5.4.1 Automatic Network Access
Automatic network access function can automatically detect connection status between
module and server. When module lost connection to server or the module determines
disconnection from the server, it can automatically trigger the Join process.
When the module is powered on or reset (hot start is not enabled), if the hot start function
has been enabled and there is valid context data in the EEPROM, it will not trigger Join
process;
In OTAA mode, when automatic network access is enabled, the automatic Join process will
be triggered when the module is in one of the following situations:
 When transmitting the acknowledgement upstream frame, if
the ACK response is not received for a certain number of times, module will force the
Join process, even in manual mode.
 The network is disconnected. When sending a data frame, the
module will automatically trigger a Join operation. When the Join is successful, the
module will automatically transmit the data.
Enable auto join trigger mode, view the example below:
AT+JOIN=0,1
OK
5.4.2
Access Network Manually
In manual mode, the user decides when to execute Join process. The module will not
automatically trigger the Join process unless it is in the automatic mode case 2.When it is
abnormal in sending data continuously for multiple times, the network status should be
checked, and if it is not connected, the re-connection command should be executed.
Set a manual network access trigger mode and view an example below:
AT+JOIN=0,0
OK
5.4.3 Network Connection
When automatic Join conditions are triggered or Join process is executed manually, module
starts to execute Join process in the background. Module will try to send Join request in
