52810， how to use dfu？

[Blue]

Hello, guys, I develop 52810 with sdk 14.1.0, i need the OTA features, but i couldn't find the dfu demo(ble secure dfu bootloader and buttonless dfu template app, pca10040e), what can i do ?

Do you give the dfu demo for 52810 later?

Hello!Some about DFU example migrated to nRF52810.

1.Modify nrf_ble_dfu_s112.c by this code:

	#if (NRF_SD_BLE_API_VERSION >= 3)// && !S112)
				case BLE_GATTS_EVT_EXCHANGE_MTU_REQUEST:
				{
						err_code = sd_ble_gatts_exchange_mtu_reply(p_ble_evt->evt.gatts_evt.conn_handle,
																											 NRF_SDH_BLE_GATT_MAX_MTU_SIZE);
						APP_ERROR_CHECK(err_code);
				} break; // BLE_GATTS_EVT_EXCHANGE_MTU_REQUEST
#if (!S112)
				case BLE_GAP_EVT_DATA_LENGTH_UPDATE_REQUEST:
				{
						ble_gap_data_length_params_t const dlp =
						{
								.max_rx_octets = BLE_GAP_DATA_LENGTH_AUTO,
								.max_tx_octets = BLE_GAP_DATA_LENGTH_AUTO,
						};

						err_code = sd_ble_gap_data_length_update(p_ble_evt->evt.gatts_evt.conn_handle,
																										 &dlp, NULL);
						APP_ERROR_CHECK(err_code);
				} break; // BLE_GAP_EVT_DATA_LENGTH_UPDATE_REQUEST
#endif
#endif

2. Firmware id for s112 is 0xA6 (--sd-req 0xA6). It used for generate dfu image.
