Hello Community,
For starters, I have a Chirpstack server running on an instance of Ubuntu. It runs perfectly, I managed to add my Dragino Gateway and controller .
For the Gateway part, I chose “LoRaWAN–Semtech UDP”. In the “Primary LoRaWAN Server” section I chose as follows: “Service Provider” → “Custom/Private LoRaWAN”, “Server Address” → “My ChirpStack server ip : port”. As I said above, it connected and works perfectly, managing to uplink from End-Node to ChirpStack via Gateway successfully.
The problem I encountered and am asking for help with is on the Downlink side. I found the downlink section in the Chirpstack server, called “Enqueue downlink payload”, where I selected the port, confirmed the donwlink, and in the “Base64 encoded string” section I entered the message: “Gg==” because after encoding I want my controller to receive the message “1A”. I managed to downlink once, after that whenever I wanted to downlink it didn’t work, regardless of the port or the message I wanted to send.
Later on, I managed to point the Dragino Gateway to a TTN instance, to try and with this platform to do uplink and downlink with the same Gateway and the same Controller. In this configuration: “End-Node → Dragino(Gateway) → TTN” worked perfectly and I was able to uplink and downlink.
Could you help me with a tip why I fail to downlink in the configuration “End-Node → Dragino(Gateway) → ChirpStack” ?
