Now wifi won't work

Hi all,

I have been successfully using WiFi for some time, but with the latest SDK I now see:

Code: Select all

W (1031) wifi: wifi nvs_open fail ret=4353                                      
                                                                                
E (1031) wifi: wifi_init 1191 ret=4353

I thought it might have been something to do with the new storage of PHY calibration data in NVS, but disabling that made no difference.
What do I need to do to prevent this please?

Regards,
Murray

I am presuming you are calling esp_wifi_init() and it is returning a value other than ESP_OK. What I would suggest you do is capture the numeric value that is returned in a variable and then log that variable. That will give us a clue as to what return code is being returned. Also, the esp_wifi_init takes as input a structure (if I remember correctly). It is possible that there is an error in the input data being passed into esp_wifi_init() ... so you might want to post the values passed in.

If you have just changed environments, consider deleting sdkconfig file and rebuild a new one by running "make menuconfig".

Also consider completely erasing flash memory on the ESP32 using the esptool erase_flash command.

Can you add a call to nvs_flash_init() before calling esp_wifi_init?
Also do keep "store calibration data in NVS" option enabled for now.

Hi Neil,

The code was working for some time as is, and I ran make menuconfig (I was forced to by the SDK update anyway). I'll try erasing the flash.

Hi iggr,

I tried adding nvs_flash_init() when I remembered about the new PHY nvs param storage setting, but that didn't fix it. It's late here now, but I will follow suggestions tomorrow and report back.

Lucky you, you get an assert at least.

Since yesterday i'm dealing with the same problem, but i do crash.
Changing to store phy calibration fixed my crash. thanks for the tip,

FYI here is my crash before

Sorry fellas,

I added nvs_flash_init() to one of my tasks by mistake instead of main. Tired and rushing.

All good now.

Many thanks,
Murray
