Data delay schematic (at a serial port baud rate of 115200, sending 22 bytes)
Continuous transmission mode is divided into "Distance Priority" and "Speed Priority" two kinds of
continuous transmission strategy for users to choose (please refer to Chapter 5 for details). From the
reference data in the following table, we can see that the higher the baud rate of the serial port and
the smaller the amount of data being sent, the difference in data latency between the two strategies is
not significant. However, once the data reaches thousands of bytes, the problem of data latency will be
highlighted.

4.2 General transmission mode (mode 1)
Type
When M0 = 1 and M1 = 0, the module operates in mode 1
Tran
Transmission is done in packets at 55 bytes per packet using a user configurable air rate;
smit
The user can enter data through the serial port and the module will initiate wireless
ting
transmission.
Rece
ivin
In the non-transmitting state, data can be received normally.
