ESP32 Testing doesn't get past WiFi.enableSTA(true)

[renegadeandy]

I can't seem to get very far using the development branch.

Basic Infos

Using ESP32 dev board oooouuuu board.

Hardware

WiFimanager Branch/Release: Development

Hardware: ESP32

Core Version: 2.4.0, staging

Description

When I try to incorporate the dev WiFiManager into an old project which ran fine on esp8266, It seems to hang and crash directly after WiFi.enableSTA(true);

My call from main sketch is as follows:

 //Start WiFi Setup
  Serial.println("Setting up WiFi...");
  WiFiManager wifiManager;
  wifiManager.autoConnect("AP Setup", NULL);

The added Debug to autoconnect is as follows:

boolean WiFiManager::autoConnect(char const *apName, char const *apPassword) {
  DEBUG_WM(F("AutoConnect"));
 //digitalWrite(apLED,HIGH);
  // attempt to connect using saved settings, on fail fallback to AP config portal
    DEBUG_WM(F("2"));
  WiFi.enableSTA(true);
    DEBUG_WM(F("22"));
  _usermode = WIFI_STA;
  DEBUG_WM(F("222"));

Note my debug output is:

Setting up WiFi...
*WM: AutoConnect 
*WM: 2 

As we can see, we never hit the *WM: 22 message, The sketch appears to simply hang. Is there some kind of setup I need to do? Do I need to declare I am on an ESP32 to the library somehow?

Whats the debug from wifimanager???

[renegadeandy]

How do I turn that on? Not sure what you mean?

[tablatronix]

It should be on, unless you are setting it to off in your code.
It outputs lots of info

[renegadeandy]

I see no debug output at all in my code, apart from what i've shown to you above?

[tablatronix]

hmmm

[renegadeandy]

Ahh, well you see you never get past WiFi.enableSTA(true); so the rest of the debug output never gets executed!

[tablatronix]

ohh, well that is not wifimanager then, there is nothing in that function to get stuck, is your module crashing?

you should have an exception or something

[tablatronix]

enable esp debugging also maybe?

[renegadeandy]

No, although I have made a couple of alterations, and now I see

Brownout detector was triggered....

Wondering if this is a USB power problem...

[renegadeandy]

Yes! This was the problem, a really rubbish USB Hub, time to put that one back into the garage, sorry tablatronix!

[tablatronix]

Yeah power issue, below 300 ma or so, the wifi radio cannot turn on

[tablatronix]

added a catch for this

[renegadeandy]

Fantastic - thanks mate!
