transmissions before stopping. Confirm that although the upstream data frame increases the
data traffic, the reliability of the data is effectively guaranteed.
Since the LoRaWAN network supports 8 upstream channels, but only supports 1
downstream channel, under normal circumstances, you should use as many
unacknowledged upstream data frames as possible to transmit data.
The module sends data through the + DTRX command. You can set the default frame type
and number of transmissions before sending data.
Example of setting frame type and transmission times:
AT+CONFIRM=0,1
OK
Among them, the first parameter indicates the default frame type, 0 indicates
unacknowledged uplink data frame, and 1 indicates acknowledged uplink data frame; the
second parameter indicates the number of transmissions, and 1 indicates transmission
once.
After setting, send data directly:
AT+DTRX=12345678
OK
Or, directly specify the frame type and number of transmissions. The specified frame type
and number of transmissions are only valid for this transmission. The following example:
AT+DTRX=0,1,12345678
OK
When the module sends successfully, it returns the status:
OK+SENT:1
When the module fails to send, it returns the status:
ERR+SENT:1
