CC2538: Bypass device reset after devState == DEV_END_DEVICE_UNAUTH

Hi Panagiotis,

This is similar to the investigation from this E2E thread.  You can choose to create a create a different timer which either resets the device using SystemResetSoft without calling zgWriteStartupOptions (see the ZDO_DEVICE_RESET event from ZDApp) or reverts the device ZDApp state to devStartMode = MODE_REJOIN, _tmpRejoinState = true, and _NIB.nwkState = NWK_INIT (see the MODE_REJOIN devStartMode instance) to try the join process again.

Regards,

I managed to fix it by writing this:

if ( ZG_SECURE_ENABLED && ( ZDApp_RestoreNwkKey( TRUE ) == false ) )
{
// wait for auth from trust center
ZDApp_ChangeState( DEV_END_DEVICE_UNAUTH );

devStartMode = MODE_JOIN;
_NIB.nwkState = NWK_INIT;
ZDApp_ResetNwkKey(); // Clear up the old network key.
// Clear the neighbor Table and network discovery tables.
nwkNeighborInitTable();
NLME_NwkDiscTerm();
// setup a retry
ZDApp_NetworkInit(10000);

I have tested it with two coordinators. One with the same TC link key and one with a different. When I try to join the coordinator with the different TC key it enters the code above and restarts the dev state to DEV_NWK_DISC and after that when I try to join it to the coordinator with the same key, it joins as expected.

I know that I have to make a timer to wait to see if the device successfully joins before executing the above code but for now I have made a temporary solution to see if it works.

I have one more question. We have setted the device to be able to join a network for the first 30 minutes after the boot. Does any of the above code have any influence on the enable join timer? I mean that regardless what happens (except if the device joins the network) it will scan for a network to join for 30 minutes.
