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
};
