l High-frequency digital routing, high-frequency analog routing, and power routing must be avoided under the module.
If it is necessary to pass through the module, assume that the module is soldered to the Top Layer, and the copper is
spread on the Top Layer of the module contact part(well grounded), it must be close to the digital part of the module
and routed in the Bottom Layer
；
l Assuming the module is soldered or placed over the Top Layer, it is wrong to randomly route over the Bottom Layer
or other layers, which will affect the module's spurs and receiving sensitivity to varying degrees
；
l It is assumed that there are devices with large electromagnetic interference around the module that will greatly affect
the performance. It is recommended to keep them away from the module according to the strength of the interference.
If necessary, appropriate isolation and shielding can be done
；
l Assume that there are traces with large electromagnetic interference (high-frequency digital, high-frequency analog,
power traces) around the module that will greatly affect the performance of the module. It is recommended to stay
away from the module according to the strength of the interference.If necessary, appropriate isolation and shielding
can be done;
l If the communication line uses a 5V level, a 1k-5.1k resistor must be connected in series (not recommended, there is
still a risk of damage)
；
l Try to stay away from some physical layers such as TTL protocol at 2.4GHz , for example: USB3.0
；
l The mounting structure of antenna has a great influence on the performance of the module. It is necessary to ensure
that the antenna is exposed, preferably vertically upward. When the module is mounted inside the case, use a good
antenna extension cable to extend the antenna to the outside
；
l The antenna must not be installed inside the metal case, which will cause the transmission distance to be greatly
weakened.
4.2 Software editing
l GPIO0 \ GPIO1 \ GPIO2 \ GPIO3 are configurable I/O ports for various application
，
see more in SI4463 datasheet.It
can be floated when not used.
l IRQ pin can also be disconnected. The SPI query mode can be used to obtain the interrupt status. However, it is
recommended to use the external interrupt of the MCU.
l SPI communication rate should not be set too high, usually around 1Mbps.
l Please refer to “Operating Modes and Timing” for SI4463 status switch
，
the switch between TX and RX should be
through Ready, can not be switched directly.
l Re-initialize register configuration when the chip is idle for higher stability.
l For controlling GPIO2 ,GPIO3 externally
，
pin status is as follows
：
In tx mode
：
GPIO2 = 0; GPIO3 = 1;
In rx mode
：
GPIO2 = 1; GPIO3 = 0;
If the SI4463 is required to control itself, the mode of the configuration pins can be as follows when
the program is initialized:
SI44XX_GPIO_CONFIG( 0, 0, 32|0x40, 33|0x40, 0, 0, 0 );
