Component implementation for Bluetooth SIG Mesh SDK of Telink.

For RN >= 0.60 and Android SDK >= 31 , must

npm i --save react-native-btsig-telink

For RN >= 0.60 and Android SDK >= 29 but < 31 , also can

npm i --save react-native-btsig-telink@2.x

For RN >= 0.60 and Android SDK < 29 , must

npm i --save react-native-btsig-telink@1.2.x

For RN < 0.60 , must

npm i --save react-native-btsig-telink@1.0.x

For RN < 0.60, need files edited below:

In android/app/build.gradle

dependencies {
    implementation project(':react-native-btsig-telink')
}

In android/app/src/main/java/com/YourProject/MainApplication.java

import com.telink.sig.mesh.TelinkBtSigPackage;
...
    new TelinkBtSigPackage(),

In android/settings.gradle

include ':react-native-btsig-telink'
project(':react-native-btsig-telink').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-btsig-telink/android')

cd ios
pod install

For RN < 0.60, add below in ios/Podfile before pod install

  pod 'RNBtSigTelink', :path => '../node_modules/react-native-btsig-telink'

import meshModule from 'react-native-btsig-telink';

export default class MeshModuleExample extends React.Component {
    constructor(props) {
        super(props);
        meshModule.passthroughMode = {
            silan: [

        meshModule.addListener('leScan', this.onLeScan);
        meshModule.netKey = YOUR_16_BYTES_NETKEY;

        // you can save data comes from (provision then bind function) meshModule.configNode()
        // Promise into devicesSavedInRedux after onLeScan() , then `meshModule.devices = devicesSavedInRedux`
        // here befor meshModule.doInit() so that can auto connect them after APP restart.
        // // devicesSavedInRedux = [{
        // //     meshAddress: 1,

        // meshModule.devices = devicesSavedInRedux;

        // if you want 8KB/s not 42B/s
        //
        // also need change firmware:
        //     set EXTENDED_ADV_ENABLE to 1 in `vendor/common/mesh_config.h`
        //     (maybe) let is_not_use_extend_adv() return 0 in `vendor/common/mesh_node.c`
        //
        // change JS here:
        // meshModule.extendBearerMode = meshModule.EXTEND_BEARER_MODE.GATT_ADV;

        meshModule.doInit();
        meshModule.startScan({
            isSingleNode: false, // if true, will stop scan after found one device
            timeoutSeconds: 10,
        });
    }

    onLeScan = data => {
        // if you want data.productUUID here is same with your device's PID, you
        // should enable `PROVISION_FLOW_SIMPLE_EN` in your device's firmware code.
        console.warn(data);
    }

    render() {
        return (
            <View/>
        );
    }
}

Please discover more in index.native.js.

If you want fastBind, you can copy PrivateDevice.js to create your own and modify, then put PrivateDevice.filterWithPid(PID).cpsData into configNode({cpsData}), here PID comes from productUUID with startScan().

You also need enable PROVISION_FLOW_SIMPLE_EN in firmware code.

The provision + bind time of 1 device, in telink sdk 3.1.0, with fastBind is 7s and without fastBind is 20s, but in telink sdk 3.3.3.5, with or without fastBind is almost the same 7s, so the fastBind is not important now, only except that you want data.productUUID in onLeScan to be same with your device's PID then you only need enable PROVISION_FLOW_SIMPLE_EN in firmware code.

react-native-btsig-telink@1.x is based on telink sdk 3.1.0.

react-native-btsig-telink@2.x and @3.x is based on telink sdk 3.3.3.5.

react-native-btsig-telink@4.x suggest useAddressesInsteadOfGroup but default still false.

react-native-btsig-telink@5.x let useAddressesInsteadOfGroup default true.

Use PrivateDevice.js instead of PrivateDevice.java and DeviceTypeModel on iOS, ref to fastBind above.

getFirmwareVersion() is not working by default, ref to the comments of canMeshOta =.

To keep data usage after APP upgrade from react-native-btsig-telink@1.x based to react-native-btsig-telink@2.x based, data comes from (provision then bind function) configNode() still use nodeInfo, ref to NodeInfo.js which comes from react-native-btsig-telink@1.x/android/src/main/java/com/telink/sig/mesh/model/NodeInfo.java.

When device A is 3.1.0 and device B is 3.3.3.5, direct connected is device B, if APP is 3.1.0, then sendCommand({meshAddress: 0xFFFF}) can't affect (mesh to) device B, but it's OK if APP is 3.3.3.5.

Below table: despite is_not_use_extend_adv() return 0 or not; "delay_while" means user business code use while loop as precise delay; "bytes" means MeshMessage.params; "2nd device" means not direct connected device; 8KB/s and 42B/s tested by 300 bytes, no 8KB/s or 42B/s means "2 devices" not controlled.

PS: test also found, despite is_not_use_extend_adv() return 0 or not, not only not affect 8KB/s test result with 300 bytes, but also not affect OTA speed is still so high.

如下表格: 无关乎 is_not_use_extend_adv() 是否返回 0 ；"delay_while" 意为用户业务代码中用 while 死循环作为精确延时； “字节”意为 MeshMessage.params ；“第 2 个设备”意指非直连设备； 8KB/s 和 42B/s 都是使用 300 字节来测试的，如果不存在 8KB/s 或 42B/s 则表明“ 2 个设备”都不受控。

另：测试还发现，无关乎 is_not_use_extend_adv() 是否返回 0 ，除了不会影响 300 字节时测得 8KB/s ，而且也不会影响 OTA 速度仍然那么快。

To solve the problem of "2nd device delay 3s if delay_while too often", you should put

blt_sdk_main_loop();

besides your delay_while code.

Because blt_sdk_main_loop() itself also cost some time, maybe you prefer mesh_send_adv_in_connected():

mesh_send_adv_in_connected();

extern u32 adv_in_conn_tick;
extern u32 blt_advExpectTime;
void mesh_send_adv_in_connected()
{
    if (BLS_LINK_STATE_CONN == blt_state) {
        if (clock_time_exceed(adv_in_conn_tick, 10 * 1000)) {
            adv_in_conn_tick = clock_time();
            mesh_send_adv2scan_mode(1);
        }
    } else if ((u32)(clock_time() - blt_advExpectTime) < BIT(31) && !blc_tlkEvent_pending ) {
        blt_send_adv2scan_mode(1);
    }
}
