~5us ADC read using ESP32-S3

Hi,
I'm trying to do some very fast ADC sampling with at least 200kHz sampling rate.
Utilizing only ADC1, with Oneshot mode driver, I was able to obtain analog data in ~30 us. With Continuous mode driver, using very small conversion frame size, it was feasible but super unsteady; when I do some hard ...

Re: BLE Multiple Instances

Thanks for your fast reply.

This is actually the exact thing what I want, and this is the expected case when the central performs disconnection (and it works well). However, when I disconnect using esp_ble_gap_disconnect(), after starting advertising it reconnects automatically to the previously ...

If possible, how can I implement that?
