# BananaPi M5 / M2S

## Enabling WiFi and Bluetooth

BananaPi M5 and M2S have an optional WiFi mezzanine board with an RTL8822CS chip providing 802.11 b/g/n/ac on 2.4GHz/5GHz channels and Bluetooth 5.0 connectivity. The board is not active unless enabled through a device tree modification.

On BPI-M5 create `/storage/.config/autostart.sh` with the following content:

```shell
mount -o remount,rw /flash
fdtput -t s /flash/meson-sm1-bananapi-m5.dtb /soc/sd@ffe03000 status okay
fdtput -t s /flash/meson-sm1-bananapi-m5.dtb /soc/bus@ffd00000/serial@24000 status okay
mount -o remount,ro /flash
```

On BPI-M2S create `/storage/.config/autostart.sh` with the following content:

```sh
mount -o remount,rw /flash
fdtput -t s /flash/meson-sm1-bananapi-m2s.dtb /soc/sd@ffe03000 status okay
fdtput -t s /flash/meson-sm1-bananapi-m2s.dtb /soc/bus@ffd00000/serial@24000 status okay
mount -o remount,ro /flash
```

After rebooting the board, the WiFi and BT devices should be detected:

```bash

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://wiki.libreelec.tv/hardware/amlogic/bananapi-m5-m2s.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
