DFU FW-Update with Intel Wireless Bluetooth

RE: DFU FW-Update with Intel Wireless Bluetooth

From what I can see in the trace, the reason the Intel's DFU process was slower because:

1 - Connection interval was 150ms vs 60ms on the CSR chip.

2 - There are only 3 packets per connection event compare to 8 packets on the CSR.

On number 2, I don't think we can do anything about that, it's the limitation on the intel chip, unless you know how to change it.

On number 1. You can modify the bootloader to send a connection parameter request (sd_ble_gap_conn_param_update) to reduce the connection interval, you can try as low as 7.5ms. I don't know which value will be accepted by the Intel chip.

Note that CRC is always checked before the image is swapped.

Hello.
"So there is no BT connection to the PC"
means the ble-device has logged off the PC before the bank1 is copied into the bank0.

Yes, exactly. CRC is transmitted but not checked.

Btw. I use exactly nrfutil0.5.3 and the nRF5_SDK_11.0.0_89a8197.

Here are the logs

Next time please attach the log as a file instead of a long text like this it's very hard to read.

I'm not sure I understand what you meant by "So there is no BT connection to the PC. CRC is no used ? It is always 0. Correct me if that's not true." Which Bluetooth connection you are talking about here ? CRC always used as it's part of the init packet that sent at the beginning of the DFU process. CRC may not be checked for booting process, but it's a different matter.

It's much easier to debug using the log in the bootloader instead of the log on the central side.

To be able to spot what cause the long delay, please try capture a sniffer trace. And if you use small enough DFU image it would be quite easy to compare the trace to find the difference between the success and unsuccessful DFU.

Hello Hang,
Unfortunately, I've been busy with other things until now.
I summarize my problem:
For historical reasons, we use the nrF5 SDK 11. and the Softdevice132 2.0.1. The DFU boot loader (DualBank) used is from the SDK, which we have, of course, slightly modified (UUIDs and so on.).
On the other hand there is a Win10 and our program that does the FW upload. I have now tested various Bluetooth dongels and PC. They all work, except for Intel (of course it works too). All other dongle need up to max. 90 seconds for the 77kB image upload. It is copied temp into bank 1. Then Bank0 is deleted and Bank1 is copied to Bank 0. Then the new start addresses are flashed. That works fine. The image copy from Bank1 to Bank0 is only carried out after the device has logged off with "everything OK". So there is no BT connection to the PC. CRC is no used ? It is always 0. Correct me if that's not true.
But it's different with InteChip. It takes between 215 and 240 seconds to transfer the 77KB. Here the device also logs off with "all ok", then Bank0 is delete (it is empty! -> FFFFFF), then the device restarts.

Strange! To me it feels like a hidden timout.

I tried it with a smaller image, it behaved in the same way, so it does not depend on the size.
I also made a diff between the two images of Bank1, which are the same between Intel u. CSR.
It is just transmitted more slowly.
Should I do other tests?

FYI: The Intel driver in Windows is called
"Intel (R) Wireless Bluetooth (R)",
USB \ VID_8087 & PID_0025 & REV_0002

I checked the timing with Nordic BLE-Sniffer and Wireshark

If you look into the Intel part, there is always the Control Opcode: "LL_CHANNEL_MAP_REQ".
Can that be the trigger of the fail?
The CSR-Protocol does not have this. Everything else is the same apart from timing.

RE: DFU FW-Update with Intel Wireless Bluetooth

Hung Bui — Tue, 24 Mar 2020 16:47:42 GMT

Could you please reply in normal text ? I'm not sure why it always has to be with some kind of formatting.

Which application do you run on your PC to use the Intel chip ? I assume you wrote your own DFU master ?

We need to debug the bootloader to see why it didn't copy the image from bank 1 to bank 0, if there was any reset occurred before the bank swap happened.

The code where the swapping happen is inside dfu_activate_app() ( I assume you are testing with DFU application only).
The execution of the flash copy is occurred inside cmd_process() in pstorage_raw.c

Please try to test with very small image, just in case there is any timeout.

Have you modified anything with the bootloader?

Hi Hung
you are right, I should have mentioned it. 
Intel-BLE is built into my PC. The others are BLE-USB dongle.
The OS is the last Win10. But that doesn't seem to be the problem. 
I think it's a timeout of 240 seconds somewhere. The nR52832 is restarted. 
The Intel BLE chip is only slower, so we're here at some timeout limit of 240 Sec.
In my opinion, the data transmission and data check are finished and found to be good (always). 
The image is now in Bank1. The BLE connection is cleared down after "DFU_UPDATE_APP_COMPLETE" 
has been reported (after app. 216 seconds).Bank0 is now cleared. Then the image of Bank1 should be copied 
to Bank 0 and this rarely works with Intel. 
It always works with the other faster BLE dongles (app. 90sec).

If it failed, I checked the banks with my Jlink. 
Bank1 contains the complete new errorfree image, 
Bank0 is overwritten with 0xffff.

Hi Dudek,

It's pretty hard with the format you used in the text. Please use normal text with no formatting next time.

Please make it clear about the issue you are having. What did you use on the DFU master side ? What's running with the Intel Bluetooth chip ?

My understanding is that you have 2 issue:

1. The DFU process from the Intel chip can't complete. If it couldn't complete, what did you see ? any log ?

2. If the DFU process finished but the application image didn't run, what did you see? Did the bootloader advertise ?

There is a way to debug the DFU is to dump the flash to a hex file and compare it to the original flash (before DFU) and compare to when you do DFU with other chip.

Please try to test with very simple DFU image, for example blinking LED.
