mesh dfu timeout

[AndyM]

Hello

I'm exploring the mesh dfu transfer, get some strange results

Here is the setup

1 distributor, 1 target

On the distributor I start  the transfer with mesh models dfd start 0 0 command

In about 40 minutes it completes, and the image is applied but I get a timeout message on the distributor side

However on the target I see a message from the mcuboot that the new message was applied successfully - and actually it is working just fine

Log from the distributor and the target below

Another question

The progress in the JSON below is "50" which I think is because the function that calculates progress divides by 2:

Function cmd_dfd_receivers_get()  in dfd.c  has this lihe

uint8_t progress = bt_mesh_dfu_cli_progress(&dfd_srv->dfu) / 2;

However if I use 

mesh models dfu cli progress command it returns
DFU progress: 100 %

Bug?

Thank you

Andy

Hi, 

Are you using the unmodified samples or your own?

Please check if you call bt_mesh_dfu_srv_applied():

https://github.com/nrfconnect/sdk-nrf/blob/dece2a7f6c36674e2714b8dad7294c911548bb62/samples/bluetooth/mesh/dfu/common/src/dfu_target.c#L268-L278

https://github.com/nrfconnect/sdk-nrf/blob/dece2a7f6c36674e2714b8dad7294c911548bb62/samples/bluetooth/mesh/dfu/target/src/main.c#L132

In the new image, are you changing the node's composition data (like the number of models and elements)? I will check if we can reproduce this. Are you changing any timeouts manually?

"50" is not a bug. The output in the json is formatted in the spec units where transfer progress is calculated in 2 precent step. in other words, the output in json is not a percentage but the spec-defined format

-Amanda H.

[AndyM]

I am using unmodified samples you provided. Yes bt_mesh_dfu_srv_applied is called on the target side.

No composition changes in the image, Just the version number

Tried with and without a custom timeout, no difference. Image is transferred, applied and runs on the target just fine, but on the distributor side there is an error after the "apply" step. See logs above

Also, what is phase 10 ? Saw that several times. It's not defined in the headers. Uninitialized variable?

Another quirk I'd like to resolve is  why it fails to proceed with the batch transfer if one of the target nodes is offline

Thanks for clarifying the "50" progress thing

Can't see this in the logs.

Can you provide the full log?

I may also suggest to increase timeout_base value

This one (if you use shell to start dfu transfer): https://github.com/zephyrproject-rtos/zephyr/blob/zephyr-v3.5.0/doc/connectivity/bluetooth/api/mesh/shell.rst?plain=1#L1411

Amanda Hsieh said:

See the first log in the ticket. It is from a distribution to 8 nodes with "apply" option. As soon as the transfer to one of the nodes completed, the image was applied. That caused a timeout and the whole batch stopped.

I tried timeout 10, will try something bigger and let you know

Thank you

A new problem

I did a firmware distribution of 1 device and the transfer succeeded, so I know the process works fine

Then I  tried to distribute to 8 devices - see node list above. 992 is offline.
Its phase is listed as 10 which does not exist in phase enumeration. But that's the least of my worries

After I sent  "mesh models dfd start 0 0 0 false 7 120"  command I did

"mesh models dfd receivers-get 0 20" periodically but the 
"progress" field remained at 0 for over 5 minutes at which point I canceled the distribution with 
"mesh models dfd cancel" command

After that all my 8 target nodes fail to boot.

Messages in the target node:

*** Booting nRF Connect SDK v3.5.99-ncs1-1 ***
 Recovering the firmware upload
*** Booting nRF Connect SDK v3.5.99-ncs1-1 ***

*** Booting nRF Connect SDK v3.5.99-ncs1-1 ***

messages repeat

In the image recovery handler of the target sample there is  this comment

    /* TODO: Need to recover the effect. */

Why is this handler called after the distribution was cancelled?

How do I fix this ?

I am curious, did you test batch distribution? How many targets?  Did you test with some nodes offline? Did you test with more targets than the default 8?

Makes me nervous to deploy this feature if  a simple cancel bricks all devices. Hope this is something that I am doing wrong and there is a fix

Thanks

phase 10 is the DFU phase, not the dfd phase and is unknown phase which means that no response was ever received from that node:

- https://github.com/zephyrproject-rtos/zephyr/blob/39917ae5e6423fe74edce399b927ddff38670817/include/zephyr/bluetooth/mesh/dfu.h#L73-L74

- https://github.com/zephyrproject-rtos/zephyr/blob/39917ae5e6423fe74edce399b927ddff38670817/include/zephyr/bluetooth/mesh/dfu_cli.h#L63-L64

Progress 0 is because the node with address 992 didn't respond to the Firmware Update Start message, but by the dfu procedure the distributor must get a response from all nodes before starting sending the blob.

timeout_base 120 means that the actual timeout for each DFU phase is 10 * 1000 * (120 + 2) + 7 * 100 = ~20 minutes.

The distributor will repeat the request CONFIG_BT_MESH_BLOB_CLI_BLOCK_RETRIES times, which is 5 by default. So, it will repeat every 4 minutes. The reason I asked to increase timeout_base is because most likely the timeout was shorter than the time needed for devices to flash the new firmware. They need to adjust the timeout based on their setup.

 

Also, since it is a unicast transfer, every chunk transmission will require confirmation from a node which may delay the transfer even more. I recommend to use multicast transfer for nodes more than 2. For this, they need to subscribe all DFU and blob models to the same address and set `group` field to that address in `mesh models dfd start` command.

 

The comment `/* TODO: Need to recover the effect. */` means that the image effect (`img_effect` variable) which is set in `dfu_meta_check` function is not stored anywhere. This code is called after reboot when DFU model recovers the abandoned DFU transfer and is needed to take a decision at the apply phase (see `dfu_appply` function in the same sample).

 

If target devices start to reboot cyclically I suggest to check if `CONFIG_RESET_ON_FATAL_ERROR` Kconfig option is enabled in `build/target/zephyr/.config` and disable it explicitly in the prj.conf. Then run the devices again.

 

I still would like to see the complete log from the distributor and target nodes. Like the first one from RTT that you attached.

Regarding the multicast transfer

Amanda Hsieh said:

I assume you are referring to the target nodes?

Amanda Hsieh said:

Progress 0 is because the node with address 992 didn't respond to the Firmware Update Start message, but by the dfu procedure the distributor must get a response from all nodes before starting sending the blob.

This is unfortunate. On a live mesh network with many nodes there will always be a node that would not respond for a variety of reasons. If the whole process is blocked by just one node it makes it not very usable in a real life situation. 

I will provide the logs you requested. May take a while

Thanks a lot for your help

[AndyM]

Here is the log from the distributor right before the image finished transferring

Questions

1. What do the  warnings about "no free slots for segmented messages" mean? Is it something that needs to be addressed? Number of slots increased?

2. Timeout base was set to 10. Still got an error applying on the distributor side. On the target side the image was applied and is running 

Thoughts?

Thank you
