[BUG] Wifi Scan doesn't seem to work on Lilygo C1101

[fromport]

Hardware: lilygo CC1101
Software: 0.5.2 (beta)

Describe the bug
Main menu : I select Wi-Fi -> get 3 options: Scan/ Sniff / Go back
I press Scan
see scanning take place, % goes to 100%, see all the different channels increase, ends with channel 13

Then Display shows "No network found."

Screenshot WifiAnalyzer app on android

I have many IOT devices on 2.4Ghz, have 3 AP's with 2.4Ghz
Go back to menu, click on "sniff"
On the screen
Sniffing packets...
Sniffed packets: 1
[save]

Count does not increase

To Reproduce
See above

Expected behavior
See a list of available SSID's.
I saw it once. but never again.

Same hardware - scanning works fine on my end.
I can scroll through the results just fine - would prefer to see a list of results though instead of having "cards" of each of them...

Hardware: lilygo CC1101
Firmware: 0.5.2 (beta) slightly more up to date though.

I just updated to the latest 0.5.2 beta (with the fix for #67 ).
Had to disconnect the battery so really from scratch, still nothing.
Could it be depending on the amount of AP's it finds ? could you overload the results ?

it seems to be a recurrent problem of ESP32. I don't find a real solution yet. I already do WiFi.disconnect(); delay() then start the scan but sometimes it stills fail(also to me).

Can you try this one? It use recommanded settings by EspressIf(shorten channel time)

This one seems better in my opinion. It implements a fix that I found on official Espressif Github and fixes a bug about GUI and WiFiScan that sometimes wasn't synchronized so that GUI printed "No networks Found" even if networks was found. (this version have a slower WiFIScan due to WiFI stack initialization)

While scanning it now "jumps" through all the channels (way faster then before) and I can see the result.
Nice!
I am going to try it a few more times and see if it will fo it all times.
So far I am really happy and impressed by your feedback and ability to fix things.
Thanks a lot !

UPDATE
After several power cycles/ suspend/resume it always shows output of the scan.
So for me, this issue has been resolved!
