Packet-forwarder unable to find _conf.json

[bi-sn]

I tried to create a miner. I used both ways. Balena deploy and then I tried to create my own release (both according to the guide in the readme) Both times I get the same error.

packet-forwarder ERROR: [main] failed to find any configuration file named global_conf.json, local_conf.json OR debug_conf.json

I use a Raspberry Pi4 with a RAK shield.

Hi,

open a terminal sesion to the packet-forwarder and copy both files from the sx1301 folder to /opt/iotloragateway/packet_forwarder

[mpous]

@Bjoerns-TB @bi-sn could you please try now to deploy the newest version? Let me know if you have any issue now!

@mpous Build fails [helium-miner] Step 12/14 : COPY keys.py . [helium-miner] COPY failed: stat /var/lib/balena32/tmp/docker-builder550136731/keys.py: no such file or directory

[mpous]

Apologizes for that @bi-sn i solved that! Try again!

[bi-sn]

Seems like it's still the original problem

[mpous]

@bi-sn are you using SX1301 LoRa concentrator? I haven't tried myself however try this VARIANT Device Variable --> https://github.com/NebraLtd/hm-pyhelper/blob/f8b2d8ceb90cfcd1da658a73e3741cc6de2ff1ff/hm_pyhelper/hardware_definitions.py#L223

[bi-sn]

Yes I use a SX1301. Changing the Variant into DIY-PISLGH did not change the outcome. Seems like the problem is: FileNotFoundError: [Errno 2] No such file or directory: 'opt/iotloragateway/packet_forwarder/sx1301/EU-global_conf.json'

[mpous]

i don't have right now with my a SX1301! i will test next week a SX1301 myself! apologizes for that @bi-sn

[shawaj]

@bi-sn what sx1301 concentrator are you using? do you have the exact model number?

[mpous]

@shawaj some people is using the RAK2245!

[bi-sn]

Oh .. I'm sorry I did not answer. Did overlook your Question. I use a RAK 2245 Pi Shield 868mhz https://store.rakwireless.com/products/rak2245-pi-hat?variant=39946145792198

[mpous]

@bi-sn is this the USB or SPI version?

[shawaj]

I don't understand why it's looking for the file at opt/iotloragateway/packet_forwarder/sx1301/EU-global_conf.json

It should be looking for it at /opt/pktfwd/config/lora_templates_sx1301/EU-global_conf.json

As per: https://github.com/mpous/helium-data-hotspot/blob/f54226a27179cf010319127beba03c8146434858/hm-pktfwd/Dockerfile#L42

It looks like from the debug output you have something overriding the SX1301_REGION_CONFIGS_DIR environment variable to an incorrect value:

SX1301_REGION_CONFIGS_DIR=opt/iotloragateway/packet_forwarder/sx1301

Have you set a fleet or device environment variable setting this value somewhere?

[shawaj]

P.S. our Nebra packet forwarder codebase definitely works with rak2245 as I've tasted it multiple times (including just today) so it must be a local issue with how you've deployed it @bi-sn

[bi-sn]

I'm puzzled. I don't know where the override came from but @shawaj is correct. I removed the override and it seems to work Thank you
