calls to GPIOs, and the hal libraries provided by Semtech are not adapted for this change. In WM1302 module: step4 run semtech sx1302 packer forwarder it is indicated what to do when your Linux system does not have a sysfs interface (For Linux without sysfs interface:), to which you can refer for handling. Hope this will solve your problem! |

I am getting the same error with either process. To be fair I am attempting to get this to work with a RasPi 5. So it seems that my pins are set correctly. you are correct though this version of pios needed that and i did use that method but gave you more info here if that helps |

I'm not sure if there is a As far as I know, the newer Raspberry Pi OSes have now deprecated this way of calling GPIOs, I've forgotten exactly from which Raspberry Pi OS kernel version this was changed. You can try to control the GPIO using the commands provided by the Libgpiod package, here is a reference to SX1302_RESET_PIN=17 # SX1302 reset
SX1302_POWER_EN_PIN=18 # SX1302 power enable
SX1261_RESET_PIN=5 # SX1261 reset (LBT / Spectral Scan)
WAIT_GPIO() {
sleep 0.1
}
reset() {
echo "CoreCell reset through GPIO$SX1302_RESET_PIN..."
echo "SX1261 reset through GPIO$SX1261_RESET_PIN..."
echo "CoreCell power enable through GPIO$SX1302_POWER_EN_PIN..."
# write output for SX1302 CoreCell power_enable and reset
gpioset gpiochip0 $SX1302_POWER_EN_PIN=1; WAIT_GPIO
gpioset gpiochip0 $SX1302_RESET_PIN=1; WAIT_GPIO
gpioset gpiochip0 $SX1302_RESET_PIN=0; WAIT_GPIO
gpioset gpiochip0 $SX1261_RESET_PIN=0; WAIT_GPIO
gpioset gpiochip0 $SX1261_RESET_PIN=1; WAIT_GPIO
}
case "$1" in

exit 0You can also manipulate the GPIOs in other ways, just make sure that the pins associated with the WM1302 module are properly reset. |

Use the general-purpose IOs to control the SX1262_CS pin. |

Hi, Are GPIO6 and GPIO8 of the SX1302 available on some of the pins of the mpcie connector by any chance? They are necessary for libloragw to operate in interrupt mode but looking at the pin mapping table pin 6 (for GPIO6) and pin 28 (GPIO8) they look to be N/C. Other modules have it exposed on those pins and asking to see if it's exposed and not documented or simply not available in the WM1302 |

Alternatively that could be RX_ON (GPIO3) and TX_ON (GPIO5) that are sometimes exposed on LED_WLAN(pin 44) and LED_WPAN(pin 46) but they are also N/C on the seeed module |

yep, these are N/C on the WM1302, and from what I've seen, these GPIOs are typically N/C on other vendor modules as well |

@Jessie219-web thanks for confirming. Actually from what i've seen it's the opposite and other vendors have them exposed on the mpcie connector. Anyway if it's not the case it's not the case, it's just a shame as having access to those GPIO would be really great |

Hey, I'm using quectel ec25 and want to use EC25 GNSS port as an input to gateway so I modified the config file and gps driver (baudrate changed to 115200) but when I start the script there is # no valid GPS coordinates available yet# expression, so can anyone help? |

HI, However, when i replaced this US915 module with the EU868 module and using the same software at both endnode and gateway, I am seeing lorawan join accept message and lorawan join procedure is successful. ofcourse the rssi of the signals received at gateway is very bad (-100 dBm) as this is a EU868 module and signals are transmitted on US915 band. EU is a MCU version 01.00.00 and US version is V01.00.05 Is this a known issue on the US915 USB modules? |
