5.5 Low power
Entering the sleep mode (refer to 4.3.1.20-4.3.1.21) requires configuration parameter instructions. It can be
awakened by setting the 24 pin low, or it can be awakened by sending any data through the serial port (wake data will be
discarded).

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.

Seawater 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).

When the power supply at room temperature is lower than the recommended low voltage, the lower the voltage is,
the lower the transmitting power is.
6.2 Module is easy to damage

Please check the power supply and ensure it is within the recommended range. Voltage higher than the peak will
lead to a permanent damage to the module.

Please check the stability of power supply and ensure the voltage not to fluctuate too much.

Please make sure anti-static measures are taken when installing and using, high frequency devices have electrostatic
susceptibility.

Please ensure the humidity is within limited range for some parts are sensitive to humidity.

Please avoid using modules under too high or too low temperature.
6.3 Bit error rate is too high

When there are co-channel signal interference nearby, be away from interference sources or modify frequency and
channel to avoid interference;

The clock waveform on the SPI is not standard. Check whether there is interference on the SPI line. The SPI bus
should not be too long.

Unfavorable power supply may cause messy code. Make sure that the power supply is reliable.
