Does device with ANCS work well with Android?

[Ben.Qin]

Hi, there! Does peripheral with ANCS only be connected by iOS? I ran the ANCS demo in sdk 9.0, and it works well with iOS. Once an Android phone connect to it, it was connected, and then disconnected. The UART log says that the disconnect reason is 0x22, BLE_HCI_STATUS_CODE_LMP_RESPONSE_TIMEOUT in ble_hci.h. Below is Some earlier log, Apple Notification Service not discovered on the server. [DM]: >> dm_security_status_req [DM]: << dm_security_status_req As I know, some former sdk supports ANCS work with Android. We expect the product can work well with both iOS and Android. Is there any workaround? thanks!

Hi. How many seconds after connection does this happen? It might be caused by the Android device not responding to the pairing request sent by the nRF device.

About couple seconds. I comment the disconnect action when ancs gets a BLE_ANCS_C_EVT_DISCOVER_FAILED event, then disconnection doesn't happen like before when Android connects to ANCS device. It works well when ios connects to ANCS device too. I'm not sure if it is a feasible way. But this disconnection reason is BLE_HCI_REMOTE_USER_TERMINATED_CONNECTION, not BLE_HCI_STATUS_CODE_LMP_RESPONSE_TIMEOUT, would it fix the issue acceptably?

Hi Ben,

I don't think there is an ANCS server running on Android phone. ANCS is Apple Notification Center Service and was defined by Apple.

What you can do on Android is implement a GATT server with Alert Notification Profile. Then you can use the ble_app_alert_notification on the nRF51 to receive notification.
