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.
