@marceloaqno said in Building a Orange Pi Gateway:

#define MY_RFM95_CS_PIN 13
#define MY_RFM95_IRQ_PIN 10
#define MY_RFM95_FREQUENCY RFM95_915MHZ

Thank you sooo much. I just did this. But, Now got a new error.

 ERROR Could not open /sys/class/gpio/gpio10/direction

and when I tried to export pin 10 it says:

:/sys/class/gpio# echo '10' > export
-bash: echo: write error: Device or resource busy

Though yes still I'm able to export/unexport pin 13(just for testing)

@pansen Thank you sooooooo much for your reply.!!! By the way, What I actually have to do is "Make an MQTT based LoRa(RA-02) receiver gateway on OrangePi Zero". And I'm stuck since whole week of course spent time trying code without solid base.
Yes, yet I'm trying to first set up a LoRa receiver(not MQTT, not gateway)

@pansen No.... nothing... /sys/class/gpio/gpio24doesn't exist.
even "echo "24" > /sys/class/gpio/export doesn't work.
But, yes otherwise if I try the same with 13 i.e "echo "13" > /sys/class/gpio/export Then a directory is created and then /sys/class/gpio/gpio24/direction do exist.

Am getting this error:
ERROR Could not open /sys/class/gpio/gpio24/direction
My config is:

./configure --spi-spidev-device=/dev/spidev1.0 --my-node-id=1 --my-transport=rfm95 --my-rfm95-cs-pin=13 --my-rfm95-irq-pin=10 --my-rfm69-frequency=915E6

Whole output is:
