Hi Jacky,

The difference between nRF52832 and nRF52810 can be found in the table here.

You can read more about developing for nRF52810 here.

I'm not 100% sure why you need to test OTA on the new board even before testing with the application itself.

My suggestion is to do the following:

- Flash (with the programmer not OTA DFU) the SD + your application (for nRF52832) to test if it's functional on your nRF52810 board. If it doesn't you may need to debug and check why it doesn't work.

- Test OTA DFU with the ble_uart project (a project that showed it works on nRF52810 board) to be sure that the bootloader works.

- Final test is to do OTA DFU for your application. If it doesn't work, you need to try to debug and provide more logging information from both the phone, and the bootloader.

Hi Huang:

The trouble is that what I made OTA package in the past is depending from nrf52832 not 52810. And I have tried the Ble_uart project of 52810 which works well so the h/w platform is fine. The trouble is that from OTA package or that from application hex file itself. Is there any document guide the firmware different between nrf52832 and nrf52810?

Hi Jacky,
It depends on which softdevice you use and if you use any hardware that doesn't available on nRF52810. Also make sure you have configured the RAM configuration correctly.

I would suggest to first test the device without bootloader, simply flash softdevice and application.
After that you can test the bootloader with an example application that made for the nRF52810 before testing with your application.

Hi Huang：

Your are right and many thanks, I try use 52810 own dfutag sample hex file what it can flash and run. but I try to OTA my application package(it also made by nrf52832) then it failed. Is that the application also need adjust the address configuration? or that I need re-design my firmware base on nrf52810 project?

Hi Jacky,
From what I can see you are trying to flash a DFU bootloader made for the nRF52832 to the nRF52810.

There is a problem with it that the bootloader is always located at the end of the flash. In this case, address 0x78000 which is outside of the address range of the nRF52810 (0x0-0x30000).
I would suggest to build the bootloader from a project that made for the nRF52810 (pca10040e_s112_ble) or change the start address of your bootloader to 0x28000 , the same as in the pca10040e_s112_ble project.

Be aware that since the size of the flash of nRF52810 is smaller than nRF52832, it's quite limited on what size of the application you can update.

Also note that you don't need the bootloader to test the normal functionality of your application.

Hi Elfving：

It's simply use the dfu hex for my test, below as the link, I have put the hex file and also the script in it.

Hey Jackie!

There might be something like a bootloader placed at the end of the flash. Could you send me the hex-file?

Best regards,

Elfving
