Trying to understand Bluetooth module components in esp-iot-solution.

[jeetrohan]

Bluetooth module has multiple components, some partially documented others not.

Moreover some of these seem overlapping; ex. ble_services/hrs and ble_profiles/std /ble_hrp. Which one should I use and why?

I'm trying to understand whether these are connected or just standalone components??

Also, some of the functionality is not so transparent ... like ble_conn_mgr... does it supports GATT too? Is it supposed to be updated to support GATT in future? or there will be a different component for that?

And to what is ble_hci? Espressif's internal bluetooth stack project?

More importantly.. if I want to implement something of my own using any of these?? What is the possible extent?
