Chapter 1 Product Overview
1.1 Brief introduction
MBL series evaluation kits are designed to help users quickly evaluate Ebyte's new generation of package-compatible wireless
modules. Most of the pins on the board have been led out to pin headers on both sides, and developers can easily connect various
peripheral devices through jumpers according to actual needs.
The kit provides complete software application examples to help customers quickly get started with wireless data communication
development. According to customer needs, different types of Sub-1G wireless modules can be mounted on the board. Supported
modules are available in pin-compatible packages for quick replacement.

workspace
The global macro definition and file path are defined in the C/C++ Compiler option, which
are used to distinguish the driver files of different modules. When switching workspaces,
different macro definitions will be used to switch driver files of different modules
“Exclude from build” attribute of Drivers/Ebyte/RF has changed, that is, select the target
module driver folder to participate in the compilation process. Changed the Additional
include in the project C/C++ Compiler, that is, specifying the module driver file path.
Changed the Defined symbols in the project C/C++ Compiler, that is, defined the global
macro definition to help configure the module driver properties.

2. 3 main function
The main function entry is in main.c. The demo function process is simplified as follows:
Matter
Explanation
1
Key Function
If a button is pressed, the command data is sent wirelessly. Essentially sending a
specific string "ping" and expecting a response "pong"
2
Serial data to wireless
transmission
After the serial port receives the data, it automatically starts wireless transparent
transmission of data. Of course, it contains some special command responses, which
are mainly used for special tests and can be ignored by users. After the sending is
completed, the user function will be automatically called back to process the sending
logic by itself.
3
Receive data wirelessly
Generally, the internal status flag of the module is read to determine whether there is
data, and the underlying driver will copy the data and pass it to the user's callback
function, so as to process the receiving logic by itself
The software process is simplified as shown in the figure below:
2. 4 Transceiver timing
The wireless module has multiple operating states, and specific functions can only be completed in the
corresponding states. From the simplest sending and receiving data, only the sending mode and receiving mode are
considered.
Matter
Explanation
1
Receive mode
After the default initialization is completed, it automatically enters the receiving mode.
In essence, the receiving function is called in the initialization to enter the receiving
mode. If you need to consider entering other modes after initialization, such as sleep,
you can directly replace it with the same type of function Go_xxxxx().
2
Send mode
When calling the send function, the underlying driver actually switches the module
into standby mode first, and usually completes the modulation parameter configuration

in this mode, such as frequency, power, frequency offset, etc. After the parameters are
configured correctly, gradually enter some intermediate modes, open the internal
FIFO, PA, external XTAL, etc., and the current consumption will gradually increase.
Eventually switch into send mode, triggering wireless data transmission. After
completion, the module enters the standby mode. In this state, sending and receiving
cannot continue, and the user needs to handle the next step in the callback function.
When the function is complex, continuous reception or continuous transmission is
required, please further switch to other modes according to the characteristics of the
chip.
The timing diagram is as follows:
