ESP-IDF BT-SPP-VFS-ACCEPTOR demo
======================
Demo of SPP acceptor role
This is the demo for user to use ESP_APIs to create a SPP acceptor.
Options choose step:
1. make menuconfig.
2. enter menuconfig "Component config", choose "Bluetooth"
3. enter menu Bluetooth, choose "Classic Bluetooth" and "SPP Profile"
4. choose your options.
After the program started, bt_spp_vfs_initator will connect it and send data.

ESP-IDF BT-SPP-VFS-INITATOR demo
======================
Demo of SPP initator role
This is the demo for user to use ESP_APIs to create a SPP initator.
Options choose step:
1. make menuconfig.
2. enter menuconfig "Component config", choose "Bluetooth"
3. enter menu Bluetooth, choose "Classic Bluetooth" and "SPP Profile"
4. choose your options.
After the program started, It will connect to bt_spp_vfs_acceptor and send data.
