Frame counter for downlink

Hello guys, I configured my device in abp. Checking the frame counter for downlink is incrementing together with uplik. I would like to know if it is normal?

why not? if endnode packet needs to be confirmed then for each uplink downlink ack is emmited

The strange thing is that my ack is disabled!!! I use lmic

look into live frame tab for debugging.

what affects the downlink is rx1 data rate offset. above 6, the downlink frame count does not follow the uplink count. however, when I send a command the device does not receive it. it also happens in Chirpstack OS
