Any drawback if use external 32.768kHz xtal for BLE light sleep
Posted: Fri Jan 06, 2023 7:10 am
Hi, Im working on a project using ESP32s3 for a HID USB device
As the power consumption and temp of the chip is bit higher then requirement
So I use external 32.768kHz xtal for BLE light sleep followed by this guide
https://github.com/espressif/esp-idf/is ... -500312453
which work fine, the temp does drop.
But a weird situation is that some some of the samples BLE not work normally and return error state 133
I want to ask if using 32.768kHz for BLE will cause any drawback?
or anything needed to be taken extra care?
Thank you for the help!
