- Mon Jan 04, 2016 10:31 am #37885 Hi

I try to follow this tutorial : https://learn.adafruit.com/esp8266-temp ... r/overview

I achieve to upload the code to my esp8266-01 without issue.
But when i reboot after flash mode, my serial monitor stay at "Working to connect".

I check ssid and password, but even after reupload, reboot, still stuck at this point.

Any ideas how to debug wifi connexion issues ?

Thank.

Possible causes:
Wrong ssid or password
Wifi not receiving
Bad 3.3 volt power to the EPS01

I use my phone hotspot to test with simple ssid and password : freebox / test-test.

I put my phone close to my esp8266.

For the power, i use 12v to 5/3.3v, one like this :

Jumper is on GND/3.3

What's strange is that once i was connect to my phone (i can access to my temperature) but after reboot to test without ftdi, it doesn't work anymore even if i reupload.

Code: Select allConnecting to freebox
