Wireless Transceiver Module Wireless Module Serial Port 433Mhz SI4438/SI4463
Features:
At the transparent transmission mode, baud rate, and wireless
communication channel must be set to the same. The factory default
settings are FU3, 9600bps (8-bit data, no parity, 1 stop bit), and
CH100 (443MHz). This mode can automatically adjust the air baud
rate according to the serial port baud rate, and the communication
distance is the farthest at low baud rate.When using, it is
generally not limited to the number of bytes sent continuously to
the serial port of the module. However, in view of environmental
interference and other factors, when a large amount of data is
continuously transmitted at a time, some bytes may be lost.
Therefore, the host computer should have mechanisms such as
answering and resending to avoid information loss.
