Hello,

 Have you tried any official DFU sample? Can you try this sample from my colleague and see whether the same is happening? Which version of iOS are you trying here? I guess there is some issue with the implementation you have followed. Have you followed all the steps mentioned in this blog post.

Please see the prj:conf file from one of the sample check whether you have included every required configurations.

Kind Regards,

Thanks for your great support! I follow procedure mentions in this blog post. And I can do OTA update successfully with peripheral_lbs sample.
