about central

hi,

I have button service program in peripheral side, it is updating the button state value in server and I want read the value from peripheral to central and actuate the led in central device, i am following mbed os-led _blinker an example,

I just modified little in given code

void triggerToggledWrite(const GattReadCallbackParams *response) {
    if (response->handle == ledCharacteristic.getValueHandle()) {
        printf("triggerToggledWrite: handle %u, offset %u, len %u\r\n", response->handle, response->offset, response->len);
        for (unsigned index = 0; index < response->len; index++) {
            printf("%c[%02x]", response->data[index], response->data[index]);
        }
        printf("\r\n");

        /*uint8_t toggledValue = response->data[0] ^ 0x1;
        ledCharacteristic.write(1, &toggledValue);*/
        
       actuatedLED = response->data[0];
        
    }
}

but its not working any other modification is required please suggest me.

Can you define "its not working" ? Do you see the function being invoked? What is printed?
