Spamming downlinks to Dragino's LT-22222-L?

Hello,

I’m wondering if I could use LT-22222-L to control lighting alongside occupancy sensors.

When I send a downlink turn on/off command, the response time is really quick - it hardly takes a second. But not all downlinks make it to the controller. I’m noticing that out of every 10 downlink commands, 1 might not make it.

So as a workaround and to ensure all downlinks get through, I’m considering sending 3-4 downlinks (unconfirmed) in a timespan of 3 seconds so there’s a very high likelihood that no command will be missed. However, I’m not sure if LT-22222-L is capable of processing these many downlinks over 3-4 seconds. Do you think this is viable? Will it spoil or have any negative effect on the device? Is there a recommended minimum time gap between downlinks? Has anyone used LoraWAN to control lighting, etc. based on occupancy (where response time needed is less than 3-4 secs)? If I spam confirmed downlinks, will the ack uplink collide with the next downlink?

Thanks.

Just set your downlinks to confirmed instead. That way it will only send another downlink if the device doesn’t respond to the first one.
