But this example doesn't have the same service like the buttonless_example... Well finally I added to my application the same code as in the buttonless_example and it works. But I can't figure how to get rid of the peermanager, at the moment I will leave it as is.

It's may not be as simple as that. There are dependencies and events you need to handle. I would suggest you to base your application on the experimental_ble_app_blinky. We don't use peer_manager in that example.

Well exactly I don't know... What I've done is unchecking the peer_manager (in sdk_config) and commenting the peer_manager_init and pm_on_ble_evt functions... An now I can't connect to the device.

Could you point out where the dependency with peer manager is ? I can see the BLE events are handled by ble_dfu_on_ble_evt() in ble_dfu.c. For example BLE_GATTS_EVT_WRITE event (when the CCCD is written) is handled in on_write(). No peer manager here.

Ok, so I need to keep the notification. Then how I can get rid of the peer_manager without messing up the example?

Hi Vea,

It's my mistake in the previous response. In the new bootloader in SDK v12 we actually send notification back before we disconnect and start the bootloader.

So you need to enable CCCD so that the notification can be sent. But I don't see any reason why peer manager needed here.

Ok, in the buttonless example I removed the check of the peer_manager and also commented the peer_manager related functions... and now I can't write on the service, also I can't activate the notifications. I'm trying to don't modify the buttonless_DFU service to keep it intact so i don't have problems later, but I think I will need to modify it...

It's not really needed for the application. You can remove that checking.

And what is the purpouse of enabling the notification before writting 0x01 to the service? Without the peer manager the notification isn't working...

Hi Vea,

For now buttonless application only needs to update the bootloader setting to set s_dfu_settings.enter_buttonless_dfu = true; and then simply trigger a reset after the the writing is finish. In our experimental_ble_app_buttonless_dfu example can find we start the process by calling enter_bootloader() to store the setting to flash, then we wait for the call back (flash_callback() ) then we call sd_ble_gap_disconnect, and when we disconnected, we reset (BLE_GAP_EVT_DISCONNECTED event in ble_dfu_on_ble_evt() ).

So no peer manage or fds needed (only fstorage needed)
