Hi,
LoRa itself is a PHY that can be used in all network topologies. Mesh networking expands the range of the network, but reduces network capacity, At the expense of synchronization overhead and battery life reduction, due to synchronization and hop count. It is necessary to extend the distance with a mesh network architecture, so LoRaWAN chooses a star architecture to optimize network capacity, battery life, and easy installation.
See lessLoRa module communication failure issue
Hi, First check whether the SPI communication is successful, the successful sign is that the version value of the read chip is 0x12, the DIO0 pin is responsible for notifying the MCU that the reception is completed and check whether the DIO0 pin configuration is normal. The configuration parametersRead more
Hi,
First check whether the SPI communication is successful, the successful sign is that the version value of the read chip is 0x12, the DIO0 pin is responsible for notifying the MCU that the reception is completed and check whether the DIO0 pin configuration is normal. The configuration parameters of LoRa should be consistent, including frequency, spreading factor, bandwidth, coding rate, preamble length, frequency hopping enable, syncword, and low-rate optimization; if one of the above parameters is different, communication cannot be performed.
See lessLoRa data rate
Hi, LoRa defines a specific set of data rates, but there are multiple options for the end chip or PHY. SX1272 supports data rates from 0.3 to 37.5kbps, SX1276 supports 0.018 to 37.5kbps.
