Featuresl Strong ability of diffraction: 230M features in low frequency, long wave length and strong ability of diffraction. It is applicablein complicated environment.l Narrow band transmission: Narrow band features high density, long transmitting distance and strong anti-interference ability.At same transmitting power, the transmitting distance is much longer than that of others.l Ultra-low power consumption: It supports WOR, which suits for battery power supply. In power-saving mode (Mode 2), theoverall power consumption can be regulated by setting receiving response delay and its maximum is 2000ms. The average currentis about 30uA.l Fixed transmission: Module can communicate with other modules which work in different channels and addresses. It makesnetworking and repeater easy. For example: module A transmits AA BB CC to module B (address: 0x00 01, channel: 0x80). The HEXformat is 00 01 80 AA BB CC (00 01 refers to the address of module B, and 80 refers to the channel of module B). Then module Breceives AA BB CC (only module B).l Broadcast transmission: When the module address is set as 0xFFFF, the module can communicate with other modules in thesame channel.l FEC: Forward Error Correction has high coding efficiency & good correction performance. In case of sudden interference, it cancorrect the interfered data packets proactively, so that the reliability & transmission range are improved correspondingly. WithoutFEC, those data packets can only be dropped.l Sleep mode: When the module works in sleep mode (Mode 3), it is available for configuration, but not for transmitting & receiving.The typical current is 2.0uA in this mode. It can still receive the configuration from the MCU.l Application: 230M is electricity frequency band with few interferences and strong diffraction ability. It is applicable in complicatedenvironment including working plant, factory, warehouse, office building and community.2.
