Hey, I loaded the SendOTAA example in the ‘the things uno’ and made it send a byte every 10 seconds. The problem is that my gateway only receives 15% of the messages i send. Can someone help me with this? Thanks already, Kobe

Describe your setup a little more. What gateway are you using ? 15% suspiciously looks like 1/8 : maybe you are using a single channel gateway and your node is sending on all 8 channels ?

Thanks for the quick answer. My gateway is a raspberry Pi with the dragino LoRa/GPS hat, using the software from the github page of bokse001. This way the one way gateway can work in two directions. (to be precise, it is 15,77% (counted over 600 messages))

The Dragino LoRa/GPS Hat is single-channel, so @DeuxVis ’s suspicion is likely correct.

ok, thanks. Do you have any advice on what gateway i should use instead? I’d rather not use the original one because I want to be able to modify hard- and software. I’d prefer a raspberry pi shield… edit: Or could I change a setting in the uno so it only transmits on one channel? Thanks for the h…

You could look at a RAK831 gateway module with an adapter board to go between the Pi Zero and the RAK831 module. One such adapter by Charles Hallard, one of the TTN contributors, is here: https://github.com/hallard/RAK831-Zero

I am using the sdk as provided by TTN.

Only 15% of messages arives
