Gateway with legacy package forwarder not connected

[rmh78]

My raspberry gateway uses ttn-resin-gateway-rpi
I configured it with balena (resinIO) environment variables to use the legacy package forwarder only.

SERVER_TTN = false
SERVER_0_ENABLED = true
SERVER_0_TYPE = semtech
SERVER_0_DOWNLINK = true
SERVER_0_ADDRESS = router.eu.thethings.network
SERVER_0_PORTUP = 1700
SERVER_0_PORTDOWN = 1700
FREQ_PLAN_URL = https://account.thethingsnetwork.org/api/v2/frequency-plans/EU_863_870

But my gateway shows offline in the TTN console.
My LoRa node uses OTAA to connect but I only see activation messages in the TTN console, no uplink, no downlink messages.

The only special log-entries I found in the package forwarder logs where these:

Upstream datagram acknowledgment quality for server “router.eu.thethings.network” is 0.00%

WARNING: [up] ignored out-of sync ACK packet

The ttn-resin-gateway-rpi uses the multi-protocol-packet-forwarder.
Is it not possible any more to use this forwarder in UDP/1700 mode?

Your log shows you are using it in that mode and it is sending data to TTN, so why ask?

[rmh78]

First i’m asking because it does not work.
But no data arrives and the gateway is shown offline in the TTN console.

Second i read on github for ttn-resin-gateway-rpi.
So i am not sure if this new data-format works correct with the old UDP.

mp-pkt-fwd uses the new protocolbuffers-over-mqtt-over-tcp protocol for gateways, as defined by TTN and used by the TTN kickstarter gateway. Using this protcol the gateway is authenticated, which means it is registered under a specific user and can thus be trusted. Because it uses TCP, the chance of packet loss is much lower than with the previous protocol that used UDP. Protocolbuffers packs the data in a compact binary mode into packets, using much less space than the plaintext json that was previously used. It should therefore consume less bandwidth.

1. The log shows data is arriving and being forwarded. Did you register the gateway in ‘legacy’ mode @ TTN?
2. MP stands for Multiple Protocol. IT implementatie both the UDP based protocol and the newer, better TCP based one. So you can decide which one to use.

[rmh78]

I registered a new legacy gateway with the mac-address of the raspberry and also set the environment variable GW_EUI to the mac address. Then the gateway showed up online

My device tries to join via OTAA. The joining request and join accepted messages were displayed at the TTN gateway console. But the downlink message (accepted join) does not arrived at the device. So my device was not able to successfully join via OTAA.

I switched to ABP and I was able to send uplink messages. But downlink messages are not working.
So my next challenge is to fix downlink… My gateway is configured with GW_DOWNSTREAM=true.
Any ideas??

[kersing (Jac Kersing)]

Take a look at the gateway log to see if it actually gets and transmits the data TTN schedules for transmission? Use SDR to check if the gateway transmits any data? Check the node debug to see if it gets any data? Make sure your node is not to close to the gateway (at least 3m distance)?

READ THE FORUM to check for answers as this question (node activation fails) and how to proceed has been answered at least once earlier this week? (That allows me to spend time helping people with unique issues)
