nRF52832 DK and MQTT

[MeliodasD]

Hello guys.

Is possible integrate features from the IoT SDK to the BLE stack SDK?

I am planning use a Quectel cellular module attached to my nRF52DK and connect Azure over MQTT procotol, but I am not sure If the nRF52832 is enough for this task or the steps to integrate MQTT to the BLE SDK

Note: I am using SDK13 and SDK14 for my current aplication

Hi,

 

The IoT SDK, which is using the IPSP profile and has MQTT capabilities, was merged with the nRF5 SDK from v14.1.

The SDK includes MQTT decoder/encoder, as well as transport layers (TLS, socket, LwIP) and of course generic handling of the MQTT protocol (mqtt.c). As long as you port/write a transport layer conforming to your solution, that should work. I suppose you are going to fetch/send messages over both MQTT and BLE, so you'll need some application handling in addition as well to translate messages between the two protocols.

 

Best regards,

Håkon

Hi Hakon, inside the SDK what examples uses MQTT? I would like have a reference where to start :)

I am not planing using MQTT over BLE, I am going to use it thru an UART interface to a cellular module attached to the nRF52DK

This one uses mqtt: \nRF5_SDK_15.0.0_a53641a\examples\iot\mqtt

There's examples for both subscriber and publisher inside, based on lwip.

Cheers,

Håkon
