Product application and secondary development precautions
1. Problems related to wireless interference:
1.1 Use the ping command to test the wireless transmission performance. If it is found that the delay of
the ping packet response is extremely uneven, and there are many responses with a large delay, it can
basically be judged that the wireless has been strongly interfered;
1.2 The product antenna should be kept as far away as possible from sources of interference, such as
switching power supplies, antennas of other modules or wireless products, etc.;
1.3 If it is too close to the antenna of other wireless products, it will cause mutual interference,
resulting in an increase in the transmission bit error rate and a slower transmission rate.At this point, the
wireless signal must be properly attenuated. The methods of attenuating the signal include adding
obstacles, extending the distance, and adding a resistor in series between the antenna feed point and the
antenna, etc., to meet the actual application requirements;
2. Selecting a suitable power supply is the key to good and stable wireless transmission and stable
operation of the product. Improper power supply will cause damage to the product or poor wireless
performance. The selected power supply must meet the voltage range and input power requirements of
the power supply input, and the ripple must be less than the required maximum power supply ripple
(100mV);
