Network formation and joining
Binding and reporting configuration
OTA upgrade support
Green Power device support

Thread

OpenThread configuration
Network dataset management
Commissioner and joiner roles
Border router setup
SRP (Service Registration Protocol)
DNS-SD integration

Matter

Matter device implementation
Device type configuration
Cluster implementation

Protocol Comparison

Protocol	Range	Data Rate	Power	Mesh
LoRaWAN	15km	0.3-50 kbps	Low	No
Zigbee	100m	250 kbps	Low	Yes
Thread	100m	250 kbps	Low	Yes
Matter	100m	Varies	Low	Via Thread

Configuration Examples

LoRaWAN OTAA

static uint8_t DevEui[] = { 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 };
static uint8_t AppEui[] = { 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 };
static uint8_t AppKey[] = { 0x00, ..., 0x00 };  // 16 bytes

MibRequestConfirm_t mibReq;
mibReq.Type = MIB_DEV_EUI;
mibReq.Param.DevEui = DevEui;
LoRaMacMibSetRequestConfirm(&mibReq);

Thread Network Configuration

otOperationalDataset dataset;
otDatasetCreateNewNetwork(instance, &dataset);
dataset.mChannel = 15;
dataset.mPanId = 0x1234;
otDatasetSetActive(instance, &dataset);

Matter Device Type

const EmberAfCluster clusters[] = {
    OnOff::Id,
    LevelControl::Id,
    Descriptor::Id,
    Identify::Id
};
