Is there has any example with the ext_advertiser?

[LuciaferKelvin]

I tested the example and used the start advertising function. However, the device cannot be discovered by iOS, while Android can detect it. I have no idea why this is happening.
Could anyone tell me the possible reason? Additionally, the hardware I am using is: Cortex-M4 + HCI + ESP32-C3.

`static void start_periodic(void)

uint8_t instance = 5;

int rc;

 console_printf("instance %u started (periodic)\n", instance);

}` using only this funciton.

Hi,

There is https://github.com/apache/mynewt-nimble/tree/master/apps/ext_advertiser which shows how to run few advertising instances with various configurations

Hello, I have tested this case and found something wrong with it, similar to the description ：
