Hi there,
I’m facing a problem. Some ACK are not received by the node, mainly when this is far from the gateway (4km or more). In the Lora server I can see that all the uplink packets are received by the gateway and this send back the ACK. In some situations, the Gateway received the 8 uplink packets but the node doesn’t receive any downlink packet.
I believe the problem is related by any desynchronization caused by the distance.
I’d appreciatte any hint!
Thanks in advance
