Receive and Transmit Timing
The figures and tables below show the timing information for the module when changing between
different operating states.
RXD and TXD are processes for receiving or transmitting UART data. The UART operates in full duplex,
allowing simultaneous serial transmit and receive between the module and a host processor.
RX and TX are radio states, in which the built in radio transmitter is busy ether receiving or transmitting
data.
Receive RF Packet Timing
Symbol
Value
Description / Note
t
RX
Serial data: 3.5 – 16ms
Event packet: 5.1 ms
Time from preamble detected until packet received.
t
RX_TXD
Max 1 ms
Time from packet fully received until first character sent to UART
t
TXD
Min 521 us
Number of bytes x 521 us
t
RX_ACK
2 ms - 33 ms
Time from packet fully received until Acknowledge message ready to be
transmitted, including LBT and random MAC timing
t
TX(ACK)
3.2 ms
Time to transmit ACK packet, including preamble and sync
Note: Timing diagram representative for packet transmission without collision and retry, and no wait for
clear channel delay.
