How to generate TX signal with power -6dBm

[bangdracaena]

Dear support team,

To get CE certification, We need to test module LORA EU868 again. However, we're troubled with generating TX signal with -6dBm

I had run command: sudo ./test_loragw_hal_tx -f 868.1 -r 1250 -m LORA -n 10000 --pa 0 --pwid 10 -s 7 -b 125 -p -6-z 255 -l 65535 -t 50 -u -d /dev/ttyACM0

But the TX power can't decrease to -6dBm

Thanks and waiting for your response.
