Multimedia Buttons example connection issue

[Taner]

Hello everybody,

I tested the example: https://github.com/Rallare/nrf51_ble_app_hids_kbd_consumercontrol/tree/SDK11 on my customer board (and on the DK52) with the NRF52832. After my board connects to my iphone (Firmware: 11.3.1) I can control the volume. But once decoupled, the device can no longer pair with my iphone. Android smartphones can not even recognize my board. Is there a problem with sdk11? I use the Softdevice from SDK11 132 2.0.0

Hi,

 

I can confirm that there are bonding issues with the specific branch "SDK11" that you are linking to.

This is an older example, based on SDK 11, with device manager and pstorage. I would recommend to use the latest SDK v15 for this type of development.

Could you try this branch? https://github.com/Rallare/nrf51_ble_app_hids_kbd_consumercontrol/tree/SDK15

 

Quick mock-up, hopefully there's not many bugs. I tested this with android 7.1.2, and bonding looks to be working.

 

Kind regards,

Håkon
