and what determines this ’ deduplication timeout '
… a lot of packets from that specific GW, is that possible, a ‘slow’ responding GW with a good rf signal ?
now I understand the following (a little bit) better :
during testing of this node firmware, I had one day my own gateway on, OTAA joining worked fine and when I switched my gateway off the packets were seen by 3 other gateways (sometimes only one)
next day, I had my gateway still off, I started the node again… no OTAA possible but join request visible in application ??
switched my gateway on, re started the node, no problem joining, switched off my gateway…
e voila… packets are seen by 3 gateways.
my conclusion sofar… always start your node close to a gateway
