I am planning frequency at AS923 profile. The node (iam using rak811) joined to chirpstack server with rak831 gateway easily but the downlink created with restapi still not recived. I checked log at gateway it showed some thing below, and the tx led was on when send downlink!
I don’t understand why?? because when joinning network (otaa/abp) the downlink is received to confirm the node join successfully.
The different things i seen is datarate: the downlink with SF10 is not recieved, i cannot change to SF7 or SF8 because it totally base on app server. Anyone find the solution for me
