NOTE
 The MSB method requires the module to register with a network, and will incur data traffic
during positioning. When the MSB positioning fails, the module will automatically switch to
the Standalone positioning if NV3756=1, but will not switch to the Standalone positioning if
NV3756=0.
 During the AGPS positioning process, please do not search the network, because this
operation will influence the positioning time.
