2.6 : PCB design description
The power to recommend the use of LDO for DC 3.3V , provide the driving current of at least
30mA, the module of power capacitor placed a 10uF proposalIn the PCB layout, the BLE module is placed should
be kept away from the magnetic field source such as transformers and coils

2.7 : Rest
When the module network, to back network, no mobile phone APP on the network when the network back, the
need for a hardware reset reset method: power up and down in the form of (three short and two long), first power
on 1-3S, and then, repeat 3 times, then 2 long time the 5-10S on the electrical operation can be reset。
