5. User Guide

5.1 Notice for Hardware

It is recommended to use DC stabilized power supply. The power supply ripple factor should be as small as possible, and

the module should be reliably grounded.

Please ensure that the positive and negative poles of the power supply are properly connected. If the reverse connection is

made, the module may be permanently damaged.

Please ensure the power supply voltage is within the working voltage range. If the maximum voltage is exceeded, the

module will be permanently damaged.

Please check the stability of the power supply, and the voltage cannot be fluctuated frequently;

When designing the power supply circuit for the module, it is recommended to reserve more than 30% of the margin to

Chengdu Ebyte Electronic Technology Co.,Ltd E79-900DM2005S User Manual

achieve long-term stable operation of the system;

The installation location of the module should be as far away as possible from the power supply, transformers,

high-frequency wiring and other parts with large electromagnetic interference;

High-frequency digital routing, high-frequency analog routing, and power routing must avoid module locations. If the

wiring must pass under the module, assuming that the module is soldered to the Top Layer, the area where the module is in

contact with the Top Layer should be covered with copper (all copper is well grounded), and the area must be close to the digital

part of the module and routed in the Bottom Layer;

If the module is soldered or placed in the Top Layer, it is wrong to randomly route on the Bottom Layer or other layers,

which will affect the spurs and receiving sensitivity of the module to varying degrees;

If there is a device with large electromagnetic interference around the module, it will greatly affect the performance of the

module. It is recommended to maintain the distance from the module according to the strength of the interference. If

circumstances permit, it is recommended to do proper isolation and shielding;

If there are wirings with large electromagnetic interference around the module (such as high frequency digital, high

frequency analog, power line), the performance of the module will be greatly affected. It is recommended to do proper isolation

and shielding;

Try to keep the module away from some physical layers such as the 2.4GHz TTL protocol, for example: USB3.0;

The antenna installation structure has a great influence on the performance of the module. Make sure that the antenna is

exposed and preferably vertical. When the module is installed inside the casing, it is recommended to use a good antenna

extension cable to extend the antenna to the outside of the casing;

The antenna must not be installed inside the metal case, which will greatly reduce the transmission distance.

5.2 Programming

The core of this module is CC1352P, and the user can operate according to the CC1352P chip manual.

Recommended parameters of frequency accuracy

Adjust the parameter of SET_CCFG_MODE_CONF_XOSC_CAPARRAY_DELTA in ccfg.c file to 0xFA

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 2.5V, 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 2.0V~3.6V, voltage higher than 3.6V 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
