Hi,

Attached a modified version of the ANCS example that should support buttonless DFU and sharing of bond information. See the 'diff' file in the chip for an overview of the changes I did.

error code 0x8043 (DM_DEVICE_CONTEXT_FULL) is notified to the application when the bond table is full. One possible way of handling this event is shown in this example here : github.com/.../nRF51-ble-peripheral-bond-handling

Line 446 in ANCS example.

No, I mean the device paired with the phone before OTA, and I want it still to pair with the phone automatically after OTA. But it just cannot after that, always toggled between "connected" and "disconnected".

On which line does this error occur?
Do you mean that you create a new bond every time you connect? e.g. delete the bone on iOS? I'm not sure I understand what you do to trigger this error. Note that Bond info can be retained so you don't have to create a new bond all the time.

I‘ve found out the reason why the error occurs -- the reset prepare program before dfu. I close the db discovery, disable the ancs notification, stop the adc module and stop all timers disable the gpiote in event, then it succeeds every time.

but now there's another problem. It's about bonding. the ancs sample erase the bonds by press button, but my board has no button, and I don't need to erase the bonds, the result I want is after I update the firmware, the device can quickly pair with the phone it paired before without other operations.

So I set initial value "false" to the boolean variable erase_bonds. And it did worked well for several times. However, it failed finally. Several times later, it cannot paired with the phone. The error information is :

error occurs at device_manager_evt_handler --> APP_ERROR_CHECK(event_result); error code: 0x8043

A good start would be to go through the DFU tutorial. I assume you have added all the code from the HRS example that is within BLE_DFU_APP_SUPPORT #ifdef's?
