How to upload OTA again after successful first Buttonless OTA upload?

Hi, Everyone

My development environment is PCA10028, SoftDevice 130, SDK12.3.0

I downloaded the application using nRF5_SDK_12.3.0_d7731ad \ examples \ dfu \ bootloader_secure

A downloaded program works fine

I tried "Experimental: Buttonless DFU Template Application"

I download the application download using \nRF5_SDK_12.3.0_d7731ad \ examples \ ble_peripheral \ experimental_ble_app_buttonless_dfu

Downloaded as a testing procedure at the address below

(https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v12.0.0%2Fgroup__nrf__dfu__settings.html)

A downloaded program works fine

(DFUTARG -> Nordic_Buttonless -> application program works fine)

I will try to download a modified application program

How can i download ?

In nRF Toolbox i can not find 'Nordic_Buttonless'

Regards

Alex

Thank you for your kind advice.
But I have not yet solved the buttonless dfu.
According to your advice I merged the ble_app_nus with the buttonless_dfu application
In the DfuTarg state, the program is normally downloaded.
If I set #define TEST 0 in main.c, 'Buttonless dfu' appears in scan using nRFConnect.
However, if I set #define TEST 1 in main.c and scan using nRFConnect, nothing is scanned.

Other modifications can be found in softdevice_handler.c:

p_ble_enable_params-> common_enable_params.vs_uuid_count = 2; //orig 1

I attach main.c and nrfLog.
regards,

Would you mind zipping up your whole project so I can test it?

Hi Alex,

Sorry for the delayed response. I ran your example & started a uart log, where I saw this message at the top:

SDH:DEBUG:sd_ble_enable: RAM start at 0x20001ff8
SDH:WARNING:sd_ble_enable: RAM start should be adjusted to 0x20001fe8
SDH:WARNING:RAM size should be adjusted to 0x6018

As soon as I changed the IRAM1 Start & Size, the device advertised like it should:

This custom service tutorial summarizes why the RAM needs to be increased: "Now, adding a vendor-specific UUID to the BLE stack results in the RAM requirement of the SoftDevice increasing, which we need to take into account."

Hope that helps! Have a nice day!

Hi, Bjorn

I was late to develop a product based on multilink for a month

I changed the address according to your advice and the device search is done.

However, device names and services appear as unknown.

I have attached the file. The used program used a previously uploaded zip file.

nrfutil pkg generate --hw-version 51 --sd-req 0x87 --application-version 0 --application app.hex --key-file private.key app_dfu_package.zip

In the DfuTarg state, the program is normally downloaded dfu_package.zip.

I do not know what's wrong.

I'm more confused in my head

Best regards,

Alex

Hi Alex,

Sorry for the delayed response. Have you tried changing the application version to 1 instead of 0? If you already have the application installed on your device, the bootloader most likely has stored the application version as 0. The application version should be greater than the previously stored value, as can be read in Hung Bui's blog post here:

"--application-version: By default the start number for application version is 0. To be able to update new application, the application version should equal or greater than the one the bootloader stored. This case I use 1. Read more about version rule."

Unfortunately, I do not have a 51 dev kit with me at the moment, but I will test your code tomorrow.

Kind Regards,

Bjørn
