Features

• It work with Modbus protocol but not work with LoRaWAN.

• The devices to be used in a loop group for data transmission.  It is like an RS-485 in semi-duplex but wireless.  

• In the loop group just pick one LoRa device to work as a MASTER and the other LoRa devices are SLAVE.

• These devices have general LoRa features such as long range, low packet size and loose in data collecting.  

• We recommend the packet not over 100 bytes per second and the condition could accept data lost.  

• Generally it work good for environment data collection to get long trend.   It’s not suitable for instant On/Off work.

• Distance of LoRa transmission is long range subject to antenna to be Line-Of-Sight from Master to Slaves.
