| 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
};
