SDK Support for Malaysia Frequency Bands (919–923 MHz)

Hi,

I’m working with the MM6108 + MM-IoT SDK here in Malaysia. Our local ISM band is 919–923 MHz (as per Malaysia regulations).

Does the SDK already support a Malaysia (MY) region setting for this band? Or do I need to create a custom BCF to match the Malaysia frequencies?

Hi @Taz1

The OpenWrt fork or the MM-IoT-SDK?

We don’t have explicit support for Malaysia at this stage - and unfortunately our BCF modification tools won’t allow adding regions we don’t yet explicitly support. There’s a few other moving parts to adding a region including modifying the morse-regdb and making sure the driver has appropriate mappings (for Linux - see morse_driver/dot11ah/reg_rules.c at main · MorseMicro/morse_driver · GitHub)

In the meantime, it looks like Malaysia is a subset of the US so perhaps your best course of action right now is to artificially restrict the channels in the US driver regdom to prevent the driver advertising limits outside of the MY regulatory rules.

Hi @ajudge , thanks for the clarification

Just to confirm — we’re working with the OpenWrt .
Since Malaysia isn’t explicitly supported yet and the BCF tools can’t add new regions, we understand that the best option for now is to use the US regdom and manually restrict channels so they stay within Malaysia’s allowed 919–923 MHz band.

Appreciate the guidance.
