Re: Bluetooth example to send fixed frame from dveice to mobile app over Bluetooth

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 ...

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...
