user102645 over 4 years ago

Hi,

Greetings!

I am using below setup

nRF52832

Mesh SDK 4.0.0

SDK 16.0.0

Application Example: light_switch_client_nrf52832_xxAA_s132_7.0.1

Issue:

Using above setup, I use sensor server model publish the Sensing sampling data，The Sensor device work fine about a month.

From yesterday,the Sensor device do not publish sensor data.I try debug and find the NRF_ERROR_FORBIDDEN error from:

[net_state.c] net_state_iv_index_and_seqnum_alloc

the logs:

00> [15074:main.c:466]   app_sensor_get_cb,PIR:1,LIGHT:223

00> [15075:app_sensor_utils.c:488]   ERR: publication failed (0x000F (15)) = (status)

--------------------------------------------------------------------------------------

I try reboot the device and can not restore.

Our other sensor device work longer than that device and still work fine.

How to resolve this issue?

Thanks in advance.

Regards,

Hi Kai,

Your issue is pretty similar to this one: https://devzone.nordicsemi.com/f/nordic-q-a/60144/access_model_publish-returns-nrf_error_forbidden-in-lpn-and-all-friendships-time-out/247950

Do you devices reset a lot? If it does it's the problem with the sequence number increasing NETWORK_SEQNUM_FLASH_BLOCK_SIZE on every reset you have. And if the device reset very often it will be very quickly running out of sequence number (max 16777216) when the IV index is not increased yet.

In the case I pointed to there are some advice on how to remedy the issue. But it's the best if you can solve the problem if the device reset very often. The device should be put to sleep if you want to save power consumption, not to deep sleep (SYSTEM OFF) and reset when wake up.
