Bitrate of encoded frame

Hello,

I built opus 1.3.1 for ARM Cortex-M4 and will send opus frames via IEEE802.15.4.

I need a little length of the encoded packet. Actually I have 48kHz, 16Bit, Mono, framesize 960 input to 8kHz output and get 320 Byte (CBR) output of encoded frame. I tried to change the BANDWIDTH and APPLICATION but is still the same length of the encoded packet.
I don't understand why the bitrate is the same?
Can anyone help me?

Bitrate is controlled by BITRATE, VBR, and VBR_CONSTRAINT. Try adjusting those.

Packet or frame?  Not the same thing.
