Pycom STA_AP scan not working

[Eckaard]

The board I'm using is a TTGO T-BEAN V1.1 and also a V1.0

The firmware I've tried are:

v1.20.2.r4-tbeamv1 v1.20.2.rc6-tbeamv1 v1.20.2.rc3-tbeamv1 v1.20.1.r2-tbeamv1

So my project goal is to build a collision detection system for vehicles. Each vehicle has a t-beam which constantly scans for surrounding Wi-Fi networks. Once a matching SSID is found, the RSSI is evaluated and the driver notified of his/her surroundings.

My issue is as follows; due to the fact that I need LoRaWAN, I've opted to use pycom firmware because it provides OTAA capabilities. My issue is I am unable to have a Access Point and Station at the same time as like with Micropython. My Micropython code looks as follows:

ap = network.WLAN(network.AP_IF)
ap.active(True)
ap.config(essid=ssid, password=password, channel=11, authmode=3)
while ap.active() == False:
  pass
print('Connection successful')
print(ap.ifconfig())

wlan = network.WLAN(network.STA_IF)
wlan.active(True)
while 1:
    available_networks = wlan.scan()
    for net in available_networks:
        if net[0][0:7] == b'mySSID':
            "do something"

When I declare my WLAN mode in STA_AP I get "OSError: Scan operation Failed!" with the following Pycom code:

import pycom
import network
pycom.wifi_on_boot(False)
ap=network.WLAN(mode=network.WLAN.STA_AP, ssid="hellooo")
wlan=network.WLAN(mode=network.WLAN.STA)
while 1:
        print(wlan.scan())

I am able to have an AP and connect to another network, however, the scan operation does not seem to work. I do not wish to connect to another network and thus connecting isn't an option.

Any advice or help would be appreciated.

Adding time.sleep(5) solved the issue. Unfortunately I have no idea why.

import time
from network import WLAN
wlan=WLAN(mode=WLAN.STA_AP, ssid="teste", auth=(WLAN.WPA2, 'passpass'))
time.sleep(5)
while 1:
        print(wlan.scan())
