Peer Manager event dispacthing - NRF52832 SDK 15.0.0

[lbe]

Good morning everyone,

I am having a lot of problems configuring the Peer Manager. 

I read several discussions on the topic, but either they are old (referring to ble_evt_dispatch now removed) or they already start

from a point where I am still not.

Essentially, I want to limit the number of devices allowed to connect to 1, i.e. the first one which pairs with my device.

To do this, I want to use the Peer Manager.

Well, my problems already start here: I tried several examples (hids_keyboard, proximity.....). I also tried to check the configurations

following the tutorial on the Peer Manager usage, but all cases, the pm_evt_handler function

is never called. When debugging with the nrf development kit and segger studio, I only see the "Connect" event from the ble_evt_handler,

but the Peer Manager does not seem to get notified about the correct event.

So, my first and trivial question is: how to enable the Peer Manager to receive events?

Once I am able to have the function pm_evt_handler called, I think I can figure out the rest, but for the moment I am really stuck at this point and I hope

someone can help me figuring out what's wrong.

Thank you very much for the help!

It may be worth specifying that I had problems when trying to bond an IOs device (IPhone 7 plus). Apparently, if I use an Android device, the pm_evt_handler is called when using the application proximity....Do you have any idea about this?

Hi, 

 

How did you connect to the device from the Iphone ? Using which app ? 

How did you trigger a bonding from the Iphone ? If you don't trigger a bonding, there won't be any peer manager activity. 

When you test ble_app_hids_keyboard, what did you see ? That example basically does what you wanted to do, advertise with whitelist after the first phone bond to it.

Hello,

thanks for your reply. For the NRF52 I used the ble_app_template as a starting point, then I added more functionalities; the IOS app is an application I coded myself. As far as I know, I cannot trigger a bonding from the IPhone....this is managed by the IOs (again, this is my understanding). The question I have is why the bonding is not triggered, thus causing the peer manager callback to never be invoked

You would need to read the Apple Design Guideline at section 10.10

Basically in your app you should read a characteristic that requires bonding, then when the phone see the error insufficient authentication it will start bonding/pairing.

Thank you for pointing me in the right direction, this seems to be the reason why I cannot bond. I will follow the guidelines you indicated. I accepted your answer.
