How to make beacon connectable

[arjun]

Hi Nordic,

I am trying to implement DFU-OTA in beacon. For that I am trying to make beacon connectable. My requirement is to work the beacon in non-connectable mode during normal operation whereas for implementing DFU, I need to make it connectable by using a button press.

What I have implemented - when a button is pressed, I stop the advertising and start the connectable advertising.

Issue faced- I am not able to perform DFU. My reasoning is that, since I have copied the DFU relevant code snippets from working example code, there is nearly no chance of error in DFU part. So I am guessing the issue lies with transition from non-connectable to connectable mode.

Is my implementation for connectable mode correct?If there is a better way of implementing the following, please suggest..

Not exactly. Even though I was able to make it properly connectable, I was not able to perform DFU. It was crashing while performing DFU. I have however reached a solution. Earlier for the connectable mode,in the advertising_init function, I was not passing any advdata.uuids_complete.uuid_cnt and advdata.uuids_complete.p_uuids values, as there was no service other than the DFU.

Thus when I included the NUS in my application and passed its adv_uuid values to the advertising init function, it worked fine without any issues.

Is it mandatory to pass the uuid parameters in the advertising init function , for a proper connection? Or is it necessary to have a service present, other than the DFU.

I am debugging the issue. It would be helpful if you could give me some suggestion..
