The module starts the reception test. At this time, if the bit error rate is less than 1%,

the module's red light flashes uniformly. After sending the receive sensitivity test

command, it can be delayed for a period of time.

Hibernation test: Send the hibernation command, the module enters the hibernation state,

and the hibernation state requires the module to be powered on before entering other

states. The module needs to be powered on again after the test

9.1, version information

The power-on version information displays 36 bytes, such as "VCWF-2E80-DE-XXD20-

20160302-Vsp1.00", where "20160302 is the compilation date and" Vsp1.00 "is the version

information
