ANT DFU-OTA Update Fail

[Roshan007007]

Hello,

I am trying the ANT-OTA DFU Update using an ANT Stick and the nr51422 pca 10028 board. The ANT Updater shows that the Image Upload is completed. I am uploading the s210 OTA Tester Application. But the application is not being loaded because the ANTWare II isn't detecting the ANT broadcast from the board. Also, the size of the application, when seen from the nrfgo Studio stays the same. I'm using the SDK 10 version.

File_before_OTA.hex : This is the Hex when the experimental_ant_bootloader is loaded on the board.

File_after_OTA.hex :This is the Hex after the ota_tester is loaded on the board via OTA Updater 1.4 (via application bar) .

File_after_BootloaderOTA.hex :This is the Hex after a custom file with boootloader is loaded on the board via OTA Updater 1.4 (via bootloader bar) .

nrf51422_xxac.hex: Application to be uploaded via OTA Updater.

Thank You.

Hi Roshan,

Sorry for the late response.

We found that it was a bug that if you enable "Enable softdevice protection" when flashing the softdevice in nRFgo Studio , then the DFU bootloader won't be able to start the application.

So could you please test flashing the softdevice with the option "Enable softdevice protection" unchecked and let me know the result ?

afterOTA.hex

Bootloader: bootloader.hex

Hi Roshan,

I want the hex file you used to include into the application text box. The application hex file that you got after you compiled it with Keil/gcc. Not the one you got by dump out the flash by nrfjprog --readcode. I want to compare the hex you used with what updated in the flash.

I would strongly suggest you to test first with simple example from the SDK first before you test with your application. Please test with the ant_broadcast tx example.
