I use nrf52832 board by fast advertising to connect the central(surface 4 Tablet).Then the board go to sleep.when I push the button the board use direct advertising to connect the central again,but it dont connect. I use the peer manager to get the central address,when the BLE_ADV_EVT_PEER_ADDR_REQUEST event of direct advertising happens.
SDK 14.2 Softdevice 132 .Can you give me some suggestions about direct advertising to connect previous central successfully.
when first time push button ,the board can connect the central by direct advertising.In connection state, application handles things completely, then the board and central disconnect .The board go to sleep. Next time(push button no matter how many times) the board can use direct advertising ,but cannt connect.I'm confused about this problem,How to solve this problem?
Hi, can you make sure that you first delete all bonds on the central and peripheral?
I update my primary content of main.c .You can see the main code following:
1.start fast adv in the BSP_EVENT_ADVERTISING_START event of bsp_event_handler() function.
2.central and peripheral connected, device execute pm_evt_handler(). do BLE_ADV_EVT_PEER_ADDR_REQUEST event in on_adv_evt() function.
3.delete bond in BLE_GAP_EVT_CONNECTED event of ble_evt_handler() function.
4.Then everything work completely.the device go to sleep. If button is pushed, it will execute
directed_valid_peer() function to direct adv.

Can you see something unusual.They cannt reconnect with direct adv.
Hi,Kenneth . Is it a universal phenomenon that Nrf52 board cannt reconnect surface tablet with direct adv?
How can I solve this question?
Hi,
I'm sorry for the late response. Mr. Kenneth was on vacation. We will continue his investigation and test on the Surface 4.
Do you have any other PC (PC not tablet) running Windows 10 that you can test the issue ?
OK. I test peripheral with tablet(like Lenovo,CINTIQ ) not with PC. Only surface 3 or 4(win 10) has this issue that peripheral and central cant reconnect with direct adv.
Official example ble_app_hids_keyboard also has this issue when it connect to Surface 3 or 4.When I push butoon1 long time ,The nrf52 board disconnect the Surface .Then via direct adv, fast and slow adv with whitelist , but cant reconnect again.
I think they are the similar question.
Hi Zhixiang,
We are seeing more reports from other customers about the issue. Could you try a test for us to test the board vs Surface 3&4 with the ble_app_hids_keyboard in SDK v11 and SDK v12 as well ?
Hi Zhixiang,
We are seeing more reports from other customers about the issue. Could you try a test for us to test the board vs Surface 3&4 with the ble_app_hids_keyboard in SDK v11 and SDK v12 as well ?
OK. I will try it.
I program SDK 12.3 to nrf52.Then use it test with surface3. The phenomenon is the same as above.They cant reconnect with fast adv with whitelist.
I don't find sdk v11 in official website. Our last project use sdk v9 ,s130 and nrf 51 chip. It can work with surface 3 or 4 normally.
Hi again,
You can find SDK v11 here: https://developer.nordicsemi.com/nRF5_SDK/nRF5_SDK_v11.x.x/
Please test with ble_app_hids_keyboard.
This SDK v11 can reconnect again with surface 3.I bonded with Surface 3, then I turned OFF and ON Bluetooth on Surface 3. The keyboard example would then reconnect .They can reconnect may by fast adv with whitelist. So ,I think it is right to use direct adv to reconnect again.
The serial doesn't read any data. Maybe some configuration not set. This SDK code doesn't like next SDKs that have config.h . SDK v11 is a watershed. After v11,the structure of code is changed.
Can you change code that after SDK v11 to make it reconnect with surface tablet successfully. If not ,I will use SDK v11 to realize my project.
