Thank you for your test.

I also tested the basically unchanged multi-sensor example. I tested 9 end nodes overnight, one node was offline, and the other 8 nodes were normal. The reason for being offline is unclear.
The details of the last test are explained here. The program is modified based on the multi-sensor example, adding DC voltage sampling and an accelerometer LIS3DH(using the TWI interface non-blocking mode) reading in zb_app_timer_handler, and reporting XYZ 3 16-bit data (occupying a 64-bit integers).
I am using E73-2G4M08S1C module. The signal of this module is very poor. As for why the modification caused instability, it is currently unclear. I will get some packets using a sniffer.

[quote user="cai_2020"]When I using SDK 3.2 with the multi sensor and cli router example I find the end node 40% lost link.some node was stopped,like program broken and the log was stopped too,these node need reboot,some node fall in rejoin cycle frequently,these node maybe RF signal problem.[/quote]

What HW are you running this on? If it is a DK, what version of the DK do you have?

I tested the 3.2 SDK example now, but I did not see any similar issues. Have you tried to capture a sniffer trace? If not, can you try? You can use the nRF Sniffer for 802.15.4. Save the trace as a .pcapng file (default format), and upload it here.

Best regards,

Edvin

Thank you for your reply!

The no use bullet points was deleted, I find the entrance to edit the first Q&A board.

When I using SDK 3.2 with the multi sensor and cli router example I find the end node 40% lost link.some node was stopped,like program broken and the log was stopped too,these node need reboot,some node fall in rejoin cycle frequently,these node maybe RF signal problem.

I think the SDK4.1 maybe have some bug,When the end node lost uplink to coordinator some node can't chang the state.

Hello,

[quote user=""]first log is from some nodes that leaving the network and never come back, the only way to recover is reboot,when the ZED stop operation the log is break; second log is some node is make rejoin operation after random time.[/quote]

How do you try to rejoin before the reboot? And in what way do you leave the network in the first place?

I didn't really understand the second case. And I don't understand the chinese bullet points. Can you please translate them to english?
