Hi Sir! Do you have an example of esp32 receiving and sending data to android phone via BLE? even just a 1 and 0 data sir.
Code: Select all
I (9426) GATTS: SERVICE_START_EVT, conn_id 0, remote e4:12:1d:a3:f2:2f:, is_conn 1
Ah, sorry.kolban wrote:Ahhh ... with you now. This appears not to be a question related to the C++ BLE classes that this thread is about but rather generic BLE using the underlying ESP-IDF BLE lower level APIs. I'm afraid I don't have much of anything to offer in that regard. You are most likely going to get the support with a specific thread on that more general topic.
