E30(915T20S)-User Manual-V1.0 Website： www.cdebyte.com/en 1. Introduction 1.1 Feature E30(915T20S) is a 100mW wireless transceiver module(UART), half-duplex& transparent transmission, which operates at 907~922.5MHz(default: 915MHz), TTL Level, compatible with the 3.3V and 5V IO port. The module has the function of data encryption & compression. The data of the module transmitted over the air features randomness. And with the rigorous encryption & decryption, data interception becomes pointless. The function of data compression can decrease the transmission time & probability of being interfered, while improving the reliability & transmission efficiency. No. Usage Description It supports WOR to reduce overall power consumption. In power-saving Ultra-low mode(Mode 2), it can regulate overall power consumption by setting receiving 1 power response delay; The maximum receiving response delay can be configured as consumption 2000ms， and the average current is about 30uA. Module can communicate with other modules which work in different channels and addresses, it is easy for networking and repeater. Fixed For example: module A transmits AA BB CC to module B (address: 0x00 01, 2 transmission channel: 0x80), HEX format is 00 01 80 AA BB CC (00 01 refers to the address of module B, 80 refers to the channel of module B), then module B receives AA BB CC (only module B). Broadcast Set the module address as 0xFFFF, then the module can communicate with other 3 transmission modules in same channel. Forward Error Correction, high coding efficiency & good correction performance. 4 FEC In the case of sudden interference, it can correct the interfered data packets proactively, so that the reliability & transmission range are improved correspondingly. Without FEC, those data packets can only be dropped. When the module works in sleep mode (mode 3), transmitting & receiving is not 5 Sleep mode available, while the configuration is available. The typical current is 5.0uA in this mode. With better capability of penetration and diffraction than 2.4G, E30(915T20S) is 6 Application suitable for the open environment with few obstacles. 1.2 Electrical Parameters No. Parameter item Parameter details Description 1 Size 17 * 30mm - 2 Weight 2.3g Average weight 3 Frequency Band 907~922.5MHz Default: 915MHz, channel:16 4 Process Lead-free, SMT To ensure the consistency and reliability 5 Connector 11PIN-2.0mm SMD 6 Supply voltage 2.1 ~ 5.5V DC Note: the voltage higher than 5.5V is forbidden Page 2 of 8 Technical Support : support@cdebyte.com

UART functional description (default) 2.1 Fixed transmission Hex Description The format: Hexadecimal, such as：00 03 04 AA BB CC 00 03 is the address of receiving module；04 is the channel ；AA BB CC is the transmission data。 Transmitting module A Hexadecimal Address：00 01；Channel 02 Receiving module B Hexadecimal Address：00 03；Channel 04 Receiving module C Hexadecimal Address：00 05；Channel 04 Receiving module D Hexadecimal Address：00 07；Channel 06 Module A must be in fixed mode. Module A Transmitting data Hexadecimal 00 03 04 AA BB CC Module B receiving data Hexadecimal AA BB CC Module C receiving data Hexadecimal No Module D receiving data Hexadecimal No Only the modules with matched address and channel can receive the data. In fixed transmission, modules only support 1 packet length (pls refer to electrical parameters). If the data packets exceed, then it need to be subcontracted automatically. 2.2 Broadcast transmission Hex Description The format: Hexadecimal, such as：FF FF 04 AA BB CC FF FF is the address；04 is the channel of receiving module；AA BB CC is the transmission data。 Transmitting module A Hexadecimal Address：00 01；Channel : 02 Receiving module B Hexadecimal Address：00 03；Channel 04 Receiving module C Hexadecimal Address：00 05；Channel 04 Receiving module D Hexadecimal Address：00 07；Channel 06 Module A must be in fixed mode.

In fixed transmission, modules only support 1 packet length (pls refer to electrical parameters). If the data packets exceed, then it need to be subcontracted automatically. 2.3 Broadcast address 1. For example, set the address of module A as 0xFF FF, and the channel as 0x04. 2. When module A works as the transmitter (transparent transmission), all the receiving module with the channel 0x04 can receive the data, so as to realize the broadcast. 2.4 Monitoring address 1. For example, set the address of module A as 0xFF FF, and the channel as 0x04. 2.When module A works as the receiver, all the receiving module with the channel 0x04 can receive the Page 4 of 8 Technical Support : support@cdebyte.com

E30(915T20S)-User Manual-V1.0 Website： www.cdebyte.com/en 3.2 Connect to MCU No. Description ( STM8L MCU ) 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. 3.3 Reset No. Description When the module is powered, AUX outputs low level immediately, conducts hardware self-check and sets the operating mode on the basis of the user parameters. During the process, the AUX 1 keeps low level. After the process completed, the AUX outputs high level and starts to work as per the operating mode combined by M1 and M0. Therefore, the user needs to wait the AUX rising edge as the starting point of module’s normal work. 3.4 AUX description AUX Pin can be used as indication for wireless send & receive buffer and self-check. It can indicate whether there are data that are yet to send via wireless way, or whether all wireless data has been sent through UART, or whether the module is still in the process of self-check initialization. No. Description 【Indication of UART output】can be used to wake up external MCU. 1 Page 6 of 8 Technical Support : support@cdebyte.com

E30(915T20S)-User Manual-V1.0 Website： www.cdebyte.com/en 【Indication of wireless transmitting】 Buffer (empty): the internal 512 bytes data in the buffer are written to the RFIC (Auto subpackage). 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. If the user starts to transmit data at this circumstance, it may cause overtime when the module is waiting for the user data, or transmitting wireless subpackage. Notes: When AUX = 1, it does not mean that all the UART data of the module have been transmitted already, perhaps the last packet of data is still in transmission. 2 【Configuration procedure of module】 Only happened when power-on resetting or exiting sleep mode. 3 No. Notes for AUX For function 1 & function 2 mentioned above, the priority should be given to the one with low 1 level output, which 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. When AUX outputs low level, it means the module is busy & cannot conduct operating mode 2 checking. Within 1ms since AUX outputs high level, the mode switch will be completed. After switching to new operating mode, it won’t be work in the new mode immediately until AUX 3 rising edge 2ms later. If AUX is on the high level, the operating mode switch can be effected immediately. When the user switches to other operating modes from mode 3 (sleep mode) or it’s still in reset 4 process, the module will reset user parameters, during which AUX outputs low level.
