MQTT Client over BLE, possible using nrfConnect SDK?

Question

Hello 
 
 I would like to build an application that will publish data to an MQTT broker. I found the MQTT Client - Publisher Example, that shows how to build a BLE MQTT clients, but it is for the nRF5 SDK v16.0.0. 
 I would like to ask if it is possible using the nRF52840 processor, to build a BLE MQTT client that publish data using an external BLE enabled router. 
 So the setup would be, connect the nRF52840 using Bluetooth to a router (with an internet connection) and publish data to an MQTT Broker. 
 
 Thank you

Hi Avgerinos89, 
 As explained previously, we chose Thread as the alternative to 6LoWPAN over BLE; and I found some recent info about MQTT over Thread. 
 In the nRF Connect SDK (NCS)'s Thread solution, UDP is already supported, and TCP supported is experimental. A complete sample solution is not available, but it is possible to setup MQTT-SN over UDP, or MQTT over TCP with this. 
 Here is a DevZone answer on the topic of MQTT over Thread that might be of interested to you: RE: Publishing MQTT messages from Thread device using NCS .
