Question: After getting our boards, many friends want to know whether ST's Mesh supports low-power nodes. If so, they want to know how to modify the test.

ST engineer's answer: Our Mesh supports low-power nodes. You can verify it by following the steps below.

0. Test Preparation

a. Two ST official development boards are recommended, steval-idb008v2

b. ST BLE MESH app (Android or IOS)

1. In mesh_cfg_h, it is a low power consumption feature. Other features need to be commented out here to reflect its low power consumption feature, and then compile and burn it.

2. After the low-power node joins the network, its operation must rely on a friend node, so a friend node demonstration must be added.

It is recommended to turn on these three features

#define ENABLE_RELAY_FEATURE

#define ENABLE_PROXY_FEATURE

#define ENABLE_FRIEND_FEATURE

3. Use the mobile app ST BLE Mesh to configure the friend node and low power node. It is recommended to configure the friend node first.

4. After waiting for a while, about 40 seconds, they can communicate with each other. The low-power node actually uses the proxy feature to configure the network. This feature will be automatically removed after the network configuration. In order to ensure that the entire time is sufficient, we waited for 40 seconds here. After the low-power node enters the network, it can immediately send data to the friend node. If the friend node sends data to the low-power node, it must wait until the low-power node removes the proxy feature and establishes a friend relationship with the friend node (that is, 40 seconds) before it can send information to the low-power node.
