problem solved after checking all the connection to esp32c3.

Hi, using esp32(server-side) and esp32c3(client-side). 2 push buttons @ client-side to control 2 LED @ server-side for (left and right signal). Try doing 1 push button to 1 LED , it works. but now with added set of button and LED, it doesn't blink when pressed. both code compile ok. Can't figure out...

Noted. Thanks

Thanks for the link.

Not use nimBLE library before, would go thru your code to understand and learn something from it.

Saw the youtube too , should be useful for me

Thanks.

I was thinking of using BLE, if i should be (button click)sending character from server side then client side to ON LED. or the other way.

I've use handphone app to ON the LED easily but would like to explore on how to use between 2 esp32 and learnt the basic.

Hi All, i'm trying to click a button(write) @ server-side, and ON an LED on client-side upon connected. server-side, if (deviceConnected) { if (Button == 0) { // button pressed pCharacteristic->setValue("ON"); pCharacteristic->notify(); } } how do i retrieve the sent value? is there any example sket...

ok, thanks for the info.

search thru https://docs.espressif.com/projects/esp-idf/en/latest/esp32c3/api-reference/peripherals/rmt.html?highlight=rmt for this macro CONFIG_BLINK_LED_RMT_CHANNEL (from esp-idf example, blink_example_main.c) From header file it points to RMT peripheral channel number. So what is the number and w...

Hi, https://github.com/espressif/esp-idf/blob/master/examples/bluetooth/bluedroid/ble_50/multi-adv/main/multi_adv_demo.c I was going thru the above code, it will not display the all advertisements except legacy type - handphone will not display all multi advertisement when connected - below is the s...
