OTA over BLE NRF52832

[srinivasa m]

Hello Everyone, 

     In my project, I am using NRF52832 in my custom board, all function tasks are working fine but when it comes to OTA, the firmware file is transferred to the device from nRF connect mobile app successfully. but new firmware is not working and the device still advertising DFUtarg. OTA is happening properly with the nRF52832 development kit but when it comes to the custom board it is not happening. I have used a buttonless dfu example. 

Thank you,

Srinivasa m

Hi, 

It is tough to tell what is wrong with only this much information.

What nRF5 SDK version are you using?
Can you obtain the log from the bootloader on your custom board?
Do you update the same FW as testing on nRF52832DK? 
What do you upload, APP, SD+BL, or other combination? 
Are you able to run the new FW on your custom board before DFU?
Have you tried to reset the custom board after uploading the application?

Regards,
Amanda H.

Hello,

Thanks for your response.

"What nRF5 SDK version are you using?"

and: nRF5SDK version: nRF5_SDK_17.1.0_ddde560

Can you obtain the log from the bootloader on your custom board?
Do you update the same FW as testing on nRF52832DK? yes

What do you upload, APP, SD+BL, or other combination? 

and: I upload the application with required keys and sd version by generating the zip file. 

Are you able to run the new FW on your custom board before DFU? yes

Have you tried to reset the custom board after uploading the application? yes

 

same thing is working with nrf52832 dk without any errors

Please test with the bootloader with _debug and provide the debug log.
