Device not connecting after DFU OTA

arjun

Hi,

I am running the BLE DFU example. I am able to perform the DFU OTA implementation successfully. The problem I am facing is that, once the application has been updated successfully, the device gets disconnected and starts advertising with new name. But when I am trying to connect to it, its disconnecting again and again.

I am using the hrm zip file for updating. The device after updating advertises as Nordic_HRM.But I am not able to connect to it.

    HI Bjorn, I was able to fix the nrfutil v 0.5.2 installation problem. The problem was with the python version. I was using python2.5. When I installed pyhthon2.7, I was able to successfully install the nrfutil.

    However after creating the zip file, I am not able to perform DFU operation. When I try to perform DFU, its reaching till "Transmitting firmware update to DFUTarg", but it does not go beyond 0% and disconnects.

    For debugging purpose, I compared the init packet of the zip file given in sdk with the one I created. There seemed to be some differences. Could you plz check and let me know.
