Unable to OTAA Node With ChirpStack Server

Nabreet_Ghumman · March 21, 2020, 7:23pm

I am Not sure what am I doing wrong.
I am using Arduino Nano with the Sx1276 Lora chip and Rak7244 Gateway. ChirpStack Gateway-bridge, Network Server and App server are installed on a Ubuntu server.

Do I need to check Gateway, Node or OTAA Keys?

Yes, you’re need to check packet forwarder, why it not send the join accept to your endnode. also check the endnode regional frequency settings.

I am Using Arduino LMIC Library. Uplink and Downlink are both 915mhz frequencies, so I think i am on right frequencies. But i’ll check the packet forwarder and post the update. Thanks

It is Still not working here is my Gateway Bridge log

eugenev · March 22, 2020, 6:39pm

log about nothing.
I ask You to check the packet forwarder, not bridge

Nabreet_Ghumman · March 22, 2020, 7:37pm

Is this the one you are asking for?

eugenev · March 22, 2020, 7:51pm

no. this is tcpdump
which packet forwarder you’re using? learn the docs regarding packet forwarder and inspect the pf log output

P.S. please, do not use the screenshots, they are not readable, just cut and paste the plain text.

I am using Semtech Packet Forwarder. Following is its log file
