downlink rssi could not be checked on the RPI side. it’s gateway side which sends downlink packet directly.
i measure downlink rssi from the node which receives the packet.
and i told you that i tried with another type of node which has sx1276, however, the problem still happened.
and if above happened, it should’ve shown different result when i changed gateway board with a new one, isn’t it?
Not necessarily.
You dont know for sure whether your seeing a hardware or a software problem.
but when i checked the quality of transmitter between two gateway device (RAK 831) (using util_tx_test), rssi value of received packet is good enough.
then it’s not cause of gateway device itself right?
uhm, guys… i don’t know why…
it just worked. I do not change anything but,
downlink rssi seems reasonable right now (-60~-80)
I did experiment for about 1 month, however, this problem was not configured.
But, today it seems fine. uhm, really strange.
