* other than the default channels.
|

*

* Therefore, the state and frame counters cannot be restored after a power cycle. However,
|
||||
* if you use the `disconnect()` API to shut down the LoRaWAN protocol, the state and frame
|
||||
* counters are saved. Connecting again restores the previous session. According to the LoRaWAN
|
||||
* 1.0.2 specification, the frame counters are always reset to 0 for OTAA, and a new Join request
|
||||
* lets the network server know that the counters need a reset. The same is said about the ABP,
|
||||
* but there is no way to convey this information to the network server. For a network server,
|
||||
* an ABP device is always connected. That's why storing the frame counters is important for ABP.
|
||||
* That's why we restore frame counters from session information after a disconnection.
|

*
|

|
