<RX>09:15:35.72 COM6 APP_CNF_BDB_COMMISSIONING_NOTIFICATION (0x4F80)

If you read the post in detail, you should use 0x03 as input value when you use SYS_OSAL_NV_WRITE with ID:0x0003.

thanks a lot for response .

according to pics below first i did 0x03 for it and then reset to erase nv memory then i put ZERO on it and reset it again so it will store all network information and network state in nv memory . isn't that right?

If you don't want to erase network information in NV, you don't have to call SYS_OSAL_NV_WRITE with ID:0x0003.

but its default value is 2 that can erase everything

If you had write ID:0x0003 with value=0x03, you are correct and should clear it with value=0x0.

but like i said when i put zero on it two board cant find each other anymore .
i try to dont put zero on it and after reset it work fine .
after router reset it should automatically connect to coordinator right?

After router is reset, you should send APP_CNF_BDB_START_COMMISSIONING with CommissioningMode: (0x00) to make it work again.

how would u suggest to send data to one router like lamp and after reset that short address has changed , find it , and send data againt to that particular router?

If NV_RESTORE is enable, the short address shouldn't change.

how to enable NV_RESTORE? add this to #define of iar znp project?
and what if there was a conflict on short addresses?

0 YiKai Chen over 8 years ago in reply to navidrct ansari

Guru 735695 points

Yes, you should add NV_RESSTORE into znp project. Short address is handled by Z-Stack kernel and there won't be any conflict.
