Specifications

transmission abnormality.
· Antenna soldering abnormality RF signal is not reaching the antenna or π circuit i
s
solder
ed incorrectly.
4.2 Module power consumption anomaly
· The module is damaged due to static electricity, etc., resulting in abnormal power
consum
ption.
·hen doing low-power reception, incorrect timing configuration etc. leads to module power
consumption does not achieve the expected effect.
·Individually measured module or MCU are normal, the power consumption abnormalities app
ear
in
the joint tuning is due to the MCU and RF module connection pins are not handled properly.
·The working environment is harsh, in high temperature, high humidity, low temperature an
d
other extr
eme environment module power consumption will fluctuate.
4.3 Insufficient module communication distance
·The antenna impedance is not matched properly resulting in low power being transmitted.
· There
are objects such as metal around the antenna or the module is inside metal causin
g
severe
signal attenuati
on.
· There
are other interfering signals in the test environment causing the module
to
commun
icate at a close distan
ce.
· Insuff
icient power supply causes the module to transmit at an abnormal power level.
· The test environment is harsh and the signal attenuation is high.
· Module through the wall and other environments and then communicate with the other end,
the wall, etc. on the signal attenuation is very large, most of the signal is bypassed
through the wall signal attenuation is large
.
· The
module is too close to the ground is absorbed and reflected resulting in po
or
commun
ication.
