When designing the power supply circuit for the module, it is often recommended to reserve more than 30% of the
margin, so the whole machine is beneficial for long-term stable operation;
The module should be as far away as possible from the power supply, transformers, high-frequency wiring and other
parts with large electromagnetic interference;
Bottom LayerHigh-frequency digital routing, high-frequency analog routing, and power routing must be avoided
under the module. If it is necessary to pass through the module, assume that the module is soldered to the Top Layer,
and the copper is spread on the Top Layer of the module contact part(well grounded), it must be close to the digital
part of the module and routed in the Bottom Layer;
Assuming the module is soldered or placed over the Top Layer, it is wrong to randomly route over the Bottom Layer
or other layers, which will affect the module's spurs and receiving sensitivity to varying degrees;
It is assumed that there are devices with large electromagnetic interference around the module that will greatly
affect the performance. It is recommended to keep them away from the module according to the strength of the
interference. If necessary, appropriate isolation and shielding can be done;
Assume that there are traces with large electromagnetic interference (high-frequency digital, high-frequency analog,
power traces) around the module that will greatly affect the performance of the module. It is recommended to stay
away from the module according to the strength of the interference.If necessary, appropriate isolation and shielding
can be done;
If the communication line uses a 5V level, a 1k-5.1k resistor must be connected in series (not recommended, there is
still a risk of damage);
Try to stay away from some physical layers such as TTL protocol at 2.4GHz , for example: USB3.0;
The mounting structure of antenna has a great influence on the performance of the module. It is necessary to ensure
that the antenna is exposed, preferably vertically upward. When the module is mounted inside the case, use a good
antenna extension cable to extend the antenna to the outside;
The antenna must not be installed inside the metal case, which will cause the transmission distance to be greatly
weakened.
4.2 Programming
The core of this module is CC2630, its driving method is completely equivalent to CC2630, the user can operate
according to the CC2630 chip manual (see CC2630 manual for details);
It is recommended to use the Code Composer Studio (CCS) Integrated Development Environment (IDE).
Code Composer Studio is an integrated development environment (IDE) that supports TI's microcontroller and
embedded processor products. Code Composer Studio includes a complete set of tools for developing and
debugging embedded applications. It includes the C/C++ compiler, source editor, project build environment,
debugger, descriptor, and many other features. The IDE provides a single user interface to help you through every
step of the application development process. Familiar tools and interfaces allow users to get started faster than ever
before. Code Composer Studio combines the benefits of the Eclipse software framework with TI's advanced
embedded debugging capabilities to provide embedded developers with a compelling, feature-rich development
environment.
★
When transmitting, set DIO_7 pin to high level and DIO_13, DIO_14 pins to low level;
★
When receiving, set DIO_7 pin to low level and DIO_13, DIO_14 pins to high level;
★
Before turning off, set DIO_7, DIO_13, DIO_14 pins to low;
The register configuration can be reinitialized when the chip is idle for greater stability.
