FSPI - Fast SPI. The prefix of the signals for GP-SPI2. FSPI bus signals are routed to GPIO pins via either GPIO matrix or IO MUX

Thank you.
Neither chatGPT, Grok, or myself found that.
However that doesn't answer the other half of my question.
Is it ...

FSPI is used often in the documentation and there is no clear definition.
Could someone at Espessif please explain it.
The schematics don't show it connected to any flash on the wroom units.
Can these be used as general purpose pins and if so what are the restrictions or advantages of FSPI.
Thank ...

Hi

I code in C so C++ may be a little different.
Also I am on linux so for others the COMMAND line will be different

Anyway I wanted a base timeline that was the absolute last build time every time I compiled
other methods give the last full compile time which can be quite old.
I also wanted it ...

I have now added this to my generic code to make the errors a little more clear.


const char *wifi_reason_to_name(wifi_err_reason_t reason)
{
switch (reason)
{
case WIFI_REASON_UNSPECIFIED :return "1, Unspecified reason";
case WIFI_REASON_AUTH_EXPIRE :return "2, Authentication expired ...

Hi,
You posted code the way you stop wifi, but not how you init and start wifi.

Also, if your code and logs are more or less standard then disconnect reason 201 means the AP cant be discovered.


Thank you I did find the error elsewhere in the code where the AP details were stored incorrectly ...

To be complete here I will add this

time_t compile_time()
{
char source[40];
time_t t = 1736287200; // Error case
#ifdef BUILD_TIME_UNIX
sprintf(source, "BUILD_TIME_UNIX");
t = (time_t)BUILD_TIME_UNIX;
#else
struct tm tm_info; // A struct to hold the time information
char datetime_str[30 ...

Hi,
i have reasons asking you to show wifi init code, which i will explain later.
There is last one question:
- when you stop wifi with this function, which one is next to restart wifi and it fails?
esp_err_t wifi_stop(void)


that would be either of these


//! SNTP functions

esp_err_t sync ...

Hi,
You posted code the way you stop wifi, but not how you init and start wifi.

Also, if your code and logs are more or less standard then disconnect reason 201 means the AP cant be discovered.

Thanks for your interest but if it is working fine on a cold boot but not after my code why do you ...

HI
In esp-idf I have the following shutdown code.

esp_err_t wifi_stop(void)
{
CHECK(esp_wifi_stop());
CHECK(esp_wifi_deinit());
CHECK(esp_wifi_clear_default_wifi_driver_and_handlers(STA_netif));
esp_netif_destroy(STA_netif);
CHECK( esp_event_loop_delete_default());
STA_netif = NULL;
return ...
