Did Nordic SDK support ZIP compress/uncompressed to a string/payload? If possible to compress a raw string to .zip format. if so, which library and API function should I call?

Hi, I am a MCU developer searching BLE MCU to develop some IoT project.

I would combine nRF series and LTE NBIoT module for IOT project.

And I need to integrate many different cloud platform into MCU.

Usually using MQTT and JSON format.

But some cloud platform required zip format in data payload.

So I am searching if any ARM Cortex M4 could support zip / unzip function in their SDK

Some suggestions here:

(I just googled "zip microcontroller")

then maybe they aren't really targetted at this type of application?

I have tried to find some source code in gibhub for zip on MCU.
https://github.com/pfalcon/uzlib

And maybe I would try it first.

Cloud platform usually connect with a Linux based Gateway/ smart phone/ PC. And they have good support from ZIP compression

But in our device is a small dongle which is containing a low powerful MCU and it works for delivery some sensor data.

So we have many application require to integrate network protocol or data transfer. That's why I am searching zip compress in MCU
