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 the 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 Programming
• The core of this module is CC2630, the user can operate according to the CC2630 chip manual (see CC2630 manual for details).
• Note the chip used by the module DC/DC.

FAQ

6.1 Communication range is too short

• The communication distance will be affected when an obstacle exists:
• Data loss rate will be affected by temperature. humidity and co-channel interference:
• The ground will absorb and reflect wireless radio waves, so the performance will be poor when testing near the ground:
• Seawater has a great ability in absorbing wireless radio waves. so performance will be poor when testing near the sea:
• The signal will be affected when the antenna is near a metal object or put in a metal case:
• The power register was set incorrectly. the 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 the recommended value. the lower the transmitting power.
• Due to antenna quality or poet matching between antenna and module.

6.2 Module is easy to damage

• Please check the power supply source, ensure that it is within the recommended supply voltage, a voltage higher than the maximum value, will permanently damage the module:
• Please check the stability of the power source, the voltage cannot fluctuate too much:
• Please make sure antistatic measures are taken when installing and using. high-frequency devices have electrostatic
• susceptibility:
• Please ensure the humidity is within a limited range. some parts are sensitive to humidity;
• Please avoid using modules under the too high or too low texture.

6.3 BER(Bit Error Rate) is high

• There is co-channel signal interference nearby. please be away from interference sources or modify frequency and channel to avoid interference:
• The 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.
