reset_lgw.sh

in ESP32 & Lora

Hi all,
I bought an LR1302 with a RPI HAT in order to design a LoRa gateway.
After software installation, i run ./chip_id command in order to get the gateway ID.
Unfortunatly the reset_lgw.sh failed because /sys/class/gpio is deprecated.
I replaced the echo command by a gpioset command as a char device is now used for the gpio in the linux.
See example below

echo "1" > /sys/class/gpio/gpio$SX1302_POWER_EN_PIN/value; WAIT_GPIO

gpioset gpiochip0 18=1

Unfortunatly the chip is not detected even though the gpio seems to toggle as expected.
Indeed i get the following message:
cleanup all GPIOs
setup GPIOs...
CoreCell reset through GPIO17...
SX1261 reset through GPIO17...
CoreCell power enable through GPIO18...
CoreCell ADC reset through GPIO13...
Opening SPI communication interface
Note: chip version is 0x00 (v0.0)
ERROR: Failed to set SX1250_0 in STANDBY_RC mode
ERROR: failed to setup radio 0
ERROR: failed to start the gateway
Just for info the GPS is functional (tested with minicom -D /dev/ttyS0 -b 9600)
Any help will be appreciated
Regards,
PS: It could be a good idea to update the lora repository with the support of the new gpio system. On the hand i don't managed to understand the matching between the gpio driven in the script and the gpio mapping indicated in the documentation.

    Hello greg, which version of Raspberry Pi system do you use? For now, it only supports version Buster.

    Hi,
    Thanks for your feedback.
    cat /etc/os-release

    I tried with buster but unfortunately i get the same result
    See below when i issue the ./chip_id command:

    pi@MAPI4:~/LR1302_loraWAN/LR1302_HAL/sx1302_hal/util_chip_id $ ./chip_id

    I think there's a problem with the hardware.
    Any idea ?
