Si4030/31/32-B1
6.6. TX Retransmission and Auto TX
The Si4030/31/32 is capable of automatically retransmitting the last packet loaded in the TX FIFO. Automatic
retransmission is set by entering the TX state with the txon bit without reloading the TX FIFO. This feature is useful
for beacon transmission or when retransmission is required due to the absence of a valid acknowledgement. Only
packets that fit completely in the TX FIFO can be automatically retransmitted.
An automatic transmission function is available, allowing the radio to automatically start or stop a transmission
depending on the amount of data in the TX FIFO.
When autotx is set in “Register 08. Operating & Function Control 2," the transceiver will automatically enter the TX
state when the TX FIFO almost full threshold is exceeded. Packets will be transmitted according to the configured
packet length. To stop transmitting, clear the packet sent or TX FIFO almost empty interrupts must be cleared by
reading register.
