When the receiving data is more than a single packet capacity (100 bytes), the beyond part will be automaticallyassigned to the second transmission until it is completed;2. The data transceiver can not receive data which is more than the buffer capacity;3. If one can not determine the amount of data sent and received, it is recommended to use C series.5.Operating modeE90-DTU has four operating modes, if low power consumption is not required, normal communication isrecommended to configure the data transceiver for the normal mode (mode 0);The factory default is normal mode (mode 0).5.1.L series and N seriesCategories M1 M0 DescriptionMode 0 Normal Mode ON ON Open UART and RF,transparent transmission is onMode 1 Wake-up Mode ON OFF Air wake-up mode, the packet comes with awake-up code,Mode 2 Power-saving Mode OFF ON The air wake-up receive mode, saving receivepower, the mode can not be transmittedMode 3 Sleep Mode OFF OFF Parameter setting using the configurationsoftware★ Note: no need to care about the wake-up mode (mode 1) and power saving mode (mode 2) if it doesn’t request lowpower consumption.
