Dragino PG1301 & RPI 3B+: How to find gateway ID

1

Dear TTN-Fellows,

I have purchased a Dragino PG1301 along with a Raspberry Pi 3B+. I followed the installation guide, the status prompt gives me the following output:

pi@raspberrypi:/etc/lora $ sudo systemctl status lorapktfwd

I would like to find out the ID of my gateway, this command gives me no feedback:
ifconfig eth0 | grep eth0 | awk ‘{gsub(/:/,"");print $5"ffff"}’

Best and thank you!

I forgot: using the gateway-id reported in /etc/lora/local_conf.json
doesn’t work (as described in the manual). Trying to register it at TTN reports the error gateway ID already registered.

You may be hitting a hard-coded default which would already have been used by someone else.

Try creating a new gateway id, putting that in the config file, rebooting the gateway, and registering that.

sudo ifconfig should give you some manual clues to the MAC address of at least some interface on your pi and then you can apply the appending rules; to an extent it doesn’t really matter what the id is, as long as it is a hex string of the appropriate length and globally unique

There’s probably some guidance around somewhere on the best way to “invent” one if there are no hardware details to start from.

You may use the Dragino Package as below:

wget http://www.dragino.com/downloads/downloads/LoRa_Gateway/PG1301/software/lorapktfwd.dep

Then, it runs

sudo dpkg -i lorapktfwd.dep

After that, you need to adust your locar frequency plan as the below directory

sudo cp ???-global_conf.json …/global_conf.json

Finally you must run the below commands:

sudo sytemctl start lorapktfwd

sudo journalctl -u lorapktfwd -f

Good Luck!

You can use below command to generate an unique ID from the raspberry MAX address of eth0

ifconfig eth0 | grep ether | awk ‘{gsub(/:/,"");print $2"ffff"}’
