# Directed Forwarding
|
||
|
|
|
||
|
|
(See the README.md file in the upper level 'examples' directory for more information about examples.)
|
||
|
|
|
||
|
|
This example is primarily intended to demonstrate the newly added directed forwarding feature in Mesh Protocol v1.1.
|
||
|
|
|
||
|
|
## How to use example
|
||
|
|
|
||
|
|
Please refer to this [tutorial](examples/bluetooth/esp_ble_mesh/directed_forwarding/tutorial/BLE_Mesh_Directed_Forwarding_Example_Walkthrough.md) for detailed instructions on how to run it.
|
||
|
|
|

|
|
### Hardware Required
|
||
|
|
You need prepare at least two ESP series development boards. We recommend using the [ESP32-C3-DevKitM-1](https://docs.espressif.com/projects/esp-idf/en/latest/esp32c3/hw-reference/esp32c3/user-guide-devkitm-1.html) or [ESP32-C6-DevKitC-1](https://docs.espressif.com/projects/espressif-esp-dev-kits/en/latest/esp32c6/esp32-c6-devkitc-1/user_guide.html#). Alternatively, you can use other development boards, but ensure that each board has at least one LED and one button for operation.
|
||
|
|
### Configure the project
|
||
|
|
|
||
|
|
```
|
||
|
|
idf.py menuconfig
|
||
|
|
```
|
||
|
|
|
||
|
|
### Build and Flash
|
||
|
|
|
||
|
|
Build the project and flash it to the board, then run monitor tool to view serial output:
|
||
|
|
|
||
|
|
```
|
||
|
|
idf.py -p PORT flash monitor
|
||
|
|
```
|
||
|
|
|
||
|
|
(Replace PORT with the name of the serial port to use.)
|
||
|
|
|
||
|
|
(To exit the serial monitor, type ``Ctrl-]``.)
|
||
|
|
|
||
|
|
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
|
||
|
|
|
||
|
|
## Example Output
|
||
|
|
After all devices have joined the network, you need to press the button on the provisioner(the device which runs df_client) to complete the final setup. Once the setup is complete, provisioner will provide the following output:
|
||
|
|
|
||
|
|
```
|
||
|
|
You could click to send message by directed forwarding
|
||
|
|
After the message handled, you could click again to send message by flooding
|
||
|
|
```
|
||
|
|
After seeing the above output, you can press the button again to send a network message. When the message is sent in directed forwarding, the following output will be displayed:
|
||
|
|
```
|
||
|
|
Will send a message to node(`node unicast`) with DF
|
||
|
|
```
|
||
|
|
When the message is sent in a flooding, the following output will be displayed:
|
||
|
|
```
|
||
|
|
Will send a message to node(`node unicast`) with Flooding
|
||
|
|
```
|
||
|
|
## Troubleshooting
|
||
|
|
|
||
|
|
See common troubleshooting for Directed Forwarding examples from [ESP-BLE-MESH FAQ](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/esp-ble-mesh/ble-mesh-index.html#esp-ble-mesh-faq).
