The SED-M0x
module provides a built-in “fallback app” that resides in a different area of flash memory than the normal app. This fallback
app is not affected by normal Sedona Workbench app operations, like “Get App” and “Put App” from the Sox Manager view.
The fallback app exists solely to allow reconnection to the SED-M0x
module-based node in case the normal app fails to start. The fallback app contains a bare minimum of scode to define an app
with a fixed, known Panid (0000) and user credentials (user: admin, no password).
To start the dev board up with the fallback app, hold in both pushbuttons SW1 and SW2 and then press the Reset switch (SW5). Then using Workbench’s Jennic Serial Port Tool view, you must reconfigure your USB wireless adapter to use Panid 0, and reopen a sox connection to the node.
Once connected, you can then use the Sox Manager view to re-provision the node—typically by using the Restore feature to install a previously saved Backup. Note that when the node (dev board in this case) restarts after the restore, typically its Panid is not the 0000 of the fallback app.
Therefore, to reconnect again to the restored node, you must (again) use Workbench’s Jennic Serial Port Tool view to reconfigure your USB wireless adapter back to use the required Panid. This allows you to reopen a sox connection to the node, and continue work.
