My ESP8285 firmware is up-to-date, and I can't seem to use SSL with the latest firmware as the AT firmware crashes. Please see below:
>>> import network, machine, os
>>> wifi = network.wifi
>>> wifi.start(tx=7, rx=6, ssid="***REDACTED***", password="***REDACTED***", wait=True)
True
>>>
>>> wifi.ifconfig()

>>>
>>> wifi.debug(True)
True
>>>
>>> requests = network.requests
>>> requests.debug(True)
>>>
>>> res = requests.get('http://loboris.eu/K210/test.txt')

Welcome to K210
===============
General Specifications:
-----------------------
* The K210 includes two 64-bit RISC-V CPU cores, each with a built-in independent FPU.
* KPU high performance Convolutional Neural Network (CNN) hardware accelerator.
The primary functions of the K210 are machine vision and hearing,
which includes the KPU for computing convolutional neural networks and
an APU for processing microphone array inputs.
* The K210 features a Fast Fourier Transform (FFT) Accelerator for high performance
complex FFT calculations. As a result, for most machine learning algorithms,
the K210 has high-performance processing power.
* Advanced TSMC 28nm process, temperature range -40°C to 125°C
* Firmware encryption support
* Unique programmable IO array maximises design flexibility
* Low voltage, reduced power consumption compared to other systems
with the same processing power
* 3.3V/1.8V dual voltage IO support eliminates need for level shifters
