[quote user="zhouhaifang"]send uart data to app .but when app send data to nrf5340 through ble ,nrf5340 reset.[/quote]

I was not able to reproduce this. I did the following:

Apply the patch to NCS v1.5.1
Build and flash the peripheral_uart project
- west build -b nrf5340dk_nrf5340_cpuapp && west flash
Open a putty terminal window and reset the chip

Connect to it from the phone and open the RX Characteristic:

Then I can see the same message in the terminal, and the chip didn't reset

I read your reply earlier today, then I got back to this ticket now and answered it right away without reading the reply again (I forgot the question and assumed you still struggled with the DFU). Sorry about that. But it seems like you were asking about something else: nRF5340 Resets when the app sends data to it.

I will look into this issue tomorrow

Do the following:

Apply the patch https://github.com/nrfconnect/sdk-nrf/compare/v1.5.1...simon-iversen:peripheral_uart_dfu.patch to NCS v1.5.1
Open cmd or bash like explained in https://devzone.nordicsemi.com/nordic/nrf-connect-sdk-guides/b/getting-started/posts/nrf-connect-sdk-tutorial---part-1-ncs-v1-4-0#h10skagp8wj210662x01aeknqi116jxom
cd into ncs/nrf/samples/bluetooth/peripheral_uart
Run:
- west build -b nrf5340dk_nrf5340_cpuapp -p
Connect the nRF53 DK to the computer and open a serial terminal (e.g. Putty)
- run nrfjprog --com and open three terminals with these com ports, the log output will show up in one of them
Run:
- west flash

You should see the following log:

Open the nRF Connect app on the mobile and connect to the "Nordic_UART_Service"
Click on DFU in the top right corner:

Select the file app_update.bin and click on "Test and confirm"
Then you should see the following log in the terminal (see that it was v1.0.0 first, then v2.0.0)

You can try to reset it again, pressing the reset button and you should see "Application version 2.0.0" all the time

I did all this and it worked perfectly for me.

If you are using Windows there are some problems regarding Windows maximum path length.

http://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/known_issues.html#build-system

The workaround is to shorten the build folder name, e.g. from “build_nrf5340dk_nrf5340_cpuappns” to “build” or place ncs closer to c://. Use "/d/v1.5.1/nrf" instead of "/d/work/ncs_v1.5.1/v1.5.1/nrf".

Simon thank you very much!!!

I am testing your suggestion .neither using git-bash.exe nor using SEGGER Embeedded studio in v1.5.1 toolchain folder ,include a header file always is a tough thing to me. results of compile always are like below shortcut:. every time when i encount this situation,i alway add a absolute path . in this compounded peripheral_ uart project ,i must add os_mgmt.c smp_bt.c and img-mgmt.c in project ,later found there is many other c files to support this project using this method . is there a few techniques i do not know?

I change project prj.conf same to prj.conf your modified,delete all sources file i added to the project in CMakeLists.txt .only a main.c in project . this main.c file i changed same as you told .i use git-bash.exe in v1.5.1 toolchain folder and west build -b nrf5340dk_nrf5340_cpuapp -d build_nrf5340dk_nrf5340_cpuapp -p ,below is the build result shortcut:,there is No such file or directory error

Can you test the following patch with NCS v1.5.1:

https://github.com/nrfconnect/sdk-nrf/compare/v1.5.1...simon-iversen:peripheral_uart_dfu.patch

It will make it possible to perform BLE DFU with the peripheral_uart sample. At least it worked for me:

zhouhaifang — Fri, 11 Jun 2021 01:26:35 GMT

Simon,thank you very much!

1. I have tried to merge peripheral_uart example and smp_svr example in one project , a ble service would do some ordinary work ,the other ble service will do DFU work , but failed .

2. I have saw a DFU method of nrf52832 through ble . when nrf52832 receive a DFU command from a connected app in phone , nrf52832 first write 0x01 in flash (address is 0 ), then reset . in the reset period ,app in phone send a DFU file , nrf52832 automatically DFU. program in nrf52832 have no code about DFU, only only only write 0x01 in address 0 flash , then reset .i am confusing this for sereral days , and just asked former engineer ,he said a DFU code have loaded in bootloader of nrf52832 . i do not know the process of this DFU and how to operate .DOES NCS1.5.0 have this method DFU nrf5340 like this?

3.maybe can use a ble device name to register two ble services, each service has it's own service connect node , it's own receive event handler, it's own send data function. but i am not skill to do this . example smp-svr own a ble service ,and example peripheral_uart own a ble service, and merge two example into one project .

RE: I want to insert a DFU module through BLE in my old ble project to upgrade my nrf5340 image

Simon — Thu, 10 Jun 2021 17:30:53 GMT

You should try to merge the peripheral_uart sample with the smp_svr sample, and create a sample peripheral_uart_smp_svr. Then you will be able to use both the UART service, as well as the SMP service:

Then you can do the following to make sure it's working

Add printk("version 1") in peripheral_uart_smp_svr-->main() and flash it to the device
1. Check if you see "Version 1" in the terminal
Change the above to printk("version 2") and build the sample peripheral_uart_smp_svr again, without flashing
Eventually you can transfer the app_update.bin from step 2 and make sure you see the log "version 2"

I tried to do this (merge peripheral_uart with smp_svr), but I encountered some issues when transferring the file. However, I can set off some time and get this to work, if you want to?

Best regards,

Simon

zhouhaifang — Wed, 09 Jun 2021 01:53:53 GMT

Simon thank for your anser

1. my project is derived from example peripheral_uart in NCS1.5.0 and final MCU used in my project will be nrf5340, so I use nrf5340dk and example peripheral_uart to start my project .

2. a ble receive event and a ble send thread are used to communicate with andriod pad or phone in my project , ble is basic and important function in my project . i nearly use example peripheral_uart 's ble function and only a little change.

3.my project is Gradually improved ，and old image will be repalced by a new better image . so i want to use andriod pad or phone app DFU old image in nrf5340 THROUGH BLE .

4.when insert DFU function in my project ,,jlink also can be used to download and debug. that is to say: two ways can update old image , first way is by JLINK ,the other way is by DFU with a app through BLE.

5. using ble DFU method like smp_svr maybe can DFU a project have no function of ble , if a project like peripheral_uart have ble function , DFU ble and project ble will conflict. last time i have showed you that smp_svr's net core image merged_CPUNET.hex is different with peripheral_uart's net core image merged_CPUNET.hex. that is to say ,only one ble can work well. if you work periperal_uart 's ble , smp_svr's ble can not work .

6. how to use a old-fashion method to upgrade old image rather than method of smp_svr : ble module in peripheral_uart running in nrf5340 receive a file (new image as a file ) from app , then nrf5340 write new image file in it's own flash area , then nrf5340 reset and load new image in flash area .

RE: I want to insert a DFU module through BLE in my old ble project to upgrade my nrf5340 image

Simon — Tue, 08 Jun 2021 12:20:30 GMT

Question 1:

You need to confirm the image (hello world) in the primary slot to prevent it from rolling back. Use the approach described here: https://devzone.nordicsemi.com/f/nordic-q-a/68695/usb-dfu-with-nrf-connect-sdk/281680#281680

You can also confirm it over SMP BLE. However, the hello world sample doesn't support BLE, so you have to create the app_update.bin file from the smp_svr instead, then you can run the confirm image command ove BLE. Please tell me if you want me to explain this in more details.

[quote user="zhouhaifang"] 2. I use SEGGER embedded studio build my peripheral_uart project . the first build image in folder \build\hci_rpmsg\zephyr is merged_CPUNET.hex(this image must first load in CPUNET core first, only load a time ) ,second build image in folder \build\zephyr is merged.hex. when Add

CONFIG_BOOTLOADER_MCUBOOT= y to prj.conf of project peripheral_uart , build solution produces the third image app_update.bin and dfu_application.zip   in folder \build\zephyr,located same folder with second image .

[/quote]

Your understanding is correct.

[quote user="zhouhaifang"]

3.first step load code of example smp_svr as you advised in nrf5340dk , second step using nRF Connect Device Manager app, commuicate with nrf5340dk through ble named Zephyr . how can i deal with merged_CPUNET.hex,,ble thread in my project peripheral_uart conflict with ble in smp_svr?

4. i have download image of smp_svr and upgrade nrf5340dk image with app_update.bin of hello_word . when i use jlink debug peripheral_uart ,always reset

[/quote]

In order for the peripheral_uart example to work you need to program the network core with merged.cpunet.hex (BLE Controller) and the application core with zephyr.hex(containing the BLE host + the peripheral uart application (if mcuboot is used, use merged.hex instead, which contains build/zephyr/zephyr.hex + build/mcuboot/zephyr/zephyr.hex).

If you perform dfu and put the hello world app into the primary slot, the ble host and peripheral uart will no longer be present and you will not be able to debug it more.

There will be no conflicts between merged.cpunet.hex in the net core and what's in the app core (smp_svr or peripheral uart) since they are located on different cores.

Please tell me if I have misunderstood you. Maybe you can tell me about your final goal, then I will be able to help you in a more constructive manner.

1. I have followed your method step by step .and use the nRF Connect Mobile app v4.24.2 DFU app_update.bin in example hello_world build folder.the debug information below :. the string:"Hello World! nrf5340dk_nrf5340_cpuapp " is exact example code 💯.but you can see the top shotcut image .when nrf5340dk board reset ,the program seem not to run the image app_update.bin of hello_word.

2. I use SEGGER embedded studio build my peripheral_uart project . the first build image in folder \build\hci_rpmsg\zephyr is merged_CPUNET.hex(this image must first load in CPUNET core first, only load a time ) ,second build image in folder \build\zephyr is merged.hex. when Add CONFIG_BOOTLOADER_MCUBOOT= y to prj.conf of project peripheral_uart , build solution produces the third image app_update.bin and dfu_application.zip in folder \build\zephyr,located same folder with second image .

4. i have download image of smp_svr and upgrade nrf5340dk image with app_update.bin of hello_word . when i use jlink debug peripheral_uart ,always reset

the nrf5340dk cpu net core have load merged_CPUNET.hex of peripheral_uart a few days ago.

Simon — Thu, 03 Jun 2021 13:13:51 GMT

That is not the nRF Connect Device Manager app, it is the nRF Connect Mobile app. Please download the nRF Connect Device Manager app.

By the way, it should be possible to perform a dfu over the SMP service using the nRF Connect Mobile app as well. In my case (using v4.24.2, a dfu button shows up to the left of 'DISCONNECT'). Maybe you need to update the app to a newer version. However, I would recommend you to use the nRF Conenct Device Manager app when performing a dfu over the mcumgr/smp protocol.

[quote user="zhouhaifang"] how to creat a project that not only can update image using a phone app through bluetooth as you have told , but also can update image through debug tools like PCA10095 ?[/quote]

If you're struggling with programming the chip, you may have to recover it first, check out Readback protection for instructions how to do it.

If you are programming a BLE application, you need to program the network core manually first, check out 2.2 nRF5340 DK-->2.2.1 Build a BLE example for instructions how to do this

You can flash the image using the debugger/programmer in many different ways:

Segger Embedded Studio: Simply click 'Build and run'

West:
- cd <name of build folder>
- west flash
  - If you're programming a ble application, the network core will automatically get programmed with the appropriate firmware
nrfjprog:
- cd <name of build folder>/zephyr
- Single image build: nrfjprog --program zephyr.hex --sectorerase
- Multi image build: nrfjprog --program merged.hex --sectorerase

zhouhaifang — Thu, 03 Jun 2021 06:27:06 GMT

Simon ,thank you .

the way you have tested of DFU maybe only load the image of \ncs\v1.4.0\zephyr\samples\subsys\mgmt\mcumgr\smp_sv to the nrf5340dk board . when you want to run your own project ,you must first download the smp_sv image to nrf5340dk board ,later palce your own project image in a phone using this method to loaddown to nrf5340dk board .

but a project always need to revise . improve ,debug , when debugging ,i should directly download new image to nrf5340dk using debug tool , rather than place new image in a phone .to use the method you have told to load in nrf5340dk board.

how to creat a project that not only can update image using a phone app through bluetooth as you have told , but also can update image through debug tools like PCA10095 ?

I assume you have the nRF5340 DK and not the nRF5340 PDK. In that case use nrf5340dk_nrf5340_cpuapp instead of nrf5340pdk_nrf5340_cpuapp.
