Unexpected event:24

When I try to run the 3 server, 1 client light control example, This is the log that follows:

Also, what does this error imply: provisioner.c, 235, Unexpected event: 24.

thank you Rahul

As Faik mentioned event 24 is "NRF_MESH_EVT_SAR_FAILED". It may not related to the provisioner. As you can see in the log, the provisioning was finished before the unexpected event. It could be just a corrupted SAR packet or a packet didn't receive an ACK.

Regarding <t: 876132>, nrf_mesh_node_config.c, 112, MESH ASSERT at 0x00023242, How often do you receive this ? Do you get this on all 3 servers or not ? Could you use addr2line to translate 0x00023242 to address ? Syntax should be: addr2line -e light_control_server.elf 0x23343

[rahul]

I receive this error everytime the server count is greater than 1. Also entering it into addr2line gave: 681B ldr r3, [r3]

[Hung Bui]

The result doesn't make much sense. Could you send the .elf file of the server ? Do you have any modification of the source code ? You mean the first server get configured has no problem but the 2nd and 3rd has ?
