trasmiting
added before each transmission for mutual cooperation with wor mode. By default, the
preamble will not be actively added;
If the user wants to reduce the power consumption of the sending end, he can set the
preamble register to 8, but he cannot interact with the module in wor mode.
LoRa
receiving
Except for the Lora sending process, the rest of the time is in the receiving mode.
If the data that needs to be replied is received, it will reply through Lora / UART.
6.4 WOR Mode (Mode 1)
type
When the device mode register = 1, the module operates in mode 1
LoRa
transmiting
Cannot send actively, but can send passively (can only be mastered by mode 0)
The preamble of the active sender must be greater than or equal to the WOR period
of the receiver, otherwise the data will not be received
The module does not add the length of the preamble by default, which needs to
be set by the customer.
LoRa
receiving
The module is periodically woken up by the low-power timer, and the control module enters
the receiving mode. If it needs to reply data, it will reply through LoRa.
Wake up
Serial wake-up can be realized by using a certain timing sequence.
6.5 Sleep Mode (Mode 2)
Type
When the device mode register = 2, the module works in mode 2
LoRa
transming
Unable to transmit wireless data.
LoRa
receiving
Unable to receive wireless data.
Wake up
Serial wake-up can be realized by using a certain timing sequence
