disconnected, and then the module will automatically trigger a network access request.
When the warm boot function is enabled, after the module is successfully connected to the
network, the module will be in the network connection state after being powered on.
6.1 Send Parameter Configuration
During data transmission, according to different application scenarios, some parameters
may need to be adjusted, such as rate adaptation, transmit power, rate, duty cycle,
application port, etc. Users should configure appropriate parameters according to their own
application.
1) Rate adaptation
The rate adaptation function is used by the server to adjust the transmission power and
rate of the module to achieve the best power saving performance. Operation example:
AT+ADR=1
OK
After the rate adaptation is turned on, the server needs to collect the signal quality of the
module, which may increase additional network traffic. For a fixed network with a stable
signal, using a fixed transmission power and rate may achieve better results.
2) Transmit power
Use the + TXPWR command to configure the default transmit power. The module will use
this default value to start transmitting data first. The transmission power setting range is
related to the frequency band. For a more detailed description, please refer to the
LoRaWAN protocol.
In order to facilitate special applications, the module can be forced to use a certain
transmit power, which can support a maximum of 22dBm. Operation example:
AT+TXPWR=22,1
OK
3) Data rate
Through the + DATARATE command to configure the default data rate, the module will
use this default value to start transmitting data first. The rate setting range depends on
the frequency band. For a more detailed description, please refer to the LoRaWAN
