This ticket is the continuation and related to the previous ticket on the matter:

Here is the full project in this link:
(note: the link has a 24H expiry date)
The way I build and flash is:
- navigate in terminal to /Users/tudor/Documents/GitHub/micropython_nrf/ports/zephyr
- run this command once: west build -b nrf7002dk/nrf5340/cpuapp/ns --pristine
- run this command 2-3 times to make the build succeed: west build -b nrf7002dk/nrf5340/cpuapp/ns
- then flash normally with: west flash
To run the connection: open the usb serial and this should bring the MicroPython REPL up. Example of normal startup:

In REPL, run the commands:
import sock_test sock_test.do_steps()
This executes the function inside the python file located at: /Users/tudor/Documents/GitHub/micropython_nRF/ports/zephyr/modules/sock_test.py
That file is designed as a script that essentially emulates the behaviour of the of the https_sample since it connects to the WiFi, gets DNS address, brings up a socket and connects it to google.com and then tries the request from line 79:
httpreq = 'HEAD / HTTP/1.1 \r\nHost: '+ host +":"+ str(port) +'\r\nConnection: close\r\n\r\n'
Note:
Lines 27 and 29 are very important:
# wlan.scan()
wlan.connect("TP-Link_7474", "55920322", network.SECURITY_PSK, 4)
Scan is there and commented since for wlan.connect() you need to provide the channel number as the final parameter.
