LoRa Gateway Not Receiving All Messages


up until now I have been sending messages with one node only and I had no problems with loosing packets.

It was time for me to change that to 19 nodes. Before I did that I wanted to test my program for data analysis with 2 nodes, so I started sending data to LoRaServer with 2 nodes only.

What I found out was that not all messages are even received by GW / published to MQTT.

Both nodes have fixed parameters:

  1. SF7 BW 125 Freq 868300
  2. SF8 BW 125 Freq 868500

Anybody with same problems?
Duty cycle is disabled.

The GW consists of:
