I can't seem to stabilise the most common wifi STA code. I have multiple result.
Connect fast and work,
Connect very slow and work
Random very fast hang
Random hang after some time
Ramdom crashes very fast
Random crashes after some time

Random hang after some time, No Crash :

Any ideas what is happening ?
Getting frustrated.

Hi enitalp,

Thanks for letting us know about this.

Can you please post the source code you're running here?

Do you get any warnings about out of date submodules when you run 'make'?

Strange thing, the more i use my esp32, the less i'm able to use wifi. It's been a few hours since my last successfull connection.
And the more i get garbage in my log.

I Start to suspect highly my hardware, saw a lot of people complaining about the same thing with the SparkFun Thing, Ordered Some brand new esp Wroom32 dev card yesterday evening. Hope to get different result.

Last Log : Instant death.

Ok i can confirm 2 things.

I'm not able to use wifi anymore without stalling the esp in the last 8 hours without any code change.
I switched to my second esp32, and 4 secs later was connected to the wifi without any garbage in the log or crash, or stall with the same code. So it's not a code problem but a hardware problem. I've read some people having the same kind of problem using the Sparkfun esp32 thing. It's either a design problem or those board are using a beta version of the esp ?

At least it's not the sdk or my code ;p
