Typical ShockBurst
TM
TX:
1.
When the application MCU has data for a remote node, the address of the
receiving node (TX-address) and payload data (TX-payload) are clocked into
nRF905 via the SPI interface. The application protocol or MCU sets the
speed of the interface.
2.
MCU sets TRX_CE and TX_EN high, this activates a nRF905 ShockBurst
transmission.
3.
nRF905 ShockBurst:
Radio is automatically powered up.
Data package is completed (preamble added, CRC calculated).
Data package is transmitted (100kbps, GFSK, Manchester-encoded).
Data Ready is set high when transmission is completed.
4.
If AUTO_RETRAN is set high, the nRF905 continuously retransmits the
package until TRX_CE is set low.
5.
When TRX_CE is set low, the nRF905 finishes transmitting the outgoing
package and then sets itself into standby mode.
The ShockBurst
TM
mode ensures that a transmitted package that has started always
finishes regardless of what TRX_EN and TX_EN is set to during transmission. The new
mode is activated when the transmission is completed. Please see subsequent chapters
for detailed timing
For test purposes such as antenna tuning and measuring output power it is possible to set
the transmitter so that a constant carrier is produced. To do this TRX_CE must be
maintained high instead of being pulsed. In addition Auto Retransmit should be
switched off. After the burst of data has been sent then the device will continue to send
the unmodulated carrier.
