Can someone guide with how to create own firmaware and modify the MAC layer of the device?

Hi @Anindita

What exactly are you trying to achieve here?

The firmware for the MM6108 is not user modifiable.

On a Linux device, you can modify mac80211 to adjust those parts of the mac layer.

For microcontroller based designs, our upper mac is bundled in a precompiled binary, libmorse.a. This is not currently user modifiable. Please see [GitHub - MorseMicro/mm-iot-sdk](https://github.com/MorseMicro/mm-iot-sdk) for building your own firmware with our SDK.
