MQTT publisher on NRF52 using W5100

[Renato Silva]

Hi!

I am developing a iot solution and I wanna send sensors data to broker by MQTT publisher.

In my code already has the W5100 development and now I want to connect my device (nRF52)  on broker taht I installed on virtual machine.

Are there any library for I add on my project segger, connect to broker and send these informations?

I did study the example presents on SDK iot, but that example require many configurations (mainly IPv6) and I need a solution more simple.

HI Renato, 

I am afraid that we do not have any other MQTT examples in our SDK than the ones using IPv6. The reason for using IPv6 is that the header can be compressed so that it can be fitted within a BLE packet.

Hi Bjorn,

I installed a mqtt broker (mosquitto) on a virtual machine, running ubuntu 16.

This broker has an IP(v4/v6), an user and a password.

Can I adjust the mqtt pub example to send data to this broker? Which changes I need in the code to do for it?

I asked for other alternative becausa I am difficult in to run the ipv6 tools as IPv6lowPan.

All the steps necessary to connect the MQTT publisher example in our SDK to a Mosquitto Broker on a Linux machine with BLE HW (either embedded or a BLE dongle) should be explained on this page
