Connecting to wifi occasionally failing

Postby srosca93 » Fri Mar 24, 2017 2:41 pm

I am running the latest AT firmware on my ESP32. Sometimes when I run the AT+CWJAP command, I get

Code: Select all

AT+CWJAP="invisible","12345678"

+CWJAP:0

ERROR
On the OS output from TXD0 and RXD0 I see

Code: Select all

I (35758) wifi: state: init -> auth (b0)
I (35763) wifi: state: auth -> assoc (0)
I (35775) wifi: state: assoc -> run (10)
I (35824) wifi: connected with invisible, channel 1
I (37237) wifi: state: run -> init (0)
I (37238) wifi: n:1 0, o:1 0, ap:255 255, sta:1 0, prof:1
I should note that this happens most often right after flashing the device. After several tries, it will comeback successful. Once it comes back successful once, it fails much less often.

Following is the full output from the ESP32 booting
