MQTT with old Mbed version (1.8.3)

garrettb123

Hi

I have taken over a legacy project

C application running on NXP LPC4088 microcontroller
Mbed OS version (according to mbed cli): 1.8.3
Keil uVision version: 5.37

The application uses cellular network to connect with a TCP server.

Requirement:

I need to modify this project to connect and communicate with an MQTT broker.
- This is for existing modules in the field

I am struggling with what the first steps should be!

1. Is there an Mbed MQTT library that will work with this old Mbed OS version?
2. If there is, which version is it, how do I install it, and are there any examples
3. If there isn’t, can you suggest a path forward?

Thanks in advance for any help / suggestions

Garrett
