5. Basic operation
5.1 Hardware design
It is recommended to use a DC stabilized power supply. The power supply ripple factor is as small as possible and
the module needs to be reliably grounded.
Please pay attention to the correct connection of the positive and negative poles of the power supply, reverse
connection may cause permanent damage to the module.
Please check the power supply to ensure that between the recommended supply voltage, if exceeding the maximum,
the module will be permanently damaged;
Please check the stability of the power supply. Voltage can not fluctuate greatly and frequently;
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 Layer High-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;
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.
5.2 Software writing
The core of this module is CC2652P, and users can operate according to the CC2652P chip manual.

6. FAQ
6.1 Communication range is too short
The communication distance will be affected when obstacle exists;
Data lose rate will be affected by temperature, humidity and co-channel interference;
The ground will absorb and reflect wireless radio wave, so the performance will be poor when testing near ground;
Sea water has great ability in absorbing wireless radio wave, so performance will be poor when testing near the sea;
The signal will be affected when the antenna is near metal object or put in a metal case;
Power register was set incorrectly, air data rate is set as too high (the higher the air data rate, the shorter the
distance);
The power supply low voltage under room temperature is lower than recommended value, the lower the voltage, the
lower the transmitting power;
Due to antenna quality or poor matching between antenna and module.
6.2 Module is easy to damage
Please check the power supply source, ensure it is between the recommended supply voltage, voltage higher than
the maximum 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.
Please avoid using modules under too high or too low temperature.
6.3 BER(Bit Error Rate) is high
here are co-channel signal interference nearby, please be away from interference sources or modify frequency and
channel to avoid interference;
Poor power supply may cause messy code. Make sure that the power supply is reliable;
The extension line and feeder quality are poor or too long, so the bit error rate is high.
