nrf51822 How to bond about hid device for windows

[mizuho]

Hi, I try to connect nrf51822 and use example "ble_app_hids_mouse". I can pair this device and I confirmed that "Notify" becomes automatic at that time in Enable. But, when turning on the power and going on Bonding once again after I dropped a point once, Notify didn't become effective automatically. If "Notify" is desable, I think hid input report is not out put.

I try to use sdk "7.1.0" ,"8.0.0" and "10.0.0" for windows 8. And I use windows inbox driver.

When there is a way by which hid Input report becomes effective automatically when making them reconnect something, please tell me.

@mizuho: If the device is bonded and get reconnected, the central doesn't have to enable notification again. The peripheral should detect it's a reconnection and start sending notification. If you can capture a sniffer trace (from the time you first connect and bond, then disconnect and reconnect) it would be easier to understand what could be wrong here.

Hi, Thank you very much for your answer. I understand movement of the central. And I don't understand a way of start sending notification after reconnection. After the peripheral did bonding and event entered BLE_GAP_EVT_SEC_INFO_REQUEST and exchanged key, event enter BLE_GAP_EVT_CONN_SEC_UPDATE. Is a special way necessary between those? Or is there a way to make an event by "on_hids_evt" begin intentionally in the peripheral? (Sorry, I don't have development dongle.)

Thank you very much! It was confirmed that you can communicate thanks to you. When the peripheral went on Bonding, I can understand that the peripheral can communicate without confirmation of BLE_HIDS_EVT_NOTIF_ENABLED. That needed only to call "sd_ble_gatts_hvx".

Hi mizuho, I assume that it worked now. The CCCD is set locally when reconnected to a bonded device by calling sd_ble_gatts_sys_attr_set() with the correct attribute value.
