I'm developing a firmware using ESP32 and Arduino Framework. I'm using BLE with the "official" library, this device will be connected to a smartphone. There is a peculiarity,
I already done everything but there is a problem
I add a new Service RUNTIME... on Android I managed to be able to refresh the services list correctly... but on iOS it does not work... so doing my research I found out that seems that I have to send an Indication on the Service Changed characteristic (0x2A05) inside the Generic Attribute Service (0x1801) to inform the smartphone that the GATT structure has changed, so it have to get new structure from the esp32 instead of the cache (?).
The question are
What is the right way to inform the smartphone through the Service Changed characteristic? This should be automatically done by the BLE library?
