Hi,

My local_conf.json in my multitech conduit is:

But I receive this in the log file:

09:14:00  INFO: [down] a packet will be sent in "immediate" mode
09:14:00  ERROR: Packet REJECTED, unsupported frequency - 869525000 (min:0,max:0)

Why ?

Thanks.

This should be in global config, not local. And for TTN you need to download that global config from TTN.

Yes,

I’m trying to edit the Original global_config… but i need to remove “global_config_src” ? If not, after restart the service global_config is replaced.

Imagine that I need to use ttn-pkt-forwarder like the original of multitech. What is the file to edit the url to the server ? local ? global ? ttn- ? multitech_over… ? ?

Device specific settings should be in local_conf.json. General network settings in global_conf.json.

You should never need to edit global_conf.json.

I think that downstream is ok, but upstream is allways 0…

TTN protocol does not use those stats.
