6.1.3.2 Instructions for the Use of Reset
The module supports reset function. By pulling down the RESET signal more than 40 ms
(recommended value is 50 ms), over 60ms, the module will RESET again ,the module can be reset to the
initial state. After releasing the RESET, the module will restart. RESET can be suspended when not in use.
The low level voltage when pulling down RESET to start must be less than or equal to 0.5V.
RESET control sequence is shown in the following figure:

Remarks:
RESET is a sensitive signal. It is recommended to add a de-jitter capacitor near the module
end. PCB layouts should be far away from radio frequency interference and do a good job of
packet processing, while avoiding the edge and surface alignment of PCB (to avoid ESD causing
module reset).
