Hello Team,
I believe using ble_adv example it can be doable like broadcasting packets to all bluetooth enabled devices.
Let me know if anyone has used ble_adv into ESP32 IDF 3.2 version.

Re: Query for 32 KHz XTAL
It is needed if you need stable (<5% drift) timekeeping in sleep modes where the 40MHz crystal is switched off (i.e. deep sleep), or if you need BT modem sleep. Hello ESP_Sprite. Thanks for your prompt response. So, Ultimately, It is used to get proper clock into mode of sleep modes. We can remove ...

Query for 32 KHz XTAL
Hello Espressif Team, Hope you are doing well and everything is going well from your end. We have one query regarding 32 KHz XTAL which is being used into many ESP32 based design and we have also used from reference design into our product. But I would like to know that what will happen if we remove...

Re: RTC accuracy
I know this is an old post, but the to person who said they wanted better accuracy without the added product expense of a separate RTC, I'd like to point out thatDS3231 RTC modules with built in coin cells sell for less than $2 (USD), which is probably less than the cost of adding a crystal to the ...

Re: ADC2 support
Hi, is the issue with ADC2 and WIFI happening with the ESP32-Mini as well? I can't find anything on the datasheet that says so. Hello, I think there is no any dependencies on Hardware as it is just matter of Stack changes into ESP32 IDF which I believe is included into Latest Stable IDF Still you c...
