Pro-Lite, Inc. E32-A user manual 1. Overview 1.1 Introduction E32-A is a wireless serial port module (UART) based on SEMTECH's LLCC68 RF chip. It has multiple transmission modes, working in the 432MHz~435MHz, (default 433MHz), LoRa spread spectrum technology, LLCC68 features LoRa™, which will bring longer communication distance, and has the advantages of concentrated power density, meanwhile it has a very strong confidentiality.

Pro-Lite, Inc. E32-A user manual 5 Function description 5.1 Fixed transmission 5.2 Broadcasting transmission 5.
Pro-Lite, Inc. E32-A user manual purpose of broadcast is realized. 5.4 Monitor address For example: Set the address of module A as 0xFFFF, and the channel as 0x04; When module A is the receiver, it can receive the data sent from all modules under channel 0x04, the purpose of monitor is realized. 5.5 Reset When the module is powered, AUX outputs low level immediately, conducts hardware self-check and sets the operating mode based on user’s parameters.
Pro-Lite, Inc. E32-A user manual transmitting wireless sub package. 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. 5.6.3 Configuration procedure of module Only happened when power-on resetting or exiting sleep mode 5.6.4 Notes for AUX No.
Pro-Lite, Inc.
Pro-Lite, Inc. E32-A user manual same time the work load and power consumption of the whole system have been reduced and the efficiency of whole system is largely improved. 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.
Pro-Lite, Inc. Receiving E32-A 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.

For example, C0 00 00 1A 17 44. C1+C1+C1 7.3 Reading version number Instruction format Description In sleep mode（M0=1，M1=1）,User gives the module instruction (HEX format): C3 C3 C3,Module returns its present version number, for example C3 32 xx yy.

Pro-Lite, Inc. E32-A user manual parts with large electromagnetic interference.； High-frequency digital routing, high-frequency analog routing, and power routing must be avoided under the module.
Pro-Lite, Inc. E32-A user manual 9.2 Module is easy to damage Please check the power supply source, ensure it is 2.0V~3.6V, voltage higher than 3.6V will damage the module. Please check the stability of power source, the voltage cannot fluctuate too much. Please make sure antistatic measure are taken when installing and using, high frequency devices have electrostatic susceptibility. Please ensure the humidity is within limited range, some parts are sensitive to humidity.
