Page 7: Connect To Mcu
Description（STM8L MCU） The UART module is TTL level. 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 Copyright ©2012–2019，Chengdu Ebyte Electronic Technology Co., Ltd... -
Page 8: Reset
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. Copyright ©2012–2019，Chengdu Ebyte Electronic Technology Co., Ltd... -
Page 9: Configuration Procedure Of Module
AUX stays 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 process, the module will reset user parameters, during which AUX outputs low level.

Page 10: Operating Mode
Therefore, the general recommendation is to detect the output state of the AUX pin and wait for 2ms to switch after the AUX output is high. 6.2 Fixed Frequency Mode (Mode 0) Type When M1 = 0 & M0 = 0, module works in mode 0 Copyright ©2012–2019，Chengdu Ebyte Electronic Technology Co., Ltd... -
Page 11: Frequency Hopping Mode (Mode 1)
When M0 = 0，M1 = 1，module works in mode 2. Transmitting The same as that in mode 0. Receiving The same as that in mode 0. 6.5 Sleep mode (Mode 3) Type When M0 = 1，M1 = 1，module works in mode 3. Copyright ©2012–2019，Chengdu Ebyte Electronic Technology Co., Ltd... -
Page 12: Quick Communication Test
USB test board (M1 = 0，M0 = 0), make the module work in mode 0. Optional power supply, 3.3V or 5V (it supports 3.3V ~ 5.5V). Operate AccessPort software and select the correct serial port code. Copyright ©2012–2019，Chengdu Ebyte Electronic Technology Co., Ltd... -
Page 13: Instruction Format
Module returns its present version number, for example C3 34 xx yy. 32 here means the module model (E34 series); xx is the version number and yy refers to the other module features. Copyright ©2012–2019，Chengdu Ebyte Electronic Technology Co., Ltd... -

The antenna is an important role in the communication process. A good antenna can largely improve the communication system. Therefore, we recommend some antennas for wireless modules with excellent performance and reasonable price. Copyright ©2012–2019，Chengdu Ebyte Electronic Technology Co., Ltd... -
