4.1.5. LoRa

TM Modem State Machine Sequences

The sequence for transmission and reception of data to and from the LoRaTM modem, together with flow charts of typical

sequences of operation, are detailed below.

Data Transmission Sequence

In transmit mode power consumption is optimized by enabling RF, PLL and PA blocks only when packet data needs to be

transmitted. Figure 8 shows a typical LoRaTM transmit sequence.

Figure 8. LoRa

TM modulation transmission sequence.

 Static configuration registers can only be accessed in Sleep mode, Stand-by mode or FSTX mode.

 The LoRaTM FIFO can only be filled in Stand-by mode.

 Data transmission is initiated by sending TX mode request.

 Upon completion the TxDone interrupt is issued and the radio returns to Stand-by mode.

 Following transmission the radio can be manually placed in Sleep mode or the FIFO refilled for a subsequent Tx

operation.
