Does HL78 series support MQTT-SN protocol, or are there plans to support in future?

Hi jan.bogaert,

Currently, there is no plan from Sierra to support MQTT-SN on HL7800.

Thanks,

Hi Jerdung,

thank you for your quick response. Any other product which does support/plans to support MQTT-SN?  
Looking for NBIoT/CatM (band20) module.

Regards,

Hi jan.bogaert,

I would to say that I have checked all products on Sierra source page but there is no info about MQTT-SN.

Thanks,

Hi Jan

You could try the WP7702 module and implement the protocol on it’s application processor.

**Potential downsides**

- Cost
- power
- Legato learning curve
- boot time

**Potential upside**

- May be possible to implement a lot more in the application processor than just the protocol as it has a Linux + app framework OS
