Chengdu Ebyte Electronic Technology Co,;Ltd E 90-DTU (230N33) user manualCopyright ©2012–2019,Chengdu Ebyte Electronic Technology Co,;Ltd 115.6. Transceiver Length and Sub-packing ModeModel Buffer Sub-packageE90-DTU (230N33) 512 bytes Automatic subcontracting of 186 bytes to send★ Note:1. If the data received by the station in a single time is larger than the capacity of a single packet, the excess datawill be automatically allocated to the second transmission until the completion of transmission.2. The data transceiver cannot receive data which is more than the buffer capacity;6. Operating ModeE90-DTU (230N33) has four operating modes, if low power consumption is not required, normal communication is recommended toconfigure the data transceiver for the normal mode (mode 0);The factory default is normal mode (mode 0).Categories M1 M0 DescriptionM ode 0 Normal M ode ON ON Open UART and RF,transparent transmission is onM ode 1 Wake-up M ode ON OFF Air wake-up mode, the packet comes with a wake-up code,M ode 2 Power-saving M ode OFF ON The air wake-up receive mode, saving receive power, the modecannot be transmittedM ode 3 Sleep M ode OFF OFF Parameter setting using the configuration software★ 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.
