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；

The antenna must not be installed inside the metal case, which will cause the transmission distance to be greatly



weakened.

GPIO0 \ GPIO1 \ GPIO2 \ GPIO3 are configurable I/O ports for various application，see more in SI4463 datasheet.



It can be floated when not used.

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.

SPI communication rate should not be set too high, usually around 1Mbps.



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.

Re-initialize register configuration when the chip is idle for higher stability.



For controlling GPIO2 ,GPIO3 externally，pin status is as follows：



the program is initialized:

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

SI44XX_GPIO_CONFIG( 0, 0, 32|0x40, 33|0x40, 0, 0, 0 );
