Hi Mikhail,

Please be noted that after you call dm_device_delete_all() it won't delete the bonded information immediately but only queue the process so the softdevice will schedule and delete it later. You would need to wait for DM_EVT_SERVICE_CONTEXT_DELETED event in the device manager event handler to know that it's deleted.

Also please make sure you check the return code for dm_device_delete_all) if it returns NRF_SUCCESS or not.

void ble_reinit() {

		softdevice_handler_sd_disable();

	char device_name[2 * MAX_STRING_SIZE];
	memset (device_name, 0, 2 * MAX_STRING_SIZE);
	strncat(device_name, /*(const char*)*/hex.name, hex.name_lenght);
	strncat(device_name, /*(const char*)*/hex.serial_number, hex.serial_number_lenght);
		
	ble_stack_init();
	ble_gap_params_init(device_name, (uint8_t *)pass.passkey, get_tx_power());

}

@Mikhail: What do you have in ble_reinit() ? Please try to step into dm_device_delete_all() and see if there is any error returned.

Have you tried this example.

Hello! Yes, I tryed call

dm_device_delete_all(& m_dm_app_id);

I watching if first I call

ble_reinit();

than I call

dm_device_delete_all(& m_dm_app_id);

at this case all deleted correct. If I just call

dm_device_delete_all(& m_dm_app_id);

without

 ble_reinit();

in this case no success, like I discribe in 1-st post.

Hi Mikhail,

Have you tried to call dm_device_delete() ?

Could you check if the device re-connect and pair again? There must be something else write to the id_bitmap. You can try putting an UART/RTT log on each place that modify the id_bitmap in the code.
