Hey,

I am trying to get a simple http request working by following the http_example. I installed everything necessary, configured the SSID and Password and uploaded the app to my Sparkfun esp32 thing.

The result is not what I would expect. It connects to the WiFi without issues but gets stuck doing the http call.

Code: Select all

I (308) example: Setting WiFi configuration SSID ASUS...
I (318) wifi: mode : sta (24:0a:c4:04:f4:54)
I (438) wifi: n:1 0, o:1 0, ap:255 255, sta:1 0, prof:1
I (1098) wifi: state: init -> auth (b0)
I (1098) wifi: state: auth -> assoc (0)
I (1098) wifi: state: assoc -> run (10)
I (1318) wifi: connected with ASUS, channel 1
I (2918) event: ip: 192.168.178.90, mask: 255.255.255.0, gw: 192.168.178.1
I (2928) example: Connected to AP
I (2948) example: DNS lookup succeeded. IP=93.184.216.34
I (2948) example: ... allocated sock�t

��B���J*�	�
                 ��'$��	Ҷ�˫�W��+L[C��+��&�[R��3p88) example: .\. soí�с������Ս����m��u5R�

On another try:

How can I debug further or has anyone an idea what the issue could be? Somehow it gets stuck... But I have no clue why

Hey @ManuelS,

Basing on randomness of output and when it happens, this looks like some h/w problem.

Did you manage to successfully run other examples?

I would try the following examples and check for healthy output on UART:
1. get-started/hello_world
2. protocols/sntp
