Sagar Bijwe 1df85e0039 nvs_flash: Version compatibility check for nvs storage
This change adds a check for compatibility between the nvs version
found on nvs flash and the one assumed by running code during nvs
initialization. Any mismatch is reported to the user using new error
code ESP_ERR_NVS_NEW_VERSION_FOUND.

ESP-IDF A2DP-SOURCE demo

Demo of A2DP audio source role

This is the demo for user to use ESP_APIs to use Advanced Audio Distribution Profile in transmitting audio stream

Options choose step: 1. make menuconfig. 2. enter menuconfig "Component config", choose "Bluetooth" 3. enter menu Bluetooth, choose "Bluedroid Enable" 4. enter menu Bluedroid Enable, choose "Classic Bluetooth" 5. select "A2DP" and choose "SOURCE"

In this example, the bluetooth device implements A2DP source. The A2DP sink device to be connected to can be set up with the example "A2DP sink" in another folder in ESP-IDF example directory. For the first step, the device performs device discovery to find a target device(A2DP sink) named "ESP_SPEAKER". Then it initiate connection with the target device. After connection is established, the device then start media transmission. The raw PCM media stream to be encoded and transmited in this example is random sequence therefore continuous noise can be heard if the stream is decoded and played on the sink side. After a period of time, media stream suspend, disconnection and reconnection procedure will be performed.
