It is not possible to use pip to download python packages

GL-SFT1200 Opal with the last firmware version: 3.215
I have installed Python and python-pip to be able to work comfortably with python but it has not been possible despite the fact that I have tried in several ways. Here is an example:

pip install paho-mqtt

pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
Collecting paho-mqtt

Have you installed python-openssl with opkg (or python3-openssl, depending)?

Thanks for your answer
Yes, I have installed python-openssl but it still shows the same errors
Regarding python3, python3-pip is not available in the official gl-inet repositories and I had opted to use python 2.7
It seems complicated to use Python with this device, I guess it’s because of firmware customization

SFT1200 is not powerful enough to run more heavy applications.

I have MT2500 which run pip
