anchao opened a new pull request #1651:
URL: https://github.com/apache/incubator-nuttx/pull/1651
## Summary
The current implementation of Xiaomi’s Bluetooth stack is different with the
current architecture.
HCI transport layer communication will be based on /dev/ttyS* devices
instead of sockets,
The stack module prefers like bluedroid instead of bluez, host/l2cap will
run on userspace,
The reasons for this are as follows:
```
1. Low coupling and more flexible:
The stack implementation is completely decoupled from the
operating system,
which will completely decouple the nuttx from the stack with
different implementation characteristics,
Developers will have more ways to choose the stack which they
need (btstack/zephyr/nimble/bluedroid ?)
2. Easier to porting:
Implement and maintain the OSI layer is enough to porting the
open source stack.
3. Sustainability/low maintenance cost:
Keep in sync with the main line of the 3-party stack, regularly
updated with the common code.
(For the stack common code is not modified at all or some minor
possible modification,)
4. Code contribution:
Since the common code is exactly the same as the main line, the
stack issues will be solved in the corresponding community.
This is also the contribution of nuttx developers to other open
source projects.
```
At present, Xiaomi has completed the porting of the zephyr stack(including
ble, mesh, shell，etc),
and preparing to apply it to the internal module products,

1. Shell:

```
2. Stack:

3. OSI porting:
`https://github.com/anchao/zblue/tree/master/port`
4. HCI and Chip:
```
Realtek AmebaZ rtl8720c:
https://github.com/anchao/zblue/tree/master/port/chip/amebaz
XRadio tech:
https://github.com/anchao/zblue/tree/master/port/chip/xr829
libusb H2 for NuttX simulation(refer to sim/zblue):
https://github.com/anchao/zblue/tree/master/port/drivers/bluetooth/hci/libusb.c
```
and also we have nuttx sim demo for the zephyr stack,
If anyone is interested, you can try the following steps to run the stack on
sim:
1. USB Dongle: (Recommend CSR8510 (BT+BLE+MESH 5.0))
```
$ lsusb
...
Bus 001 Device 073: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth
Dongle (HCI mode)
...
```
2. Setup Environment:
```
sudo apt-get install libusb-1.0-0-dev:i386
sudo apt-get install libusb-1.0-0-dev
```
3. Download the source code:
```
git clone g...@github.com:apache/incubator-nuttx.git
git clone g...@github.com:apache/incubator-nuttx-apps.git
git clone g...@github.com:anchao/external.git
git clone g...@github.com:anchao/tinycrypt.git external/tinycrypt
git clone g...@github.com:anchao/zblue.git external/zblue
mv incubator-nuttx-apps apps
ln -s ../external apps/external
```

Directory structure:
```
$ tree

5. Compile sim/zblue
```
cd incubator-nuttx
./tools/configure.sh sim/zblue
make
```
6. Startup the stack:
