2. In the long-distance ranging mode, due to the internal filter algorithm parameter calibration, the error of the
first few ranging results just after the device is powered on may be greater than the module's ranging accuracy.
3. The distance measured by the module only represents the one-way transmission distance of the radio between the
ranging host and the ranging slave, and does not necessarily represent the true distance. The user should try to measure in
an open place.
6.5 Configuration mode (mode 3)
The fixed baud rate parameter in this mode is 9600, 8N1. You can refer to the instruction format to set the corresponding
parameters of the module.

16-based format sends a C0 + 5 byte working parameters, a total of 6 bytes, must be sent
continuously (power-off saving)
16 Enciprome format sends three C1, the module returns the saved parameters, and must be
sent continuously.
16-based format sends a C2 + 5 byte working parameter, a total of 6 bytes, must be sent
continuously (power-off does not save)
16 Enciprome format sends three C3, the module returns version information, and you must be
continuously sent.
16 The binary format sends three C4, the module will generate a reset and must be sent
continuously.
In transmitting mode, the 16-en-format sends three E2, the module will enter a 10S clock
configuration window period, and can pass the corresponding parameters of the C0 command
within this 10S clock, the module uses new parameters after the 10S clock is completed.
working.
In transmission mode, the 16-en-format sends three E3, and the corresponding module
receiving this instruction will enter a 10S clock configuration window period, and can send 6
bytes of C0 command parameter air configuration module within 10S. After the parameters,
after the 10S clock, the receiving module module works with the new parameters.
