About the issue of nrf52833 mesh provisioning

[shenghua]

  Hi all:

　We are developing mesh project using nrf52833 based on mesh sdk 5.0. First the nrf52833 device can be sucessfully provisioned into a mesh node using mesh lpn example by the nrf mesh app.After powering off the node then power on the device, we found that the provisioned node disappeared.

  Finally the provisioning procedure is done by test nrf52840 device using th same example , we found the the node can also keep the provisoning information after powering down then powering on the device.

Below is an overview of the nrf52xxx specs.

What is the main different between the nrf52833 an nrf52840?

Can the nrf52833 keep the provisioning information after power off the device? It seems that there is no provisioning data stored in the nrf52833.

 The datalog for nrf52833 is as below.

 provisioned into a mesh node with a node address(0x000E)

 After powering down the node, the provisioned node disappeared.

Hi!

The example should work on the nRF52833. Are you using the nRF52833 DK to test the example?

Dear Joakim:

Thanks your reply. The example can work sucessfully on the nRF52833 in the RF52833 DK. 

We found that bt mesh is reset due to the noise in pin p025 after powering off then powering on in the nRF52833 hardware designed by ourselves. 

Finally we disable the codes of bt mesh reset in the button4 interrupt, the problem has been solved.

The node can also keep the provisoning information after powering down then on the device in our hardware design.

Best Regards,

ShengHua
