There are 2 names, one in the advertisement and the other in the device name characteristic. If you just want to change the advertised name you should use pAdvertising->setName("new name");

If you are meaning to change the advertised name you can only do that while advertising is stopped. That name change you are using here will change the device name characteristic value only in this case.

@h2zero Thanks! It works!
I encountered another problem. Is the DeviceName only allowed to be changed once?

#include <NimBLEDevice.h>

#include <NimBLEAdvertisedDevice.h>

static NimBLEAdvertising *pAdvertising = nullptr;
static uint32_t count = 0;
BLEUUID serviceUUID("12345678-0003-4538-BCD7-7ECFB51297C1");
void setup() {
Serial.begin(115200);
Serial.println("Starting BLE work!");
NimBLEDevice::init("test1");
pAdvertising = NimBLEDevice::getAdvertising();
pAdvertising->addServiceUUID(serviceUUID);
}
void loop() {
pAdvertising->stop();
count++;
char test[100] = "name";
char buffer[50];
sprintf(buffer, "%u", count);
strcat(test, buffer);
Serial.printf(test);
NimBLEDevice::setDeviceName(test);
pAdvertising->start();
delay(3000);
// setDeviceName allowing for changing the device name while the BLE stack is active.: https://github.com/h2zero/NimBLE-Arduino/blob/bc333ccb6e8d9ff2059af9cbd5006a290a4de3a5/CHANGELOG.md?plain=1#L17
}
The DeviceName is always "name1" (observe via NRF Connect).

It works for me, thanks a lot!
