Gateway 7289C packets lost

Hi everyone.
I’m using 7289C gateway in a Lora packet forward mode.
I noticed that some packets are lost when the device and gateway are near to each other (in few meters).
In debug mode I see that the packet was sent to the gateway, but it was not delivered to the lorawan server. What should I do to make it stable? As far as I understand, I can sent the packets with ack but it will increase energy consumption. Are there any ways to make it more stable?

Hi Sergey,
I’m having a similar issue, have you found a solution yet?


Not exact but the recommendations here is to turn the frequencies. As far as understand, using SF-7 should work better on short distances.
