1.1 Introduction

is further improved. Communication stability is greatly improved compared to products without power amplifiers
and low noise amplifiers. A large number of domestic Si24R1s are used in the market to pretend to be nRF24L01P
produced by NORDIC. it is recommended that the user tests the communication stability and distance under the
real use scenario and the difference is very obvious. Industrial grade high precision 16MHz crystal is used. This
product has obtained domestic and international authoritative certification such as FCC, CE, RoHS, etc.
Since the E01-2G4M13S is a SPI RF transceiver module, you need to use the MCU driver or a dedicated SPI
debugging tool.

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
Due to antenna quality or poor matching between antenna and module.
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
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.
There are co-channel signal interference nearby, please be away from interference sources or modify
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;
