Chengdu Ebyte Electronic Technology Co,;Ltd E32-868T30S user manual home, etc. The modules feature data encryption and compression. The data transmitted in air features randomness. air Data Rate (Default 2.4kps). The encryption-decryption algorithm makes data interception meaningless. And the data compression enables shorter transmitting time and lower rate of being interfered, which increased the reliability and transmitting efficiency.

Chengdu Ebyte Electronic Technology Co,;Ltd E32-868T30S user manual Description（STM8L MCU） No. 1 The UART module is TTL level. 2 For some MCU works at 5VDC, it may need to add 4-10K pull-up resistor for the TXD & AUX pin. 5 Function description 5.1 Fixed transmission 5.2 Broadcasting transmission Copyright ©2012–2020，Chengdu Ebyte Electronic Technology Co.,Ltd.
Chengdu Ebyte Electronic Technology Co,;Ltd E32-868T30S user manual 5.3 Broadcasting address For example: Set the address of module A as 0xFFFF or 0x0000, and the channel as 0x04; When module is the transmitter (transparent transmission), all modules under channel 0x04 will receive the data, the purpose of broadcast is realized. 5.
Chengdu Ebyte Electronic Technology Co,;Ltd E32-868T30S user manual 5.6.2 Indication of wireless transmitting Buffer (empty): the internal 512 bytes data in the buffer are written to the RFIC (Auto sub-packaging). When AUX=1, the user can input data less than 512 bytes continuously without overflow. Buffer (not empty): when AUX=0, the internal 512 bytes data in the buffer have not been written to the RFIC completely.
Chengdu Ebyte Electronic Technology Co,;Ltd E32-868T30S user manual 5.6.4 Notes for AUX No. Description For function 1 & function 2 mentioned above, the priority should be given to the one with low level output, which 1 means if it meets each of any low level output condition, AUX outputs low level, if none of the low level condition is met, AUX outputs high level. 2 3 4 When AUX outputs low level, it means the module is busy & cannot conduct operating mode checking.
Chengdu Ebyte Electronic Technology Co,;Ltd E32-868T30S user manual are any serial data that are yet to finish wireless transmitting, it will start to work in new mode after the UART transmitting finished. After the module receives the wireless data & transmits the data through serial port, it will start to work in new mode after the transmitting finished. Therefore, the mode-switch is only valid when AUX outputs 1, otherwise it will delay.
Chengdu Ebyte Electronic Technology Co,;Ltd E32-868T30S user manual 6.2 Normal mode (mode 0) When M1 = 0 & M0 = 0, module works in mode 0 Transmitting The module can receive the user data via serial port, and transmit wireless data package of 58 bytes. When the data inputted by user is up to 58 byte, the module will start wireless transmission. During which the user can input data continuously for transmission.
Chengdu Ebyte Electronic Technology Co,;Ltd E32-868T30S user manual In mode 2, it is required the data transmitter works in mode 1. The wireless module monitors the preamble code at regular time. Once it gets the preamble code, it will remain as receiving status and waiting for the completion of receiving the entire valid data package. Then the AUX outputs low level, 5ms later the serial port is open to transmit received wireless data through TXD. Finally, AUX outputs high level after process completed.
Chengdu Ebyte Electronic Technology Co,;Ltd E32-868T30S user manual 7 Command format In sleep mode（Mode 3：M1=1, M0=1）, it supports below instructions on list. (Only support 9600 and 8N1 format when setting) Instruction No. format 1 C0+working parameters 2 C1+C1+C1 3 C2+working parameters 4 C3+C3+C3 5 C4+C4+C4 Illustration C0 + 5 bytes working parameters are sent in hexadecimal format. 6 bytes in total and must be sent in succession, ( Save the parameters when power-down ).
7.4 Reset command Instruction format Description In sleep mode（M0=1，M1=1）, User gives the module instruction (HEX format): C4 C4 C4, the module resets for one time. During the reset process, the module will conduct self-check, AUX outputs low level. After reset completing, the AUX outputs high level, then the module starts to work regularly which the working mode can be switched or be given another instruction. C4+C4+C4 7.5 Parameter setting command No.
