Answers checklist.

[X] I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
[X] I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
[X] I have searched the issue tracker for a similar issue and not found a similar issue.

IDF version.

v5.0 7f5ecbe

Operating System used.

Windows

How did you build your project?

VS Code IDE

If you are using Windows, please specify command line type.

None

Development Kit.

ESP32s3 wroom 1 devkit

Power Supply used.

USB

What is the expected behavior?

in state connected by ble5.0, st7789 lcd remains turned off.

What is the actual behavior?

in state connected by ble5.0, st7789 lcd repeat turn on and turn off.

if i change connection interval, repeat cycle of onoff was changed.

the below video show when connection interval is 500ms. https://user-images.githubusercontent.com/82933946/210317688-ec8c64f7-82db-4036-a15f-87244e0df73a.mp4

the below video show when connection interval is 100ms. https://user-images.githubusercontent.com/82933946/210318034-95402d35-cacc-4f5e-9063-18e3167a3ef5.mp4

if it not connected ble, lcd completly turn off.

Steps to reproduce.

Step in ble50_security_server project, set bluetooth modem sleep and add this code at gatts_profile_event_handler()

case ESP_GATTS_CONNECT_EVT:
            ESP_LOGI(GATTS_TABLE_TAG, "ESP_GATTS_CONNECT_EVT");
            /* start security connect with peer device when receive the connect event sent by the master */
            esp_ble_set_encryption(param->connect.remote_bda, ESP_BLE_SEC_ENCRYPT_MITM);

            memcpy(conn_params.bda, param->connect.remote_bda, sizeof(esp_bd_addr_t));
            conn_params.latency = 0;
            conn_params.max_int = 0x50;   
            conn_params.min_int = 0x50;    
            conn_params.timeout = 400;    

            esp_ble_gap_update_conn_params(&conn_params);

            break;

Step connect st7789 lcd by spi connection. and add this code at app_main()

#define LCD_PIN_NUM_BK_LIGHT    7
...
ESP_ERROR_CHECK(esp_lcd_panel_disp_on_off(panel_handle, false)); 
 gpio_set_level(LCD_PIN_NUM_BK_LIGHT, false);

Step try to connect to a phone

More Information.

gpio7 of esp32s3 was connected backlight pin(BLK) like below image

i can't find solution to solve this issue in the document and esp32 forum, git.

is there keyword to find solution?

suda-morris commented 1 year ago

Maybe you need to attach an oscilloscope to the GPIO7 to see what happens on that GPIO. Is it possible that the power supply is not sufficient?

hyu7000 commented 1 year ago

@suda-morris when i use oscilloscope, this image was shown

Interval is 100ms

20230103_172913

then if i disconnect ble, graph indicated 0V.

i don't know why it's 3.3v if it's connected ble.

I think power is sufficient. It shows the same symptoms when i use power supply or usb.

when i use esp32-arduino, though it connected, lcd did not blink.

suda-morris commented 1 year ago

what's the log output? is your program crashed somehow? are you sure GPIO7 is not used by other purpose in your program?

hyu7000 commented 1 year ago

@suda-morris there is no shut down and crash ,disconnection, other config of GPIO7.

though it blink st7789 lcd, BLE work well .the issus is st7789 lcd

and if i except for code related to BLE and upload, display work well without blink.

when i add this code, st7789 LCD no longer blink.

gpio_sleep_sel_dis(LCD_PIN_NUM_BK_LIGHT);

but i don't know what role _SLPSEL play.

I'm not sure if it's okay to use this function.

hyu7000 commented 1 year ago

when i add gpio_sleep_sel_dis(LCD_PIN_NUM_BK_LIGHT); and gpio_sleep_sel_en(LCD_PIN_NUM_BK_LIGHT);, it work well.

but, current cumsumption is increasing. ( about 10mA -> about 30mA )

suda-morris commented 1 year ago

Okay, now I see it's expected behavior because you enabled the CONFIG_PM_SLP_DISABLE_GPIO option, which will isolate your LCD backlight GPIO in the esp_sleep_config_gpio_isolate function. If you call gpio_sleep_sel_dis for that GPIO, esp_sleep_config_gpio_isolate will have no effect on that GPIO.

hyu7000 commented 1 year ago

if gpio_sleep_sel_dis(); is enable, power comsumption is higher than i expect.

so i tested to reduce current consumption without gpio_sleep_sel_dis();

i found that when connection interval is in 10~35ms, it is work well without gpio_sleep_sel_dis();

at this time, there is no blink.

but when connection interval is over than 40ms, it blink again.

and i want to increase interval to reduce power consumption.

@hyu7000 Does this issue still exist in the latest IDF version?
