【SOLVED】LIGHT SLEEP ERROR SDK 1.5.4

[irvinvp]

I'm trying light sleep, but the second time always shows a "fpm 737" Error, my code:

void sleeping(void);

void wake_up_func(void)
{
wifi_fpm_close();
wifi_set_opmode_current(STATION_MODE);
os_printf("ON\n");
sleeping();
}
void sleeping(void)
{
wifi_station_disconnect();
if(wifi_set_opmode(NULL_MODE)){os_printf("Null OK\n");}
wifi_fpm_set_sleep_type(LIGHT_SLEEP_T);
wifi_fpm_open();
wifi_fpm_set_wakeup_cb(wake_up_func);
os_printf("SUP: %d \n",wifi_fpm_do_sleep(60000000));
}
void user_init(void)
{
uart_init(BIT_RATE_115200,BIT_RATE_115200);
sleeping();
}

please use "wifi_set_opmode(STATION_MODE);" instead of "wifi_set_opmode_current(STATION_MODE);" in function "wake_up_func(void)"

Ok thank you very much, it is solved

I'm having the same issue, Is this issue going to be fixed with the next SDK version?
It would be nice to use "wifi_set_opmode_current()" since it doesn't write to flash.

[ESP_Rubin]

yes,we have fixed the issue in next SDK.
and for old SDK, we suggest use"wifi_set_opmode" as workround

I tried light sleep with SDK 1.5.4.1 and SDK 2.0.0 with both "wifi_set_opmode" and "wifi_set_opmode_current" and I get the error "fpm 758".

New bug maybe?

EDIT: Just out of curiosity what are the relevance of the numbers in "fpm 758"?
