BLE5 extended scan example for esp32 C3 and S3
|
||
|
|
with this code it is simple to scan legacy (BLE4) compatible advertising,
|
||
|
|
and BLE5 extended advertising. New coded added in BLEScan is not changing old behavior,
|
||
|
|
which can be used with old esp32, but is adding functionality to use on C3/S3.
|
||
|
|
With this new API advertised device wont be stored in API, it is now user responsibility
