Hi mark,

I got none message about provisionee when i type in cc.composition_data_get(). Do you know the reason? thanks.

RE: Thread Tutorial: Practical guide for device upgrade OTA

user93192 — Thu, 07 Jan 2021 09:17:51 GMT

I need to implement using OTA to upgrade the thread.I followed the steps provided to complete the upgrade process,but it didn't success.

I have 3 nRF52840 Development Kits.
1 DK will run a Client + Bootloader.
1 DK will run a Server.
1 DK will be used as a packet sniffer.

Step 1: nRF Sniffer with Wireshark setup.
I followed the instructions and did.

Step 2: Setup for a bootloader with logging.
I don't need to log, so I didn't do this step.

Step 3: Setup for new Client firmware
I followed the instructions and did.

Step 4: Generating keys
I followed the instructions and did.

nrfutil keys generate priv.pem
nrfutil keys display --key pk --format code priv.pem --out_file dfu_public_key.c

then replace dfu_public_key.c with the <InstallFolder>\examples\dfu\dfu_public_key.c

Step 5: Command line script
I only changed the snr in the script, here is the result of the run.

Step 6: Test procedure
1. use nrfutil to flash the Server firmware to the Server DK. From the dfu folder (<InstallFolder>\examples\thread\dfu\) open a command prompt window and run the following command:

nrfutil dfu thread -f -pkg app_dfu_package.zip -p COM6 --channel 11 --panid 43981

2. Power up the client,and run script create in Step 5.

Hi Mark,

This is great research very interesting!

If I want use mesh SDK 5.0 that how to know START_OF_FLASH_MANAGER_OFFSET

UNICAST_ADDRESS_OFFSET_1 and UNICAST_ADDRESS_OFFSET_2 ?

After following all the steps, I'm running this on RasPi 4 with the command :

And it stops at line 16 in the first output shown in this article. If I remove the error catching functionality, the script executes successfully. I also tried wrapping the try-except block inside a function and calling it at the end, and that didn't work too. You've mentioned that full python programming is available to extend the functionalities but that doesn't seem so for me. Do you have any insights ?
